-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

://developers.google.com/edu/python/?hl=zh-CNcsw=1 This is a two-day short-term training course (two full days, of course), probably seven videos, each of which is followed by a programming assignment that can be completed within one hours of each job. This is my second class to learn Python (the first one is Codecademy python, very early to see, a lot of content are not remembered), then watch video + programming One hours a day, six days to finish, the effect is good, with Python write basic p
