Neural Network Weight Updates and Gradient Descent in Python

Have you ever wondered how neural networks actually learn from data and improve their predictions? Understanding the mechanics of weight updates and gradient descent is the key to demystifying deep learning and building models that perform. This text-based course guides you through the core mathematical concepts and practical Python implementations of neural network training. You will start with foundational definitions of loss functions and gradients, then move step-by-step from manual weight calculations to modern optimization algorithms used in industry today. What you'll learn: - Understand the core mathematical principles behind gradient descent and backpropagation. - Calculate weight updates manually to build a deep intuitive grasp of network optimization. - Implement gradient descent algorithms from scratch using clean, modern Python with type hints. - Explore modern optimization techniques including Momentum, RMSprop, and Adam. - Apply automatic differentiation concepts to streamline training workflows. - Troubleshoot common training issues like vanishing and exploding gradients. You will begin by learning essential terminology and the mathematical foundations of loss landscapes. From there, you will read through clear, step-by-step written explanations and analyze Python code snippets that demonstrate how weights adjust during training. This course is designed for beginners, software developers, and aspiring data scientists who want a clear, conceptual, and practical understanding of neural network training without complex prerequisites.
