What is Gradient Descent in machine learning?

The process of repeatedly nudging an input of a function by some multiple of the negative gradient is called gradient descent. It’s a way to converge towards some local minimum of a cost function basically valley in a graph.¬† According to Wikipedia, Gradient descent is a first-order iterative optimization algorithm for finding the minimum of a function. To find a local minimum or minimum cost of a function using gradient descent, one takes steps proportional…
