Optimizing Neural Networks: Adjusting the Learning Rate in Python

Finding the right learning rate is often the difference between a neural network that converges perfectly and one that fails to learn at all. This text-based course guides you through the mechanics of optimization, helping you transform slow or unstable training runs into efficient, high-performing models. In this course, you will learn to: • Understand the core role of the learning rate in gradient descent. • Analyze training curves to diagnose underfitting and unstable convergence. • Apply learning rate decay and modern scheduling techniques to improve training efficiency. • Implement learning rate tuning using Python with popular machine learning frameworks. • Compare different optimizers and how they interact with learning rate settings. • Practice tuning model performance on classic classification tasks like the MNIST dataset. We begin with foundational concepts of loss landscapes and gradient descent before diving into practical code implementations. This course is designed for beginner Python developers and aspiring data scientists ready to move beyond default model settings, with no advanced math prerequisites.
