[source code co reading] detailed explanation of bisect module of built-in bisection algorithm (half algorithm) in Python

1. Introduction Bisection algorithm is a very common and commonly used algorithm in programming. Even so, I didn't expect that Python official has a special module to realize most operations of the algorithm. The module is bisect. In fact, the functions provided by this module are mainly used in such a scenario, that is, after each us ...

Pytoch learning notes -- transforms

Why transforms? Generally, the collected image samples are different in size and brightness. In deep learning, we want the sample distribution to be independent and identically distributed, so we need to normalize the samples.Sometimes only a small amount of sample data can be obtained, and it is not easy to obtain a large number of samples. H ...
