-Newton method, and compared with the gradient descent algorithm, the advantages of these algorithms are:
First, there is no need for manual selection of step size; second, it is usually faster than gradient descent algorithm;
But the downside is more complicated.
multi-Class classification problem
For multiple classification problems, it can be seen into two categories of classification problems: keep One of them, the rest as the other class.
For each Class I trains a classifier of a logistic
