Gradient Descent
About Gradient Descent
Gradient descent is a fundamental optimization algorithm used to minimize functions by iteratively moving toward minimum values in parameter space. It is central to training most machine learning models, including neural networks, and has evolved into numerous variants and optimizations to handle large scale data, non convex landscapes, and high dimensional spaces.
