Information Theory: I forget which publishing house it was. It is a very thin book and it is very good. There is a good talk about the measurement of information, the understanding of entropy and the Markov process (there is no such thing in the company now, I'll go back and find it and make it up).

Specifically, the problem is split first, and then a classifier is trained for each split second classification task. During the test, the prediction results of these classifiers are integrated to obtain the final multi-classification results. The key here is how to split multiple classification tasks and how to integrate multiple classifiers.Grandma Lily woke up from her dream and hurriedly went to see Little Charlie nearby. At this time, Little Charlie, her small mouth still sucking and sleeping soundly. It turned out to be a dream. Grandma Lily only recovered for half a day and took a long breath.
