CNN has become an important part of deep learning networks. It has become crucial to get the in-depth knowledge on CNN. This ppt gives a brief overview on CNN.
Convolutional neural networks (CNNs) are a type of neural network designed to process images. CNNs use a series of convolution and pooling layers to extract features from images. Convolution multiplies the image with filters to produce feature maps, while pooling reduces the size of the representation to reduce computation. This process allows the network to learn increasingly complex features from the input image and classify it. CNNs have applications in areas like facial recognition, document analysis, and image classification.

A Convolutional Neural Network (CNN) is a type of neural network that can process grid-like data like images. It works by applying filters to the input image to extract features at different levels of abstraction. The CNN takes the pixel values of an input image as the input layer. Hidden layers like the convolution layer, ReLU layer and pooling layer are applied to extract features from the image. The fully connected layer at the end identifies the object in the image based on the extracted features. CNNs use the convolution operation with small filter matrices that are convolved across the width and height of the input volume to compute feature maps.

A convolutional neural network (CNN, or ConvNet) is a class of deep, feed-forward artificial neural networks that has Successfully been applied to analyzing visual imagery
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.
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.
The document summarizes the Transformer neural network model proposed in the paper "Attention is All You Need". The Transformer uses self-attention mechanisms rather than recurrent or convolutional layers. It achieves state-of-the-art results in machine translation by allowing the model to jointly attend to information from different representation subspaces. The key components of the Transformer include multi-head self-attention layers in the encoder and masked multi-head self-attention layers in the decoder. Self-attention allows the model to learn long-range dependencies in sequence data more effectively than RNNs.

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.
Machine Learning - Convolutional Neural NetworkRichard Kuo
The document provides an overview of convolutional neural networks (CNNs) for visual recognition. It discusses the basic concepts of CNNs such as convolutional layers, activation functions, pooling layers, and network architectures. Examples of classic CNN architectures like LeNet-5 and AlexNet are presented. Modern architectures such as Inception and ResNet are also discussed. Code examples for image classification using TensorFlow, Keras, and Fastai are provided.
The document discusses the BERT model for natural language processing. It begins with an introduction to BERT and how it achieved state-of-the-art results on 11 NLP tasks in 2018. The document then covers related work on language representation models including ELMo and GPT. It describes the key aspects of the BERT model, including its bidirectional Transformer architecture, pre-training using masked language modeling and next sentence prediction, and fine-tuning for downstream tasks. Experimental results are presented showing BERT outperforming previous models on the GLUE benchmark, SQuAD 1.1, SQuAD 2.0, and SWAG. Ablation studies examine the importance of the pre-training tasks and the effect of model size.
The document summarizes the Batch Normalization technique presented in the paper "Batch Normalization: Accelerating Deep Network Training by Reducing Internal Covariate Shift". Batch Normalization aims to address the issue of internal covariate shift in deep neural networks by normalizing layer inputs to have zero mean and unit variance. It works by computing normalization statistics for each mini-batch and applying them to the inputs. This helps in faster and more stable training of deep networks by reducing the distribution shift across layers. The paper presented ablation studies on MNIST and ImageNet datasets showing Batch Normalization improves training speed and accuracy compared to prior techniques.
GoogLeNet introduced several key insights for designing efficient deep learning networks:
1. Exploit local correlations in images by concatenating 1x1, 3x3, and 5x5 convolutions along with pooling.
2. Decrease dimensions before expensive convolutions using 1x1 convolutions for dimension reduction.
3. Stack inception modules upon each other, occasionally inserting max pooling layers, to allow tweaking each module.
4. Counter vanishing gradients with intermediate losses added to the total loss for training deep networks.
5. End with a global average pooling layer instead of fully connected layers to avoid overfitting.
This document discusses convolutional neural networks (CNNs). It explains that CNNs were inspired by research on the human visual system and take a similar approach to teach computers to identify objects in images. The document outlines the key components of CNNs, including convolutional and pooling layers to extract features from images, as well as fully connected layers to classify objects. It also notes that CNNs take pixel data as input and use many examples to generalize and make predictions, similar to how humans learn visual recognition.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
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. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
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.

6. Traditional Neural Network vs. Convolutional Neural
Network
Salient points:
• Spatial relation between features in image is not considered in NN.
• NN needs huge data to prevent overfitting!
• NN is not feasible for large images!
• In order to perform Computer Vision operations on large images, convolution
operation plays an important role.
• Thus, CNNs are fundamentally important.

32. Foundation of Convolutional Neural Networks
Padding
Image * Filter = Output Image
6 x 6 3 x 3 4 x 4
𝑛 ∗ 𝑛 𝑓 ∗ 𝑓 𝑛𝑜𝑢𝑡 ∗ 𝑛𝑜𝑢𝑡
using 𝑛𝑜𝑢𝑡 = 𝑛 − 𝑓 + 1
Shortcoming of this technique:
1) Output goes on shrinking as the number of layers increase.
2) Information from boundary of the image remains unused.
Solution is Zero padding around the edges of the image!
33. Foundation of Convolutional Neural Networks
Padding
If Image is 6 x 6
𝑛𝑜𝑢𝑡 = 𝑛 − 𝑓 + 1
= 6 − 3 + 1
= 4
Thus, Output Image = 4 x 4
36. Foundation of Convolutional Neural Networks
Padding
How much to pad?
1) Valid = no padding.
Follows the formula 𝑛𝑜𝑢𝑡 = 𝑛 − 𝑓 + 1.
2) Same = Output dimension is Same as input.
Follows the formula 𝑛𝑜𝑢𝑡 = 𝑛 + 2𝑝 − 𝑓 + 1.
To keep Output size same as input size: 𝑛 = 𝑛 + 2𝑝 − 𝑓 + 1
𝑝 =
𝑓−1
2
Thus, filters are generally odd.
48. Foundation of Convolutional Neural Networks
Summary of Convolution
For an 𝑛 ∗ 𝑛 image and filter 𝑓 ∗ 𝑓 with padding 𝑝 and a stride of 𝑠 pixels,
Output image dimension is given by:
𝑛 + 2𝑝 − 𝑓
𝑠
+ 1 ∗
𝑛 + 2𝑝 − 𝑓
𝑠
+ 1
49. Convolution vs. Cross-correlation
Convolution involves: flip on axes -> multiply -> sum
Cross-correlation involves: multiply -> sum
In CNNs, the process is cross-correlation but is referred to as convolution by
convention.
76. Summary of Convolution with Multiple filters
For an 𝑛 ∗ 𝑛 ∗ 𝑐 image and 𝑁 filters each 𝑓 ∗ 𝑓 ∗ 𝑐 with padding 𝑝 and a stride of
𝑠 pixels,
Output image dimension is given by:
𝑛 + 2𝑝 − 𝑓
𝑠
+ 1 ∗
𝑛 + 2𝑝 − 𝑓
𝑠
+ 1 ∗ 𝑁
79. Quiz 2
No. of Trainable parameters (Weights + biases) in a one convolution layer?
No. of filters: 10
Volume of each filter: 3x3x3
Input volume: 32x32x3
80. Quiz 2
No. of Trainable parameters (Weights + biases) in a one convolution layer?
No. of filters: 10
Volume of each filter: 3x3x3
Input volume: 32x32x3
Solution: No need of input volume. It is a catch.
Total trainable parameters = (3x3x3 weight + 1 bias) of each filter x 10 filters
= (27+1) x 10
= (28) x10
= 280.
83. Pooling Layer
Purpose:
1) To reduce the size of the layer to speed up computation.
2) To retain robust features.
Types:
1) Max Pooling
2) Average Pooling
86. Pooling Layer
Salient features:
1) Follows the process of convolution with filters of size 𝑓, stride 𝑠 and padding 𝑝 (not used much)
as the hyperparameters.
2) Filters have no weights. So, no trainable parameters.
3) Pooling operation is carried out channel-wise. Thus, number of channels remain unchanged.
