Implementation of gradient descent algorithm for machine learning
According to Wu Enda's machine learning video, the gradient descent algorithm is learned and implemented by code.
The purpose of gradient descent algorithm is to find the value of theta, which minimizes the cost function, and to attach relevant formulas.
The above figure is the definition of hypothetical function and cost f ...
