Derivatives and Their Applications

Calculus serves as an indispensable tool in the machine learning domain, and comprehending derivatives is crucial for understanding how models learn and adapt. This chapter delves into the concept of derivatives, exploring their fundamental role in analyzing and optimizing functions that underpin machine learning algorithms.

You will start with the basics of differentiation, learning how to compute derivatives of common functions and interpret their meanings. We'll then progress to more intricate applications such as the chain rule, which enables the differentiation of composite functions, essential for backpropagation in neural networks. Additionally, you'll learn about partial derivatives, a key component in understanding how changes in multiple input variables influence a function's output, particularly relevant in multivariable calculus.

Moreover, this chapter examines how derivatives facilitate optimization techniques like gradient descent, a cornerstone in training machine learning models. By the end, you'll possess the mathematical tools to not only compute derivatives but also apply them effectively in creating models that learn from data.
