The growth of abnormal cells in the brain’s tissue causes brain tumors. Brain tumors are considered one of the most dangerous disorders in children and adults. It develops quickly, and the patient’s survival prospects are slim if not appropriately treated. Proper treatment planning and precise diagnoses are essential to improving a patient’s life expectancy. Brain tumors are mainly diagnosed using magnetic resonance imaging (MRI). As part of a convolution neural network (CNN)-based illustration, an architecture containing five convolution layers, five max-pooling layers, a Flatten layer, and two dense layers has been proposed for detecting brain tumors from MRI images. The proposed model includes an automatic feature extractor, modified hidden layer architecture, and activation function. Several test cases were performed, and the proposed model achieved 98.6% accuracy and 97.8% precision score with a low cross-entropy rate. Compared with other approaches such as adjacent feature propagation network (AFPNet), mask region-based CNN (mask RCNN), YOLOv5, and Fourier CNN (FCNN), the proposed model has performed better in detecting brain tumors.

Hybrid model for detection of brain tumor using convolution neural networksCSITiaesprime
The development of aberrant brain cells, some of which may turn cancerous, is known as a brain tumor. Magnetic resonance imaging (MRI) scans are the most common technique for finding brain tumors. Information about the aberrant tissue growth in the brain is discernible from the MRI scans. In numerous research papers, machine learning, and deep learning algorithms are used to detect brain tumors. It takes extremely little time to forecast a brain tumor when these algorithms are applied to MRI pictures, and better accuracy makes it easier to treat patients. The radiologist can make speedy decisions because of this forecast. The proposed work creates a hybrid convolution neural networks (CNN) model using CNN for feature extraction and logistic regression (LR). The pre-trained model visual geometry group 16 (VGG16) is used for the extraction of features. To reduce the complexity and parameters to train we eliminated the last eight layers of VGG16. From this transformed model the features are extracted in the form of a vector array. These features fed into different machine learning classifiers like support vector machine (SVM), naïve bayes (NB), LR, extreme gradient boosting (XGBoost), AdaBoost, and random forest for training and testing. The performance of different classifiers is compared. The CNN-LR hybrid combination outperformed the remaining classifiers. The evaluation measures such as recall, precision, F1-score, and accuracy of the proposed CNN-LR model are 94%, 94%, 94%, and 91% respectively.

Alzheimer's disease (AD) is a brain disease that significantly declines a person's ability to remember and behave normally. By applying several approaches to distinguish between various stages of AD, neuroimaging data has been used to extract different patterns associated with various phases of AD. However, because the brain patterns of older adults and those in different phases are similar, researchers have had difficulty classifying them. In this paper, the 50-layer residual neural network (ResNet) is modified by adding extra convolution layers to make the extracted features more diverse. Besides, the activation function (ReLU) was replaced with (Leaky ReLU) because ReLU takes the negative parts of its input, drops them to zero, and retains the positive parts. These negative inputs may contain useful feature information that could aid in the development of high-level discriminative features. Thus, Leaky ReLU was used instead of ReLU to prevent any potential loss of input information. In order to train the network from scratch without encountering the issue of overfitting, we added a dropout layer before the fully connected layer. The proposed method successfully classified the four stages of AD with an accuracy of 97.49 % and 98 % for precision, recall, and f1-score.

At first, the skull stripping process is proposed to segregate the non-designated regions to extract the designated brain regions. Those resultant brain region images are further subjected to discover the brain tumor.

The results reveal that the proposed method is quite efficient to extract the tumor region. The accuracy rate for segmentation and separation of area of interest in brain tumor reached to 95%. Finally, the significance of the proposed procedure is confirmed using the real image clinical dataset got from ten patients were diagnosed as begin, malignant, and metastatic brain tumors in Al-Yarmouk and Baghdad teaching hospital in Baghdad, Iraq.

Medical images magnetic resonance imaging (MRI) analysis is a very challenging domain especially in the segmentation process for predicting tumefactions with high accuracy. Although deep learning techniques achieve remarkable success in classification and segmentation phases, it remains a rich area to investigate, due to the variance of tumefactions sizes, locations and shapes. Moreover, the high fusion between tumors and their anatomical appearance causes an imprecise detection for tumor boundaries. So, using hybrid segmentation technique will strengthen the reliability and generality of the diagnostic model. This paper presents an automated hybrid segmentation approach combined with convolution neural network (CNN) model for brain tumor detection and prediction, as one of many offered functions by the previously introduced IoMT medical service “DiaMe”.

A modified residual network for detection and classification of Alzheimer’s ...IJECEIAES
Alzheimer's disease (AD) is a brain disease that significantly declines a person's ability to remember and behave normally. By applying several approaches to distinguish between various stages of AD, neuroimaging data has been used to extract different patterns associated with various phases of AD. However, because the brain patterns of older adults and those in different phases are similar, researchers have had difficulty classifying them. In this paper, the 50-layer residual neural network (ResNet) is modified by adding extra convolution layers to make the extracted features more diverse. Besides, the activation function (ReLU) was replaced with (Leaky ReLU) because ReLU takes the negative parts of its input, drops them to zero, and retains the positive parts. These negative inputs may contain useful feature information that could aid in the development of high-level discriminative features. Thus, Leaky ReLU was used instead of ReLU to prevent any potential loss of input information. In order to train the network from scratch without encountering the issue of overfitting, we added a dropout layer before the fully connected layer. The proposed method successfully classified the four stages of AD with an accuracy of 97.49 % and 98 % for precision, recall, and f1-score.

Medical images magnetic resonance imaging (MRI) analysis is a very challenging domain especially in the segmentation process for predicting tumefactions with high accuracy. Although deep learning techniques achieve remarkable success in classification and segmentation phases, it remains a rich area to investigate, due to the variance of tumefactions sizes, locations and shapes.

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.

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.

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

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.

system is designed to enhance power quality. Our approach employs fuzzy
logic in the direct power control (DPC) of a three-phase voltage source

IEEE standards to evaluate the system's grid compatibility.

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.

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.

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.
An efficient security framework for intrusion detection and prevention in int...IJECEIAES
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%.

The growth of abnormal cells in the brain’s tissue causes brain tumors. Brain
tumors are considered one of the most dangerous disorders in children and
adults. It develops quickly, and the patient’s survival prospects are slim if
not appropriately treated. Proper treatment planning and precise diagnoses
are essential to improving a patient’s life expectancy. Brain tumors are
mainly diagnosed using magnetic resonance imaging (MRI). As part of a
convolution neural network (CNN)-based illustration, an architecture
containing five convolution layers, five max-pooling layers, a Flatten layer,
and two dense layers has been proposed for detecting brain tumors from
MRI images. The proposed model includes an automatic feature extractor,
modified hidden layer architecture, and activation function. Several test cases
were performed, and the proposed model achieved 98.6% accuracy and
97.8% precision score with a low cross-entropy rate. Compared with other
approaches such as adjacent feature propagation network (AFPNet), mask
region-based CNN (mask RCNN), YOLOv5, and Fourier CNN (FCNN), the
proposed model has performed better in detecting brain tumors.

1. INTRODUCTION
The human body is made of millions of cells, and the brain is an essential part of the human body. A
brain tumor is caused by abnormal cells in the brain’s tissue. It is considered one of the world’s deadliest
diseases [1], [2] due to its escalating impact and fatality rate in all age categories. It is India’s second-leading
cause of cancer [3]. According to the American Cancer Society’s most recent report, around 24,000 people in
the United States were infected with brain tumors in 2020, with an estimated 19,000 deaths due to the
increased use of technology such as cell phones and tablets [4], [5]. Approximately 120 varieties of tumors
have been discovered too far, and they all arise in various shapes and sizes, making diagnosis more
challenging [6]–[8]. Medical imaging modalities like positron emission tomography (PET), computed
tomography (CT), magnetic resonance imaging (MRI), and magnetoencephalography (MEG) have been
utilized to diagnose brain irregularities for a long time [9], [10]. The MRI multimodality imaging technique is
the most common and efficient technology routinely used to diagnose brain tumors because of its capacity to
distinguish between structure and tissue based on contrast levels [11], [12]. MRI anomaly detection is now

primarily manual, and doctors must spend significant time discovering and segmenting the tumor for therapy
and surgery [13], [14]. This manual procedure is also prone to errors and can endanger one’s life.
Researchers have begun to examine various machine learning and deep learning techniques for computer-
based tumor diagnosis and segmentation to address these challenges.
Deep learning is a machine learning subfield widely used to develop a semi-automatic, automatic, or
hybrid model to detect and segment tumors in less time [15]. Radiologists can make a more accurate
prognosis and increase the odds of long-term survival if a brain tumor is discovered early [10]. The tumor’s
shifting appearance, position, form, and size [16] remains a complex process. There has already been a lot of
work done to assist doctors, patients, and researchers. Many computers aided diagnostic (CAD) systems have
been created to detect and classify brain anomalies [17] automatically, but they still perform with poor
accuracy [18]. Several articles have been published without highlighting the flaws in previous work or
providing any significant insight into future directions. Interoperability is lacking in most hybrid models,
while gradient vanishing is a concern in deep learning models. Similarly, there is a lack of uniformity in data
preprocessing.
This article aims to process the images from MRI and detect tumors in the brain by solving previous
issues. Image enhancement, rebuilding, and estimation extraction techniques have been applied to enhance
image quality while preparing the dataset. The image digitization process and picture upgrade techniques
handle defective images. A modified CNN has been applied to take an MRI scan image of the brain as input,
detect the tumor, and give the result as output. The network contains five convolution layers, five
max-pooling layers, a Flatten layer, multiple hidden layers, and two dense layers. A modified recto-triangular
architecture has been utilized in the hidden layer that enhances the probability distribution. The model’s
accuracy has been evaluated and compared with state-of-the-art techniques. The model has performed better
than other approaches in detecting brain tumors from MRI images.
2. RELATED WORKS
Image detection plays a crucial role in analyzing brain tumors using MRI images. Many methods for
detecting brain tumors from MRI images have been proposed. In the method presented by Kumar et al. [19],
brain tumors were predicted using a fully convolutional neural network (FCN) from MRI images.
Derikvand et al. [20] presented an approach based on neural convolution. The method used glioma
brain tumor detection networks in MR imaging. The proposed process was a hybrid, multiple CNN
architectures using local and global brain tissue knowledge to predict each pixel’s label, improving results.
CNN was used for image segmentation and detection by Hemanth et al. [21]. It explicitly pulled
features from images with the least amount of preprocessing. LinkNet was employed. The architecture of a
neural network was designed to conduct semantic segmentation and detection. The LinkNet network blocks
of encoders and decoders were responsible for breaking and rebuilding the image until it was routed through
a few final levels of convolution. root mean square error (RMSE), recall, sensitivity, precision, F-score
specificity, and percentage mean error (PME) evaluated the suggested CNN’s performance.
Hossain’s methodology [22] began with the input image’s skull striping, which removed the skull
part from the MRI images. The fuzzy C-means clustering algorithm was used to detect the filtered image.
Texture-based and statistical-based features were extracted from the images. The extracted features were fed
into a CNN model. The model’s accuracy for brain tumor prediction was high, but the computational time
was much longer than other models.
Minz et al. [23] proposed one method that extracted characteristics using the gray level co-occurrence
matrix methodology. An image’s texture was defined by calculating specified spatial relationships that
appeared in an image. Gray level co-occurrence matrix was built, and this matrix extracted statistical
measurements. The classification was done with the AdaBoost classifier, and the proposed system attained an
accuracy of 89.90%.
Gurbin et al. [24] proposed a method using discrete wavelet transform levels (DWT) and continuous
wavelet transform levels (CWT). Support vector machines (SVM) were utilized to identify benign,
malignant, or healthy brains. The research suggested that CWT performs better than DWT in computation.
Chander et al. [25] proposed a strategy to detect afflicted brain tissues using the grade 4 gradient
boosting machine (GBM). The retrieved properties of Bayesian naive were used to classify them. This
method yielded an accuracy of 83.33%. The MRI image was initially fed into the algorithm, which filtered it
to smooth it out and remove noise. The next step was to mask the filtered image to remove brain tissues from
the skull. Finally, the acquired features were sent into an SVM classifier, which determined whether the
image was malignant or not.
After examining many algorithms for detecting brain tumors, we found that most algorithms
required a long computational time, while cheap computational time methods could not provide greater

accuracy. Every classifier requires rectifying the predecessor’s flaws, and boosting is sensitive to outliers. As
a result, the technique is overly reliant on outliers. Another downside is that scaling up the process is nearly
impossible because each estimator is based on the accuracy of preceding predictors. As a result, we intended
to propose an approach that could provide excellent accuracy.
3. BRAIN TUMOR DETECTION PROCESS
3.1. Data collection
A dataset containing 30,000 images was collected to train the deep learning model. The dataset
contained two classes: fresh MRI images of the brain and the images with a brain tumor. The collected data
contains 15,000 images of healthy brains and 15,000 images of brain tumors. For testing the dataset, related
images were collected from Google. There are 4,400 brain images that were taken without a tumor, and
3,200 images were taken with a tumor. A small part of the collected images is shown in Figure 1. For
comparison purpose, the BRATS datasets [26] (BRATS_2018, BRATS_2019, BRATS_2020) were utilized.
Figure 1. A part of collected images
3.2. Data preprocessing
The preprocessing step aims to increase picture quality, data cleansing, and contrast-enhancing. The
median filter filters out the noise and retrieves valuable data. Median filtering is a nonlinear approach used to
retain sharp features in MRI images. In this work, an MRI image was preprocessed by converting the picture
to greyscale and using a 33 median filter to eliminate noise, which enhanced image quality using (1).
𝑓(𝑥, 𝑦) = 𝑚𝑒𝑑𝑖𝑎𝑛(𝑠,𝑡)𝑒𝑆𝑥𝑦{𝑔(𝑠, 𝑡)} (1)
A high pass filter was used to locate edges in the acquired MRI image. The edge-identified MRI
image was combined with the original image to obtain the enhanced image. The dataset was enlarged using
the data augmentation process to keep a strategic distance from overfitting. The dataset was augmented using
four distinct tactics: rotate left -90 degrees, rotate left -180 degrees, rotate left -270 degree, and flip every
image once.
3.3. CNN model architecture
CNN was utilized to detect brain cancers using MR images in this study. CNN is an artificial neural
network (ANN) designed to analyze image pixels and extract meaningful images. CNNs are used in image and
video recognition [27]–[29], natural language processing, and artificial intelligence. In this study, the proposed
architecture contains an input layer, five convolutions, five max pooling, one flattens, fully connected, or
concealed, and two dense layers. The basic architecture of the proposed CNN is depicted in Figure 2.
The input layer is usually a pixel-filled image, and to construct a convolution layer, a feature map is
built and slid over these pixels. The pooling stage minimizes the number of features and increases the
correlation between proximity pixels. The suggested method uses the max-pooling methodology to
downsample images and extract essential features, such as edges. In this article, a max-pooling approach is
applied after each convolution layer. In the convolution 2D layer, the input images are scaled to 300*300
pixels. The rectified linear unit (ReLU) activation function is used in each convolution layer. The first
4. ISSN: 2088-8708

convolution layer uses sixteen feature maps or filters and a 3×3 feature detector matrix. With the same 3×3
feature detector matrix size, the number of feature maps or filters in the second convolution layer was
increased to 32. The max-pooling layer uses a 2×2 feature extraction matrix after the convolution layer. After
all the convolutions and max pooling, the resultant matrices are broken down into a flatten layer or a single
column with all the pixel values. This flattening layer is then utilized to input the hidden layer of the
following artificial neural network. Hidden layers are followed by two dense layers, which process the output
for the network. This research compares the assessment score of the proposed recto-triangular design for the
hidden layer to triangular and rectangular architectures shown in Figures 3(a) to (c).

3.4. Triangular architecture
The modified triangular architecture comprises 256 nodes in the first hidden layer, 512 nodes in the
second hidden layer, and the number of nodes drops to take the shape of a triangle from the third layer to the
seventh layer. The hidden layers include 256, 512, 256, 128, 64, 32, and 16 nodes. The ReLU activation
function activates all the seven hidden levels. The output layer employs the SoftMax activation function to
simplify modeling probability distributions. Figure 3(a) depicts the architecture.
3.5. Rectangular architecture
There are six hidden layers in the rectangular architecture. Because of the shape, the design is
rectangular architecture, which comprises six levels with similar nodes in individual layers. Figure 3(b)
illustrates the architecture. The number of hidden layers employed in this article for the rectangular design is
6, with each layer having 256 nodes. Each hidden layer utilizes the ReLU activation function, but only the
output layer uses the SoftMax activation function.
3.6. Proposed recto-triangular architecture
The recto-triangular, a combination of rectangular and triangular architecture, is proposed in this
article. The architecture is made up of six layers in the hidden layer. Figure 3(c) depicts the proposed
recto-triangular architecture’s shape and layers. The first, second, third, fourth, fifth, and sixth hidden layers
contain 512, 256, 128, 128, 256, and 512 nodes. The number of nodes in the prevalent structure of the hidden
layer drops at first, then rises till it reaches the output layer. ReLU is employed to activate all six hidden
layers. The output layer uses a SoftMax activation function to represent the probability allocation accurately.
4. RESULT AND ANALYSIS
4.1. Training the model
For evaluating the performance of the training period, a cross-validation approach was used in
training. The data was trained using two separate approaches. The first technique separated the data into ten
equivalent areas to ensure that each part was equally available. Another strategy was employed to divide the
data into ten equal portions, each containing only data from one participant. As a result, the individual
package contained data from multiple subjects regardless of the brain tumor class selected by subject-wise
cross-validation. This method evaluated a network’s ability to generalize medical diagnoses. In clinical
practice, the capacity for generalization indicates that a diagnosis can be predicted based on information
acquired from participants with no results during training. The focal loss function (2) was operated to tackle
class inequality issues.
𝐹𝑜𝑐𝑎𝑙 = −(1 − 𝑃)𝛾 ∑ 𝑙𝑛 ∗ ln(𝑃𝑛) …
𝑛
𝑛−1 (2)
The focal loss was expressed as pixel weights, where n is the number of classes, indicating that the
pixels belong to the kth class, Pn denotes the anticipated probability, and p denotes a high probability that is
more difficult to identify accurately. The focus loss function value is ten, and weights are assigned to classify
pixels effectively.
4.2. Performance metrics
With the validation findings and four assessment parameters, we created our model. Correct values
are true negative (TN) and true positive (TP), where TP indicates accurately classified aberrant brain images
and TN indicates accurately classified standard brain images. False-negative (FN) and false-positive (FP) are
inaccurate classifications, where FP indicates inaccurate typical brain imaging and FN indicates inaccurate
pathological brain images. Our suggested model’s accuracy, dice score/F1, recall, and precision is evaluated
using (3) to (6).

4.3. Performance measurement
The MRI data were separated into validation, testing, and training. During training, the suggested
framework utilized a minibatch of size 16. An ‘Adam’ optimizer with a learning rate of 0.001 was used, and
the data was shuffled in each epoch. The performance was assessed using four performance matrices
(accuracy, precision, dice score, and recall). The suggested model took 31.53 minutes to train, with
47.82 seconds average training time per epoch.
Figure 4 shows training and validation loss and accuracy, whereas 4(a) depicts the training and
validation accuracy with the increasing number of epochs. Figure 4(b) depicts the loss curve. From the
figure, it is noticeable that the network quickly began learning from MRI images. From a test dataset of
7,600 images, we calculated precision, recall, and F1-score. Some resulting images of tumor detection by the
proposed method are shown in Figure 5.

4.4. Comparison among architectures
Triangular, rectangular, and recto-triangular architecture are covered in this study. The same dataset
was used to train and evaluate all three architectures. The rectangular architecture, which has six hidden layers,
performed a training accuracy of 97.9% and a precision of 91.2%. In contrast, the triangular architecture with
seven hidden layers performed a training accuracy of 97.5%, which was 0.4% less than the rectangular
architecture. Still, the triangular architecture’s precision score was 2.6% greater than the rectangular architecture.
Figure 6 shows the comparison of three different architectures. Figure 6 shows that the proposed
recto-triangular architecture has achieved a 98.6% training and 97.8% precision score, which is the best
compared to the other two. From the evaluation, it can be concluded that the proposed architecture provides
satisfactory results and performs better in detecting brain tumors.
4.5. Comparison among several approaches and datasets
The suggested model was compared to some existing approaches in terms of performance. As a
baseline, the suggested technique was compared to FCNN, mask RCNN, YOLOv5, and AFPNet. Based on
the prepared dataset, Table 1 shows a detailed comparison. The findings show that the proposed architecture

performs much better than prior research investigations. The generated model dominates and surpasses the
current state-of-the-art model. The proposed model’s performance was measured on the existing brain tumor
dataset BRATS 2018, 2019, and 2020. Table 2 shows the model’s performance on BRATS datasets.

5. CONCLUSION
A modified architecture has been proposed in this article that takes advantage of the processed MRI
dataset and proposed recto-triangular architecture in the hidden layer for brain tumor detection. The proposed
CNN model may perform better than human observers by focusing on a portion of the brain image near the
tumor tissue. The proposed preprocessing techniques remove many irrelevant pixels from the images to
reduce computing time and capacity. Compared to state-of-the-art alternatives, the proposed model with the
proposed hidden layer architecture and the processed dataset have performed better. In the future, we plan to
improve the filters to enhance accuracy.
