In the regions of southern Andhra Pradesh, rice brown spot, rice blast, and rice sheath blight have emerged as the most prevalent diseases. The goal of this research is to increase the precision and effectiveness of disease diagnosis by proposing a framework for the automated recognition and classification of rice diseases. Therefore, this work proposes a hybrid approach with multiple stages. Initially, the region of interest (ROI) is extracted from the dataset and test images. Then, the multiple features are extracted, such as color-moment-based features, grey-level cooccurrence matrix (GLCM)-based texture, and shape features. Then, the S-particle swarm optimization (SPSO) model selects the best features from the extracted features. Moreover, the deep belief network (DBN) model trained by SPSO is based on optimal features, which classify the different types of rice diseases. The SPSO algorithm also optimized the losses generated in the DBN model. The suggested model achieves a hit rate of 94.85% and an accuracy of 97.48% with the 10-fold cross-validation approach. The traditional machine learning (ML) model is significantly less accurate than the area under the receiver operating characteristic curve (AUC), which has an accuracy of 97.48%.
Convolutional neural networks (CNN) trained using deep learning (DL) have advanced dramatically in recent years. Researchers from a variety of fields have been motivated by the success of CNNs in computer vision to develop better CNN models for use in other visually-rich settings. Successes in image classification and research have been achieved in a wide variety of domains throughout the past year. Among the many popularized image classification techniques, the detection of plant leaf diseases has received extensive research. As a result of the nature of the procedure, image quality is often degraded and distortions are introduced during the capturing of the image. In this study, we look into how various CNN models are affected by distortions. Corn-maze leaf photos from the 4,188-image corn or maize leaf Dataset (split into four categories) are under consideration. To evaluate how well they handle noise and blur, researchers have deployed pre-trained deep CNN models like visual geometry group (VGG), InceptionV3, ResNet50, and EfficientNetB0. Classification accuracy and metrics like as recall and f1-score are used to evaluate CNN performance.

This document presents a method for classifying plant leaf diseases from color images using texture and color features extracted from the images along with an artificial neural network classifier. The proposed system first preprocesses the input images, then extracts color features like mean and standard deviation of HSV color space and texture features like energy, contrast, homogeneity and correlation using a gray level co-occurrence matrix. These features are then used to train a backpropagation neural network classifier to automatically classify test images into disease categories. Experimental results show the backpropagation network provides high accuracy for plant disease classification, with 97.2% accuracy on validation data and lower error rates than support vector machines.

IRJET - Deep Multiple Instance Learning for Automatic Detection of Diabetic R...IRJET Journal
This document describes a proposed method for using deep multiple instance learning to automatically detect diabetic retinopathy in retinal images. Diabetic retinopathy is a complication of diabetes that can cause vision loss or blindness. The proposed method treats retinal images as "bags" containing "instances" of image patches. A deep learning model is trained using only image-level labels to both detect diabetic retinopathy images and identify lesions within images. The model first preprocesses images to normalize factors like scale and illumination. It then segments lesions and extracts features before classifying images using convolutional neural networks. The goal is to provide explicit locations of lesions to aid clinicians while leveraging large datasets typically required for deep learning.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Wide application of proportional-integral-differential (PID)-regulator in industry requires constant improvement of methods of its parameters adjustment. The paper deals with the issues of optimization of PID-regulator parameters with the use of neural network technology methods. A methodology for choosing the architecture (structure) of neural network optimizer is proposed, which consists in determining the number of layers, the number of neurons in each layer, as well as the form and type of activation function. Algorithms of neural network training based on the application of the method of minimizing the mismatch between the regulated value and the target value are developed. The method of back propagation of gradients is proposed to select the optimal training rate of neurons of the neural network. The neural network optimizer, which is a superstructure of the linear PID controller, allows increasing the regulation accuracy from 0.23 to 0.09, thus reducing the power consumption from 65% to 53%. The results of the conducted experiments allow us to conclude that the created neural superstructure may well become a prototype of an automatic voltage regulator (AVR)-type industrial controller for tuning the parameters of the PID controller.

This review focuses on the importance of identifying potential fishing zones in seawater for sustainable fishing practices. It explores features like sea surface temperature (SST) and sea surface height (SSH), along with classification methods such as classifiers. The features like SST, SSH, and different classifiers used to classify the data, have been figured out in this review study. This study underscores the importance of examining potential fishing zones using advanced analytical techniques. It thoroughly explores the methodologies employed by researchers, covering both past and current approaches. The examination centers on data characteristics and the application of classification algorithms for classification of potential fishing zones. Furthermore, the prediction of potential fishing zones relies significantly on the effectiveness of classification algorithms. Previous research has assessed the performance of models like support vector machines, naïve Bayes, and artificial neural networks (ANN). In the previous result, the results of support vector machine (SVM) were 97.6% more accurate than naive Bayes's 94.2% to classify test data for fisheries classification.

As demand for smaller, quicker, and more powerful devices rises, Moore's law is strictly followed. The industry has worked hard to make little devices that boost productivity. The goal is to optimize device density. Scientists are reducing connection delays to improve circuit performance. This helped them understand three-dimensional integrated circuit (3D IC) concepts, which stack active devices and create vertical connections to diminish latency and lower interconnects. Electrical involvement is a big worry with 3D integrates circuits. Researchers have developed and tested through silicon via (TSV) and substrates to decrease electrical wave involvement. This study illustrates a novel noise coupling reduction method using several electrical involvement models. A 22% drop in electrical involvement from wave-carrying to victim TSVs introduces this new paradigm and improves system performance even at higher THz frequencies.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants.

Fossil fuel consumption increased quickly, contributing to climate change
that is evident in unusual flooding and draughts, and global warming. Over
the past ten years, women's involvement in society has grown dramatically,
and they succeeded in playing a noticeable role in reducing climate change.
A bibliometric analysis of data from the last ten years has been carried out to
examine the role of women in addressing the climate change. The analysis's
findings discussed the relevant to the sustainable development goals (SDGs),
particularly SDG 7 and SDG 13. The results considered contributions made
by women in the various sectors while taking geographic dispersion into
account. The bibliometric analysis delves into topics including women's
leadership in environmental groups, their involvement in policymaking, their
contributions to sustainable development projects, and the influence of
gender diversity on attempts to mitigate climate change. This study's results
highlight how women have influenced policies and actions related to climate
change, point out areas of research deficiency and recommendations on how
to increase role of the women in addressing the climate change and
achieving sustainability. To achieve more successful results, this initiative
aims to highlight the significance of gender equality and encourage
inclusivity in climate change decision-making processes.
Voltage and frequency control of microgrid in presence of micro-turbine inter...IJECEIAES
The active and reactive load changes have a significant impact on voltage
and frequency. In this paper, in order to stabilize the microgrid (MG) against
load variations in islanding mode, the active and reactive power of all
distributed generators (DGs), including energy storage (battery), diesel
generator, and micro-turbine, are controlled. The micro-turbine generator is
connected to MG through a three-phase to three-phase matrix converter, and
the droop control method is applied for controlling the voltage and
frequency of MG. In addition, a method is introduced for voltage and
frequency control of micro-turbines in the transition state from gridconnected mode to islanding mode. A novel switching strategy of the matrix
converter is used for converting the high-frequency output voltage of the
micro-turbine to the grid-side frequency of the utility system. Moreover,
using the switching strategy, the low-order harmonics in the output current
and voltage are not produced, and consequently, the size of the output filter
would be reduced. In fact, the suggested control strategy is load-independent
and has no frequency conversion restrictions. The proposed approach for
voltage and frequency regulation demonstrates exceptional performance and
favorable response across various load alteration scenarios. The suggested
strategy is examined in several scenarios in the MG test systems, and the
simulation results are addressed.

identification of a Li-ion battery, employing a nonlinear autoregressive with
exogenous inputs (NARX) model. The proposed approach integrates the
benefits of nonlinear modeling with the adaptability of the NARX structure,
facilitating a more comprehensive representation of the intricate

Smart grid deployment: from a bibliometric analysis to a surveyIJECEIAES
Smart grids are one of the last decades' innovations in electrical energy.
They bring relevant advantages compared to the traditional grid and
significant interest from the research community. Assessing the field's
evolution is essential to propose guidelines for facing new and future smart
grid challenges. In addition, knowing the main technologies involved in the
deployment of smart grids (SGs) is important to highlight possible
shortcomings that can be mitigated by developing new tools. This paper
contributes to the research trends mentioned above by focusing on two
objectives. First, a bibliometric analysis is presented to give an overview of
the current research level about smart grid deployment. Second, a survey of
the main technological approaches used for smart grid implementation and
their contributions are highlighted. To that effect, we searched the Web of
Science (WoS), and the Scopus databases. We obtained 5,663 documents
from WoS and 7,215 from Scopus on smart grid implementation or
deployment. With the extraction limitation in the Scopus database, 5,872 of
the 7,215 documents were extracted using a multi-step process. These two
datasets have been analyzed using a bibliometric tool called bibliometrix.
The main outputs are presented with some recommendations for future
research.
Use of analytical hierarchy process for selecting and prioritizing islanding ...IJECEIAES
One of the problems that are associated to power systems is islanding
condition, which must be rapidly and properly detected to prevent any
negative consequences on the system's protection, stability, and security.
This paper offers a thorough overview of several islanding detection
strategies, which are divided into two categories: classic approaches,
including local and remote approaches, and modern techniques, including
techniques based on signal processing and computational intelligence.
Additionally, each approach is compared and assessed based on several
factors, including implementation costs, non-detected zones, declining
power quality, and response times using the analytical hierarchy process
(AHP). The multi-criteria decision-making analysis shows that the overall
weight of passive methods (24.7%), active methods (7.8%), hybrid methods
(5.6%), remote methods (14.5%), signal processing-based methods (26.6%),
and computational intelligent-based methods (20.8%) based on the
comparison of all criteria together. Thus, it can be seen from the total weight
that hybrid approaches are the least suitable to be chosen, while signal
processing-based methods are the most appropriate islanding detection
method to be selected and implemented in power system with respect to the
aforementioned factors. Using Expert Choice software, the proposed
hierarchy model is studied and examined.
Enhancing of single-stage grid-connected photovoltaic system using fuzzy logi...IJECEIAES
The power generated by photovoltaic (PV) systems is influenced by
environmental factors. This variability hampers the control and utilization of
solar cells' peak output. In this study, a single-stage grid-connected PV
system is designed to enhance power quality. Our approach employs fuzzy
logic in the direct power control (DPC) of a three-phase voltage source
inverter (VSI), enabling seamless integration of the PV connected to the
grid. Additionally, a fuzzy logic-based maximum power point tracking
(MPPT) controller is adopted, which outperforms traditional methods like
incremental conductance (INC) in enhancing solar cell efficiency and
minimizing the response time. Moreover, the inverter's real-time active and
reactive power is directly managed to achieve a unity power factor (UPF).
The system's performance is assessed through MATLAB/Simulink
implementation, showing marked improvement over conventional methods,
particularly in steady-state and varying weather conditions. For solar
irradiances of 500 and 1,000 W/m2
, the results show that the proposed
method reduces the total harmonic distortion (THD) of the injected current
to the grid by approximately 46% and 38% compared to conventional
methods, respectively. Furthermore, we compare the simulation results with
IEEE standards to evaluate the system's grid compatibility.

Photovoltaic systems have emerged as a promising energy resource that
caters to the future needs of society, owing to their renewable, inexhaustible,
and cost-free nature. The power output of these systems relies on solar cell
radiation and temperature. In order to mitigate the dependence on
atmospheric conditions and enhance power tracking, a conventional
approach has been improved by integrating various methods. To optimize
the generation of electricity from solar systems, the maximum power point
tracking (MPPT) technique is employed. To overcome limitations such as
steady-state voltage oscillations and improve transient response, two
traditional MPPT methods, namely fuzzy logic controller (FLC) and perturb
and observe (P&O), have been modified. This research paper aims to
simulate and validate the step size of the proposed modified P&O and FLC
techniques within the MPPT algorithm using MATLAB/Simulink for
efficient power tracking in photovoltaic systems.
Adaptive synchronous sliding control for a robot manipulator based on neural ...IJECEIAES
Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.

A remote laboratory utilizing field-programmable gate array (FPGA) technologies enhances students’ learning experience anywhere and anytime in embedded system design. Existing remote laboratories prioritize hardware access and visual feedback for observing board behavior after programming, neglecting comprehensive debugging tools to resolve errors that require internal signal acquisition. This paper proposes a novel remote embeddedsystem design approach targeting FPGA technologies that are fully interactive via a web-based platform. Our solution provides FPGA board access and debugging capabilities beyond the visual feedback provided by existing remote laboratories. We implemented a lab module that allows users to seamlessly incorporate into their FPGA design. The module minimizes hardware resource utilization while enabling the acquisition of a large number of data samples from the signal during the experiments by adaptively compressing the signal prior to data transmission. The results demonstrate an average compression ratio of 2.90 across three benchmark signals, indicating efficient signal acquisition and effective debugging and analysis. This method allows users to acquire more data samples than conventional methods. The proposed lab allows students to remotely test and debug their designs, bridging the gap between theory and practice in embedded system design.

Efficiently identifying and resolving code smells enhances software project quality. This paper presents a novel solution, utilizing automated machine learning (AutoML) techniques, to detect code smells and apply move method refactoring. By evaluating code metrics before and after refactoring, we assessed its impact on coupling, complexity, and cohesion. Key contributions of this research include a unique dataset for code smell classification and the development of models using AutoGluon for optimal performance. Furthermore, the study identifies the top 20 influential features in classifying feature envy, a well-known code smell, stemming from excessive reliance on external classes. We also explored how move method refactoring addresses feature envy, revealing reduced coupling and complexity, and improved cohesion, ultimately enhancing code quality. In summary, this research offers an empirical, data-driven approach, integrating AutoML and move method refactoring to optimize software project quality. Insights gained shed light on the benefits of refactoring on code quality and the significance of specific features in detecting feature envy. Future research can expand to explore additional refactoring techniques and a broader range of code metrics, advancing software engineering practices and standards.

Rapidly and remotely monitoring and receiving the solar cell systems status parameters, solar irradiance, temperature, and humidity, are critical issues in enhancement their efficiency. Hence, in the present article an improved smart prototype of internet of things (IoT) technique based on embedded system through NodeMCU ESP8266 (ESP-12E) was carried out experimentally. Three different regions at Egypt; Luxor, Cairo, and El-Beheira cities were chosen to study their solar irradiance profile, temperature, and humidity by the proposed IoT system. The monitoring data of solar irradiance, temperature, and humidity were live visualized directly by Ubidots through hypertext transfer protocol (HTTP) protocol. The measured solar power radiation in Luxor, Cairo, and El-Beheira ranged between 216-1000, 245-958, and 187-692 W/m 2 respectively during the solar day. The accuracy and rapidity of obtaining monitoring results using the proposed IoT system made it a strong candidate for application in monitoring solar cell systems. On the other hand, the obtained solar power radiation results of the three considered regions strongly candidate Luxor and Cairo as suitable places to build up a solar cells system station rather than El-Beheira.

Over the past few years, the internet of things (IoT) has advanced to connect billions of smart devices to improve quality of life. However, anomalies or malicious intrusions pose several security loopholes, leading to performance degradation and threat to data security in IoT operations. Thereby, IoT security systems must keep an eye on and restrict unwanted events from occurring in the IoT network. Recently, various technical solutions based on machine learning (ML) models have been derived towards identifying and restricting unwanted events in IoT. However, most ML-based approaches are prone to miss-classification due to inappropriate feature selection. Additionally, most ML approaches applied to intrusion detection and prevention consider supervised learning, which requires a large amount of labeled data to be trained. Consequently, such complex datasets are impossible to source in a large network like IoT. To address this problem, this proposed study introduces an efficient learning mechanism to strengthen the IoT security aspects. The proposed algorithm incorporates supervised and unsupervised approaches to improve the learning models for intrusion detection and mitigation. Compared with the related works, the experimental outcome shows that the model performs well in a benchmark dataset. It accomplishes an improved detection accuracy of approximately 99.21%.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

In the regions of southern Andhra Pradesh, rice brown spot, rice blast, and rice
sheath blight have emerged as the most prevalent diseases. The goal of this
research is to increase the precision and effectiveness of disease diagnosis by
proposing a framework for the automated recognition and classification of rice
diseases. Therefore, this work proposes a hybrid approach with multiple
stages. Initially, the region of interest (ROI) is extracted from the dataset and
test images. Then, the multiple features are extracted, such as color-moment-
based features, grey-level cooccurrence matrix (GLCM)-based texture, and
shape features. Then, the S-particle swarm optimization (SPSO) model selects
the best features from the extracted features. Moreover, the deep belief
network (DBN) model trained by SPSO is based on optimal features, which

optimized the losses generated in the DBN model. The suggested model
achieves a hit rate of 94.85% and an accuracy of 97.48% with the 10-fold

1. INTRODUCTION
Among the most significant food crops for our population is rice. The production of the rice planting
business has been rising steadily in recent years, but there are still certain negative elements, including rice
diseases, that are reducing its yield. In the frigid regions of northern China, rice brown spots, sheath blight, and
blast are currently the most prevalent diseases [1], [2]. It can happen at any time during the rice plant’s growth
cycle, which has a significant influence on the rice’s quality and yield and, in extreme situations, can result in
no output. This will not only have a negative influence on farmer income but also negatively impact China’s
fiscal revenue and food security. Now, the methods for identifying rice diseases primarily rely on farmers’
judgment, checking disease books or doing an Internet search, consulting agricultural technicians, or asking a
plant expert for assistance. Human eyes are not very good at identification, and recognition is much more
individualized. A lapse in judgement prevents the proper identification of obstacles to achieving diseases. The

number of books is updated at a sluggish rate, and due to the volume of information on the internet, it is
accuracy cannot be guaranteed. Speaking with plant and agricultural technicians, a significant amount of time,
money, and resources will be devoured. Much money and time will be spent, and it is simple. to pass up the
ideal chance for treating diseases. Therefore, developing a new, effective method for detecting rice disease a
technique to substitute the prevalent human eye recognition technique is essential to resolving the issue of rice
disease identification, which has significant study consequences.
Though no study has been conducted till date that involves the combination of the S-particle swarm
optimization (SPSO) and deep belief network (DBN) because the SPSO and DBN are not compatible, rice
disease identification has a lot of potential. According to traditional identification’s flaws and limitations, we
proposed a DBN-based method and SPSO for detecting rice brown spot, sheath blight, and blast. Images from
the database of rice diseases were used by the DBN. Models such as SPSO are trained in two phases. First and
foremost, deep belief network-restricted Boltzmann machine (RBMs) are used to build the model. The
gradient's descent comes next. The DBN is trained using the SPSO method. As a categorizer, the SPSO and
DBN are then assessed with 10-fold cross-validation.
These are the primary advances made in this study: SPSO and DBN approaches are used to precisely
extract the rice disease spot’s edge in a new framework for the usual detection of rice diseases that addresses
issues with the rice disease spot’s image segmentation. The suggested DBN and SPSO could detect the area of
interest that is acquired by preprocessing the images of rice diseases by learning disease spot characteristics.
In terms of feature characteristics, segmentation, and peak signal-to-noise ratio (SNR) experimental findings
demonstrate the great accuracy of this approach. Because of this study, the field of rice disease identification
is better integrated than it is with the traditional diagnostic technique for diagnosing rice diseases, and DBN
and SPSO algorithms are combined for rice disease using machine learning (ML) technology. The initial
identification significantly enhances the timeliness and precision of rice disease management and has practical
relevance.
2. METHOD
The two strategies for classifying data are supervised learning classification and unsupervised learning
classification. This study aims to extract features or traits from visual data. By using a supervised learning
system, the information is used to categorize the images. Learning to recognize an image based on data and
labels, including data mining, the traits of image classification provide us with knowledge. To determine the
type of data, we can apply a classification algorithm to fresh images. Specifically, we extract the numerical
image’s vector of features before using the ML approach to apply categorized information.
New techniques and approaches for quick and precise pattern recognition have emerged in recent
years, thanks to the quick growth of computer vision, digital image processing, and pattern recognition
technologies. Because of the rapid advancement of digital image pattern recognition technologies, processing,
and computer vision, plant disease classification, diagnosis, and nondestructive detection, these sophisticated
diagnostic techniques have had significant success in both theoretical study and real-world implementation
[3]–[5]. However, the effectiveness of diagnosis is often subpar due to the limitations of theoretical analysis,
the requirement for specialized talents, and the necessity for extensive experience and knowledge during
training.
A probabilistic generation model called DBN is used during this period and is made up of numerous
constrained RBMs [6]–[8]. Layer-by-layer stacking of the RBMs allows them to extract characteristics from
the original data, which allows us to get certain high-level depictions of the original data [9]. This deep learning
(DL) model’s central idea is to use a layer-by-layer greedy learning method to optimize the link deep neural
network’s weight. Initially, to identify the rice disease characteristics, the training method is unsupervised
layer-by-layer. The supervised learning process is reversed after adding the relevant classifier.
By switching to PSO, which achieves a balance between the global and local search methods by
introducing a mode-dependent velocity update, we produced better results by using the SPSO technique to
convert the optimization issue with limitations into an optimization issue without constraints. Numerous
researchers have used the DBN in recent years in a variety of application fields, including face, speech, and
image recognition, as well as the classification of plant leaves. A fundamental concept for feature extraction
and following image identification for original images is presented by this multi-layer network design. The
DBN has gained popularity [10].
Agriculture is the backbone of most countries. The early prediction of disease in rice plants can
increase productivity and be helpful to farmers. However, the conventional ML models were focused on basic
feature extraction. Moreover, the existing methods did not implement any feature selection mechanism. So,
this work implemented a hybrid mechanism with multiple stages. Figure 1 shows the proposed rice disease
image recognition flowchart. Initially, the region of interest (ROI) is extracted from the dataset and test images.
Then, the multiple features are extracted, such as color, texture, and shape, using ROI properties. Here, the
3. ISSN: 2088-8708

color features are extracted in first order, second order, and third order using the mean proposition. Here, the
texture features are extracted using the grey-level cooccurrence matrix (GLCM). The extracted texture features
are energy, or angular second order moment (ASM), entropy, contrast, and inverse difference momentum
(IDM). Then, the features are combined using feature fusion. Further, the SPSO operation is introduced to
select the optimal features. Finally, the DBN model is trained with the dataset features, which store the feature
memory. In addition, the DBN testing model is used to perform image testing, which resulted in a disease
recognition operation. The proposed SPSO-DBN model recognizes rice blast, sheath blight, and brown
spot-based disease classes, as well as healthy rice image recognition.

2.1. Dataset
The rice disease images were taken on the rice trail domain of “The Heilongjiang Academy of
Agricultural Reclamation Sciences,” China, using a vivo Y33T smartphone (12 million pixels, F/2.8 telephoto
dual-lens camera, F/1.8 wide-angle camera, and iOS 10.1 operating system). The smartphone is mounted on a
bracket, set to automatic exposure mode, and taken at a reasonable distance to capture an image of the infected
rice leaves. The phone takes images with a 3,024×4,032-pixel resolution. Figure 2 displays the sample images
for each class with rice blast image in Figure 2(a), the sheath blast, brown spot images in Figures 2(b) and 2(c),
respectively. Figure 2(d) illustrates the healthy rice plant image. Table 1 contains a detailed description of the
dataset.

Three rice diseases were captured with 2,000 images for each class. As a result, 8,000 sample images
were gathered in total, of which 2,000 were free of brown spot, sheath blight, and rice blast. Every image is
saved in the jpeg format and compressed to a standard size of 400×300. Further, 75% of the samples are

selected at random as training sets from the dataset, and the remaining 25% are chosen as testing sets. So, each
class contains 15 numbers of training images and 500 numbers of testing images. In addition, a total of 6,000
training images are considered, along with 2,000 testing images.
2.2. Feature extraction
The goal of feature extraction is to reduce the number of resources necessary to describe a huge set of
data. One of the primary issues with analyzing complicated data is the large number of variables involved.
A large number of variables necessitates a huge amount of memory and compute capacity, and it may also lead
a classification method to overfit to training examples and generalize poorly to new samples. The process of
converting raw data into numerical features that may be processed while retaining the information in the
original data set is referred to as feature extraction [11].
2.2.1. Color feature extraction
The image’s orientation, size, and angle have no bearing on the color feature. It is a typical visual
aspect of the image and is frequently utilized in image recognition. The red green blue (RGB), HSV, and lab
color spaces are employed in this research to extract the color eigenvalues of rice disease. To acquire the
energy, mean, and color set variance in HSV space, along with other color properties, the image of rice disease
with disease spots is first converted from the “RGB” color space to the “HSV” color space. The color
characteristic is then expanded upon by obtaining the third order of color moments corresponding to every
element in lab space: RGB and HSV [12], [13]. The color moment (mean) of the first order depicts the image’s
average brightness. It is described (1).
𝜇𝑗 =
1
𝑁
∑ 𝑃𝑖,𝑗
𝑁
𝑗=1 (1)
The color moment (variance) of second order illustrates the discreteness of the grey level distribution
in the image. It is expressed as underneath (2).
𝜎𝑖 = [
1
𝑁
∑ (𝑝𝑖,𝑗 − 𝜇𝑗)2
𝑁
𝑗=0 ]
1/2
(2)
The color moment of third order describes the asymmetry and skewness of the color components. It is described
as (3):
𝑠𝑖 = [
1
𝑁
∑ (𝑝𝑖,𝑗 − 𝜇𝑗)3
𝑁
𝑗=0 ]
1/3
(3)
where 𝑝𝑖,𝑗 signifies the jth
pixel of the color image’s ith
color component, and N denotes the image’s pixels
number.
2.2.2. Texture feature extraction
The order and organization of an object’s parts can be reflected in its texture. It serves as a crucial
visual component in the image description. It possesses rotation invariance and can compute the statistical
characteristics of several pixel regions [14]–[18]. The gray-level co-occurrence matrix (GLCM) method, which
is the most popular technique for extracting texture features. It may efficiently depict how an image changes
at a specific distance and in a specific direction. Therefore, in this study, texture features are extracted using
the co-occurrence matrix of the grey level. Figure 3 displays the texture-feature extraction effect. Formula (4)
can be used to represent the GLCM (4).
𝑝(𝑎1, 𝑎2) =
≠{[(𝑥1,𝑦1),(𝑥2,𝑦2)]∈𝑆}|𝑓(𝑥1,𝑦1)=𝑎1&𝑓(𝑥2,𝑦2)=𝑎2}
#𝑆
𝑦 (4)
In this method, 𝑓(𝑥, 𝑦) denotes the image itself, S indicates the pixel pair is set with certain spatial
connections in the image, and the expression on the equation's numerator right side indicates the number of
pixel pairs with a spatial connection and a grey value of a1, a2, while the expression on the denominator
indicates the overall pixel pair’s number (# indicates the number of statistical elements).
The following are the recovered common feature parameters based on the GLCM:
a. ASM: It determines the texture's thickness and the homogeneity of the grayscale in the image.

b. Entropy: It exhibits neither uniformity nor complexity in the texture of the image. It is a measurement of
the amount of texture information included in an image.

2.2.3. Shape feature extraction
This study used the standard morphological criteria of the lesions’ area, circularity, complexity, and
number. From there, it came up with two new physical traits, such as the number of lesions, and suggested a
ratio between the size and number of lesions. The “Lesion” area calculation formula is as (9):
𝑆 = ∑ ∑ 𝑓(𝑥, 𝑦)
𝑚
𝑦=1
𝑛
𝑥=1 (9)
here, the binary image function is denoted by 𝑓(𝑥, 𝑦). Circularity (C) denotes the degree of deviation between
the shape of the circle and the lesion area, and the “calculation” formula is described in (10).
𝐶 = 𝑑𝑚𝑎𝑥 − 𝑑𝑚𝑖𝑛 (10)
where dmax − dmin indicates the maximum and minimum diameter of the lesion’s cross-section. The lesions
E complexity is a formula for determining the perimeter of the lesion area per unit area, and it can be written
as (11):
𝐸 =

here, N is the number of rice disease spots present on an infected leaf. The ratio of “lesion area” to the number
of lesions is mentioned as (12).

2.3. S-particle swam optimization
The PSO technique incorporates a velocity update expression that relies on the mode using parameters
from Markov to achieve a balance between local and global search. In general, early-stage particles should
maintain their diversity and independence because this broadens the search space and prevents early
convergence to the local optimum [19]–[22]. All groups might ultimately converge on the most correct particles
and arrive at a more precise answer. These are the velocities and positions of the particles as they have evolved.
Table 2 provides the pseudocode for SPSO.

2.4. DBN classifier
The DBN classification model is introduced after the common DBN model, and RBM’s components are
re-explained in this section. An RBM is a two-layered random-generating neural network. Binary visible units
are present in one layer, whereas binary hidden units are present in the other. A “nonlinear dynamic” system’s
energy function in the Hopfield network was used to construct an energy function that was used to determine the
RBM state. As a result, the RBM model can be easily examined, and the system’s objective function was changed
into an extreme value. Since an RBM is considered a model, its energy function is written as (13):
𝐸(𝑣, ℎ; 𝜃) = − ∑ 𝑤𝑖 𝑗𝑣𝑖ℎ𝑗 − ∑ 𝑏𝑖𝑣𝑖 − ∑ 𝑎𝑗ℎ𝑗
𝑗
𝑖
𝑖,𝑗 (13)
here 𝜃 = (𝑤, 𝑎, 𝑏) indicates the RBM parameter; 𝑤𝑖 𝑗 signifies the relationship value between visible units (v)
and hidden units (h); and 𝑏𝑖 and 𝑎𝑗 indicates bias terms of the visible as well as hidden units. The hidden units’
h conditional distributions and the visible units’ v conditional distributions are written as (14) and (15).
𝑝(ℎ𝑗 = 1
𝑣
⁄ ) =
1
1+𝑒𝑥𝑝 (− ∑ 𝑤𝑖 𝑗𝑣𝑖

(14)
𝑝(𝑣𝑖 = 1
ℎ
⁄ ) =
1
1+𝑒𝑥𝑝 (− ∑ 𝑤𝑖 𝑗ℎ𝑗
𝑗 −𝑎𝑖)
(15)
The RBM’s target function concentrates on finding a way to solve the h and v distribution that makes
them as equal as possible. As a result, we determined their distribution’s Kullback-Leibler (K-L) distance.
Then cut it down. Obtaining the normalizing factor 𝑍(𝜃) will help in calculating the expectation of the joint
probability. is challenging, and its time complexity is 𝑂(2𝑚+𝑛
). As a result, Gibbs sampling was mainly on
reconstructed information. Weights learning is expressed as (16) [23].
∆𝑤𝑖 𝑗 = 𝐸𝑑𝑎𝑡𝑎(𝑣𝑖ℎ𝑗) − 𝐸𝑚𝑜𝑑𝑒𝑙(𝑣𝑖ℎ𝑗) (16)
DBN is a DL neural network made up of one back propagation (BP) layer and three RBM layers as
shown in Figure 4 [24], [25]. The DBN has the benefit that it can extract nonlinear features from visible layer
units of unlabeled training data using hidden layer units. There are two steps to training a DBN. Pretraining is
the first step, where weights for the generative model are created using an unsupervised, greedy, “layer-by-
layer” pretraining process. The second phase is fine-tuning, which uses the gradient descent approach to
increase the discriminant model’s capacity for generalization.

3. RESULTS AND DISCUSSION
3.1. Training and testing parameters
Python 3.6 along with TensorFlow 2.0 and Keras 2.2.4 open-source deep learning frameworks are
used with the Ubuntu 18.04 X64 OS (operating system) to process the images and apply the algorithm. The
influence on accuracy is the key consideration in the detection of rice blasts, sheath blight, and brown spots
using SPSO and DBN. Following the experimental comparison, it was ultimately decided that there were
15 RBM hidden layers, 128 hidden layer nodes, 64 batches, a 0.01 learning rate, a stochastic gradient descent
(SGD) optimizer, and a 0.9 momentum.
3.2. Experiment results
The DBN and SPSO models’ stability and effectiveness, as well as the results of the recognition
process, are validated using the 10-fold cross-validation approach. The model’s accuracy and error recognition
rates are 97.48% and 95.67%, respectively. Table 3 compares the performance of the proposed DBN+SPSO
with existing ML methods such as the random forest model. Moreover, the proposed DBN+SPSO was also
compared with the DL-based convolutional neural network (CNN) and deep belief networks (DBN)+support
vector machine (SVM) models. Here, the proposed DBN+SPSO resulted in superior performance as compared

to the existing ML and DL models. Figure 5(a) displays the accuracy comparison graph for the three models.
It demonstrates the model’s high level of recognition capacity and ensures a low rate of false detections.

4. CONCLUSION
In this paper, a new way of finding rice diseases based on SPSO and DBN was suggested. Data
preparation, the structure of the recognition model, and how the DBN and SPSO implementation technologies
work have all been thoroughly explained. For the SPSO and DBN approaches to effectively detect rice disease
from the ROI that is generated using preprocessing rice disease images, three features (containing the color,
texture, and shape) were extracted. Additionally, many indices were suggested to validate the SPSO and DBN
approaches that have been previously provided. These indices show that the SPSO and DBN approaches
achieve improved recognition and influence and have good anti-interference and resilience. In comparison to
the SVM and CNN models, the new technique has shown improved training performance, a faster accuracy
rate, and improved recognition capability. Though the SPSO and DBN have improved their performance in
rice disease recognition sectors, several issues remain. The first question is how to choose the best weights and
bias factors. The second is how to obtain high-quality samples of rice disease images given the impact of
lighting, foresight, and shooting angle. The final question is how to increase the effectiveness of model training,
the level of recognition, and application capability.
