Similar to finding the line of best fit in linear regression, the goal of gradient descent is to minimize the cost function, or the error between predicted and actual y. In order to do this, it requires two data points—a direction and a learning rate. These factors determine the partial ...
Gradient descent is a versatile and powerful optimization technique that is central to many machine learning algorithms. Its iterative approach to minimizing cost functions makes it an essential tool for training models, from simple linear regressions to
Types of Gradient Descent Algorithms In this article, I am going to discuss Gradient Descent in detail, explaining the different algorithms for optimisation apart from the standard gradient descent algorithm. To discuss the various gradient descent algorithms, I am going to use the Logistic Regression...
