Explain how the gradient descent algorithm works.

解释：

The gradient descent algorithm is designed to minimize a function of several variables. It chooses starting values for the variables. It then chooses the direction of steepest descent (i.e., the direction in which the variables should be changed to produce the best improvement in the objective function and takes a step in that direction. It then recalculates the direction of steepest decent, takes another step, and so on.
