The gradient descent method is an optimization algorithm, also known as steepest descent. The steepest descent method is one of the methods for solving unconstrained optimization problems is the most simple and most ancient, although it is not practical, but many effective algorithms are based on it were improved and revised by. The steepest descent method uses the negative gradient direction as the search direction, and the steepest descent method is closer to the target value, and the smaller the step length, the slower the advance.
