A Gentle Introduction to Learning Rate SchedulersImage by Author | ChatGPT Ever wondered why your neural network seems to get stuck during training, or why it starts strong but fails to reach its full potential? The culprit might be your learning rate – arguably one of the most important hyperparameters in machine learning. While a fixed learning rate can work, it often leads to suboptimal results.

Learning rate schedulers offer a more dynamic approach by automatically adjusting the learning rate during training. In this article, you’ll discover five popular learning rate schedulers through clear visualizations and hands-on examples. You’ll learn when to use each scheduler, see their behavior patterns, and understand how they can improve your model’s performance. We’ll start with the basics, explore sklearn’s approach versus deep learning requirements, then move to practical implementation using the MNIST dataset. By the end, you’ll have both the theoretical understanding and practical code to start using learning rate schedulers in your own projects. Imagine you’re hiking down a mountain in thick fog, trying to reach the valley.

The learning rate is like your step size – take steps too large, and you might overshoot the valley or bounce between mountainsides. Take steps too small, and you’ll move painfully slowly, possibly getting stuck on a ledge before reaching the bottom. You can run the code for this section in this jupyter notebook link.

We saw in previous lectures that the Gradient Descent algorithm updates the parameters, or weights, in the form: Recall that the learning rate \(\alpha\) is the hyperparameter defining the step size on the parameters at each update. The learning rate \(\alpha\) is kept constant through the whole process of Gradient Descent.

But we saw that the model’s performance could be drastrically affected by the learning rate value; if too small the descent would take ages to converge, too big it could explode and not converge... How to properly choose this crucial hyperparameter? In the florishing epoch (pun intended) of deep learning, new optimization techniques have emerged. The two most influencial families are Learning Rate Schedulers and Adaptative Learning Rates. This notebook improves upon the SGD from Scratch notebook by: Using efficient PyTorch DataLoader() iterable to batch data for SGD
