Neural Networks and PyTorch: Guided Theory and Practice Exercises

Building a strong foundation in deep learning requires both understanding the core mathematics and knowing how to implement them in code. This text-based guide helps you bridge the gap between neural network theory and practical PyTorch development. By working through clear explanations and structured self-assessment questions, you will solidify your comprehension of how deep learning models learn. You will transition from a theoretical understanding of backpropagation to writing clean, modern PyTorch code for real-world classifiers. What you'll learn: Understand the core architecture of neural networks, including layers, activation functions, and weights; Trace the mathematical flow of forward propagation and backpropagation step-by-step; Implement binary and multi-class classifiers using standard PyTorch modules; Configure modern optimizers and loss functions to train models efficiently; Practice debugging common PyTorch tensor shape mismatches and runtime errors; Apply best practices for data loading and model evaluation using modern PyTorch APIs. The course begins with essential deep learning terminology and foundational mathematical concepts before moving into hands-on PyTorch implementation and structured self-test scenarios. This course is designed for beginner developers, data science enthusiasts, and students who want to test and reinforce their understanding of deep learning basics without needing prior PyTorch experience.
