## Description

This project is an educational codebase and reference library that translates theoretical deep learning concepts into executable PyTorch code. It serves as a practical implementation of a deep learning textbook, providing a course-like structure of guided exercises and architectural examples for learning purposes.

The repository includes a library of standard neural network architectures, including linear, convolutional, recurrent, and transformer models. It specifically implements a variety of deep learning patterns such as multilayer perceptrons, VGG networks, gated recurrent units, and long short-term memory networks.

The codebase covers broad capability areas including computer vision for image classification and object detection, as well as natural language processing for sequence modeling and translation. It also implements fundamental machine learning components such as linear and softmax regression, probabilistic classification, and a suite of gradient-based optimization algorithms.

The project is primarily delivered as a collection of Jupyter Notebooks.
