Videos CourseMany people start to learn from the machine through video resources. I saw a lot of video resources related to machine learning on YouTube and Videolectures. The problem with this is that you may just watch the video and not actually do it. My suggestion is that when you watch the video, you should take more notes, and then you will discard your not

Once you have mastered the basics of mathematics, your understanding of these models can easily transcend the formula itself.The difference between deep knowledge and shallow knowledgeBean leaves think that when we learn knowledge, we should learn to differentiate, what is deep knowledge (knowledge), what is shallow knowledge (shallow knowledge).Some knowledge is shallow knowledge, only need to remember to know. But

(It's worth noting that each user is required to build his own regression model.)From another point of view, it is also possible to give each user the degree of preference for a particular film (i.e. weight), then learn the characteristics of each film, and finally use the regression to predict those who have not been rated film.Of course, it is also possible to optimize the level of each user's passion for different types of movies and the characteristics of each film.

Online learning is different, it updates the model parameters for each new example,

It is obviously not enough to know the specific process of these methods. The key is to learn how to use them. The so-called best way to master knowledge

Therefore, this solution is not the smallest solution that is solved step by step, as mentioned earlier by the PLA algorithm.Answer is the reason for more emphasis on the results, the direct solution is the mathematical derivation of the exact solution, so that the minimum solution is obtained, in line with the solution conditions, but also to solve the pseudo-inverse algorithm (this method is called Gaussian elimination method, see also Gauss, looked at
