Machine learning terms explained: Gradient optimization and stochastic functions

This article delves into complex machine learning terminology, focusing on gradient-based optimization and stochastic objective functions. It explains first-order gradient-based optimization as a method using only the first derivative to minimize loss functions, illustrating the process with mathematical examples. The piece also defines stochastic objective functions as those involving randomness, often approximated by using small batches of data instead of the entire dataset to calculate gradients, which introduces noise but is computationally efficient.
