This is a deep learning presentation based on Deep Neural Network. It reviews the deep learning concept, related works and specific application areas.It describes a use case scenario of deep learning and highlights the current trends and research issues of deep learning
Deep learning is a type of machine learning that uses neural networks inspired by the human brain. It has been successfully applied to problems like image recognition, speech recognition, and natural language processing. Deep learning requires large datasets, clear goals, computing power, and neural network architectures. Popular deep learning models include convolutional neural networks and recurrent neural networks. Researchers like Geoffry Hinton and companies like Google have advanced the field through innovations that have won image recognition challenges. Deep learning will continue solving harder artificial intelligence problems by learning from massive amounts of data.
- The document introduces artificial neural networks, which aim to mimic the structure and functions of the human brain.
- It describes the basic components of artificial neurons and how they are modeled after biological neurons. It also explains different types of neural network architectures.
- The document discusses supervised and unsupervised learning in neural networks. It provides details on the backpropagation algorithm, a commonly used method for training multilayer feedforward neural networks using gradient descent.
In machine learning, a convolutional neural network is a class of deep, feed-forward artificial neural networks that have successfully been applied fpr analyzing visual imagery.
[PR12] You Only Look Once (YOLO): Unified Real-Time Object DetectionTaegyun Jeon
The document summarizes the You Only Look Once (YOLO) object detection method. YOLO frames object detection as a single regression problem to directly predict bounding boxes and class probabilities from full images in one pass. This allows for extremely fast detection speeds of 45 frames per second. YOLO uses a feedforward convolutional neural network to apply a single neural network to the full image. This allows it to leverage contextual information and makes predictions about bounding boxes and class probabilities for all classes with one network.
Machine learning and its applications was a gentle introduction to machine learning presented by Dr. Ganesh Neelakanta Iyer. The presentation covered an introduction to machine learning, different types of machine learning problems including classification, regression, and clustering. It also provided examples of applications of machine learning at companies like Facebook, Google, and McDonald's. The presentation concluded with discussing the general machine learning framework and steps involved in working with machine learning problems.
This document summarizes Melanie Swan's presentation on deep learning. It began with defining key deep learning concepts and techniques, including neural networks, supervised vs. unsupervised learning, and convolutional neural networks. It then explained how deep learning works by using multiple processing layers to extract higher-level features from data and make predictions. Deep learning has various applications like image recognition and speech recognition. The presentation concluded by discussing how deep learning is inspired by concepts from physics and statistical mechanics.
Deep learning and neural networks are inspired by biological neurons. Artificial neural networks (ANN) can have multiple layers and learn through backpropagation. Deep neural networks with multiple hidden layers did not work well until recent developments in unsupervised pre-training of layers. Experiments on MNIST digit recognition and NORB object recognition datasets showed deep belief networks and deep Boltzmann machines outperform other models. Deep learning is now widely used for applications like computer vision, natural language processing, and information retrieval.
The document discusses the K-nearest neighbors (KNN) algorithm, a simple machine learning algorithm used for classification problems. KNN works by finding the K training examples that are closest in distance to a new data point, and assigning the most common class among those K examples as the prediction for the new data point. The document covers how KNN calculates distances between data points, how to choose the K value, techniques for handling different data types, and the strengths and weaknesses of the KNN algorithm.
Residual neural networks (ResNets) solve the vanishing gradient problem through shortcut connections that allow gradients to flow directly through the network. The ResNet architecture consists of repeating blocks with convolutional layers and shortcut connections. These connections perform identity mappings and add the outputs of the convolutional layers to the shortcut connection. This helps networks converge earlier and increases accuracy. Variants include basic blocks with two convolutional layers and bottleneck blocks with three layers. Parameters like number of layers affect ResNet performance, with deeper networks showing improved accuracy. YOLO is a variant that replaces the softmax layer with a 1x1 convolutional layer and logistic function for multi-label classification.
Federated Learning makes it possible to build machine learning systems without direct access to training data. The data remains in its original location, which helps to ensure privacy, reduces network communication costs, and taps edge device computing resources. The principles of data minimization established by the GDPR, and the growing prevalence of smart sensors make the advantages of federated learning more compelling. Federated learning is a great fit for smartphones, industrial and consumer IoT, healthcare and other privacy-sensitive use cases, and industrial sensor applications.
We’ll present the Fast Forward Labs team’s research on this topic and the accompanying prototype application, “Turbofan Tycoon”: a simplified working example of federated learning applied to a predictive maintenance problem. In this demo scenario, customers of an industrial turbofan manufacturer are not willing to share the details of how their components failed with the manufacturer, but want the manufacturer to provide them with a strategy to maintain the part. Federated learning allows us to satisfy the customer's privacy concerns while providing them with a model that leads to fewer costly failures and less maintenance downtime.
We’ll discuss the advantages and tradeoffs of taking the federated approach. We’ll assess the state of tooling for federated learning, circumstances in which you might want to consider applying it, and the challenges you’d face along the way.

This presentation introduces naive Bayesian classification. It begins with an overview of Bayes' theorem and defines a naive Bayes classifier as one that assumes conditional independence between predictor variables given the class. The document provides examples of text classification using naive Bayes and discusses its advantages of simplicity and accuracy, as well as its limitation of assuming independence. It concludes that naive Bayes is a commonly used and effective classification technique.
It’s long ago, approx. 30 years, since AI was not only a topic for Science-Fiction writers, but also a major research field surrounded with huge hopes and investments. But the over-inflated expectations ended in a subsequent crash and followed by a period of absent funding and interest – the so-called AI winter. However, the last 3 years changed everything – again. Deep learning, a machine learning technique inspired by the human brain, successfully crushed one benchmark after another and tech companies, like Google, Facebook and Microsoft, started to invest billions in AI research. “The pace of progress in artificial general intelligence is incredible fast” (Elon Musk – CEO Tesla & SpaceX) leading to an AI that “would be either the best or the worst thing ever to happen to humanity” (Stephen Hawking – Physicist).
What sparked this new Hype? How is Deep Learning different from previous approaches? Are the advancing AI technologies really a threat for humanity? Let’s look behind the curtain and unravel the reality. This talk will explore why Sundar Pichai (CEO Google) recently announced that “machine learning is a core transformative way by which Google is rethinking everything they are doing” and explain why "Deep Learning is probably one of the most exciting things that is happening in the computer industry” (Jen-Hsun Huang – CEO NVIDIA).
Either a new AI “winter is coming” (Ned Stark – House Stark) or this new wave of innovation might turn out as the “last invention humans ever need to make” (Nick Bostrom – AI Philosoph). Or maybe it’s just another great technology helping humans to achieve more.
Here are the key calculations:
1) Probability that persons p and q will be at the same hotel on a given day d is 1/100 × 1/100 × 10-5 = 10-9, since there are 100 hotels and each person stays in a hotel with probability 10-5 on any given day.
2) Probability that p and q will be at the same hotel on given days d1 and d2 is (10-9) × (10-9) = 10-18, since the events are independent.

End-to-end deep auto-encoder for segmenting a moving object with limited tra...IJECEIAES
The document proposes two end-to-end deep auto-encoder approaches for segmenting moving objects from surveillance videos when limited training data is available. The first approach uses transfer learning with a pre-trained VGG-16 model as the encoder and its transposed architecture as the decoder. The second approach uses a multi-depth auto-encoder with convolutional and upsampling layers. Both approaches apply data augmentation techniques like PCA and traditional methods to increase the training data size. The models are trained and evaluated on the CDnet2014 dataset, achieving better performance than other models trained with limited data.
MULTI-LEVEL FEATURE FUSION BASED TRANSFER LEARNING FOR PERSON RE-IDENTIFICATIONgerogepatton
Most of the currently known methods treat person re-identification task as classification problem and used commonly neural networks. However, these methods used only high-level convolutional feature or to express the feature representation of pedestrians. Moreover, the current data sets for person reidentification is relatively small. Under the limitation of the number of training set, deep convolutional networks are difficult to train adequately. Therefore, it is very worthwhile to introduce auxiliary data sets help training. In order to solve this problem, this paper propose a novel method of deep transfer learning, and combines the comparison model with the classification model and multi-level fusion of the
convolution features on the basis of transfer learning. In a multi-layers convolutional network, the characteristics of each layer of network are the dimensionality reduction of the previous layer of results, but the information of multi-level features is not only inclusive, but also has certain complementarity. We can using the information gap of different layers of convolutional neural networks to extract a better feature expression. Finally, the algorithm proposed in this paper is fully tested on four data sets (VIPeR, CUHK01, GRID and PRID450S). The obtained re-identification results prove the effectiveness of the algorithm.

IRJET- Automated Detection of Diabetic Retinopathy using Compressed SensingIRJET Journal
This document describes a proposed method for automated detection of diabetic retinopathy using compressed sensing. It begins with an abstract that outlines the goal of identifying retinal diseases like diabetic retinopathy using image processing techniques. It then provides details on the proposed method, which involves preprocessing retinal images through steps like color conversion, filtering, and morphological operations. Features are then extracted using compressed sensing before classification of diabetic retinopathy. The method aims to allow early detection of retinal diseases to minimize vision damage.

A new approachto image classification based on adeep multiclass AdaBoosting e...IJECEIAES
In recent years, deep learning methods have been developed in order to solve the problems. These methods were effective in solving complex problems. Convolution is one of the learning methods. This method is applied in classifying and processing of images as well. Hybrid methods are another multi-component machine learning method. These methods are categorized into independent and dependent types. Ada-Boosting algorithm is one of these methods. Today, the classification of images has many applications. So far, several algorithms have been presented for binary and multi-class classification. Most of the above-mentioned methods have a high dependence on the data. The present study intends to use a combination of deep learning methods and associated hybrid methods to classify the images. It is presumed that this method is able to reduce the error rate in images classification. The proposed algorithm consists of the Ada-Boosting hybrid method and bi-layer convolutional learning method. The proposed method was analyzed after it was implemented on a multi-class Mnist data set and displayed the result of the error rate reduction. The results of this study indicate that the error rate of the proposed method is less than Ada-Boosting and convolution methods. Also, the network has more stability compared to the other methods.

The 21st-century skills needed to face the speed of understanding technology. Such as critical thinking in computer vision and robotics literacy, any student is hampered by the programming that is considered complicated. This study aims at the improvement of student embedded system programming competency with computer vision and mobile robotics integration approach. This method is proposed to attract the students to learn about embedded system programming by delivering integration between computer vision and robotics using the P-D controller since both of the fields are closely related. In this paper, the researcher described computer vision programming to get the data of captured images through the camera stream and then delivered the data into an embedded system to make the decision of robot movement. The output of this study is the improvement of a student’s ability to make an application to integrate a sensor system using a camera and the mobile robot running follow the line. The result of the test shows that the integration method between computer vision and robotics can improve the student’s programming comprehension by 40%. Based on the Feasibility test survey, it can be interpreted that from the whole assessment after being converted to qualitative data, all aspects of the learning stages of programming application tested with the integration of computer vision and robotics fall into the very feasible category for used with a percentage of feasibility by 77.44%.
IRJET- Deep Learning Techniques for Object DetectionIRJET Journal

Content-based image retrieval (CBIR) uses the content features for
retrieving and searching the images in a given large database. Earlier,
different hand feature descriptor designs are researched based on cues that
are visual such as shape, colour, and texture used to represent these images.
Although, deep learning technologies have widely been applied as an
alternative to designing engineering that is dominant for over a decade. The
features are automatically learnt through the data. This research work
proposes integrated dual deep convolutional neural network (IDD-CNN),
IDD-CNN comprises two distinctive CNN, first CNN exploits the features
and further custom CNN is designed for exploiting the custom features.
Moreover, a novel directed graph is designed that comprises the two blocks
i.e. learning block and memory block which helps in finding the similarity
among images; since this research considers the large dataset, an optimal
strategy is introduced for compact features. Moreover, IDD-CNN is
evaluated considering the two distinctive benchmark datasets the oxford
dataset considering mean average precision (mAP) metrics and comparative
analysis shows IDD-CNN outperforms the other existing model.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

NON LINEARITY (RELU)
ReLU stands for Rectified Linear Unit for a non-linear
operation. The output is ƒ(x) = max(0,x).
Why ReLU is important : ReLU’s purpose is to introduce non-
linearity in our ConvNet. Since, the real world data would want
our ConvNet to learn would be non-negative linear values.

POOLING LAYER
Pooling layers section would reduce the number of parameters when
the images are too large.
Pooling layer consider a block of input data and simply pass on
maximum value
Hence it reduces the size of the input and require no added
parameters

FLATTENING
After finishing the previous two steps, we're supposed to have a pooled feature
map by now. As the name of this step implies, we are literally going to flatten
our pooled feature map into a column like in the image below.

FLATTENING
The reason we do this is that we're going to need to insert this data into
an artificial neural network later on.

Output layer
After multiple layers of convolution and padding.
output should be in the form of a class.
The convolution and pooling layers would only be able to extract features
and reduce the number of parameters from the original images.
However, to generate the final output we need to apply a fully connected
layer to generate an output equal to the number of classes we need.
Thus the output layer give the classified images.
38. Obtained outcome
• Image which are classified with its name.
• The probability of image to be in the other class.

FUTURE SCOPE
Image can be classified and keep in separate folders.
Automatic face recognition and object recognition can be used for
classifying the images automatically.
B.Tech Bachelors Research project : 2015-2019
Implemented an image classifier using convolutional
neural network, which is more efficient for image
classification when comparing to the other methods.
It is usefully for classifying larger number of image with
in short time.
