Study Notes

Convolutional Neural Networks (CNNs)

CNNs utilize convolution operations rather than matrix multiplication for at least one layer.
The convolutional layer functions as a feature extractor, identifying features such as edges, corners, and endpoints in images.
CNNs progress through layers that learn features, starting with low-level features and evolving into high-level object representations.

Learning Process in CNNs

Early layers focus on simple features (e.g., edges), while deeper layers capture more complex structures (e.g., parts of objects).
The goal is to transform images into a format where classes can be separated by linear classifiers.

Key Conferences in Computer Vision (CV)

Major international conferences include CVPR (Computer Vision and Pattern Recognition), ICCV (International Conference on Computer Vision), and ECCV (European Conference on Computer Vision).
Prominent machine learning conferences with CV research contributions include NeurIPS (Neural Information Processing Systems), ICML (International Conference on Machine Learning), and ICLR (International Conference on Learning Representations).

Evolution of Deep Learning

Deep learning concepts have origins that trace back several decades, leveraging advancements in neural networks.
Visual features are progressively extracted through various layers: shallow layers handle basic visuals while deeper layers account for high-level abstractions.

Vision Transformers (ViT)

Introduced the concept of treating image patches as words, representing the idea of "An image is worth 16x16 words" for efficient image recognition.

Applications of Deep Learning

Deep learning is pervasive in various applications, from image captioning to vision question answering (VQA) and 3D vision understanding.
Neural Radiance Fields (NeRF) are explored for applications in depth estimation and enhanced 3D vision capabilities.

CNN Architecture and Layer Types

CNN architectures are designed to effectively process and analyze grid-like data, such as images. These models typically consist of sequentially stacking layers, including Convolution (CONV) layers that extract features, Pooling (POOL) layers that reduce dimensionality, and Fully Connected (FC) layers that enable classification tasks.
A trend in modern architectures favors deeper networks with smaller filters, moving towards architectures that may exclude pooling and fully connected layers entirely, focusing solely on convolutional layers.

Parameters and Operations in CNNs

The pooling layer reduces spatial dimensions while preserving feature integrity; it is achieved through hyperparameters such as spatial extent (F) and stride (S).
Output dimension calculation from a Conv layer is given by:
- Height (H2) = (H1 - F) / S + 1: In this equation, H1 represents the initial height of an object, F denotes a fixed offset or adjustment value, and S is the scaling factor that translates the dimensions. This calculation determines the new height of the object after accounting for these variables.
- Width (W2) = (W1 - F) / S + 1: Similar to the height calculation, W1 signifies the original width, while F is the same fixed offset. S, again, serves as the scaling factor. This formula applies the same principles to establish the modified width of the object after adjustments.
Fully Connected (FC) layers contain neurons connected to the entire input volume, forming the concluding stage of a CNN architecture.

Summary of Trends in CNN Design

There is an apparent shift towards smaller filter sizes and deeper network structures in recent CNN developments.
Historical architectures in deep learning typically adhered to the structured format of [(CONV-RELU)*N-POOL?]*M-(FC-RELU)*K, SOFTMAX. In this notation, 'CONV' stands for convolutional layers, 'RELU' denotes the rectified linear unit activation function, 'POOL' represents pooling layers, and 'FC' signifies fully connected layers. The parameters N, M, and K are crucial, as they influence the model's complexity, depth, and ultimately its performance on various tasks.

CIFAR-10 Dataset

Contains 10 classes including airplanes, automobiles, birds, cats, and more.
Commonly used for tasks in machine learning such as image classification, object recognition, and transfer learning.
Useful for benchmarking and testing convolutional neural networks (CNNs).

ImageNet

Comprises 14 million images across over 21,000 classes, with about 1 million images featuring bounding box annotations.
Annotations performed by humans via the crowdsourcing platform, Amazon Mechanical Turk.
Hosts the ImageNet Large-Scale Visual Recognition Challenge (ILSVRC), an annual competition promoting advancements in computer vision.
Has significantly contributed to the development and benchmarking of state-of-the-art algorithms in the field.

Classical CNN Models

LeNet

Pioneered by Yann Lecun in 1989 for digit recognition, first to apply backpropagation for visual feature learning.
Architecture includes two convolutional layers and three fully connected layers, with an input size of 32x32.
Utilizes 6 and 12 feature maps and 5x5 filters, with a stride of 2 for dimension reduction.
Incorporates a scaled tanh activation function and uniform random weight initialization.

Role of CNNs in Image Classification

CNNs are optimized for processing grid-like data, particularly images.
Capable of automatically learning pertinent features from raw pixel data, bypassing the need for manual feature engineering.
Utilize convolutional layers for local pattern detection, followed by pooling layers to reduce spatial dimensions, enhancing model robustness and preventing overfitting.
Final classification decision is made through fully connected layers based on extracted features.

Data Handling in CNNs

Data augmentation strategies vary and should ideally involve insights from domain experts to ensure relevance.
It's important to employ multiple metrics to report results, as they often offer complementary insights.
Present both qualitative and quantitative results to provide a comprehensive evaluation of model performance.
