commonly said bitmap in the computer. In the process of transforming images from physical images to digital images, the most critical place is sampling and quantification, which may be familiar to both of us, but we still need to understand and think deeply.If said, in the process of scanning, we will scan the resolution of a large, that is, the sampling rate setting is large, the scanned digital image resolution is also larger, that is, the width and height of the image is larger, conversely,

. Naive Bayesian classifier has two kinds of polynomial model (word bag) and Bernoulli model (Word set) for text classification.2, Naive Bayes basic knowledgeFor the random test e There are two random events, A, B, and the probability of a occurring in the condition that the B event occurs is:where P (AB) is a joint probability of a A, B two event. The upper formula can be deformed by using the multiplication equation:So we get the Bayesian formula. Bayesian text classification is based on this

This article is intended to help you understand the dots behind the TCP cubic congestion control algorithm and why its equations are that way. All along, many people feel that the cubic algorithm is very complex, involving complex heavenly book-like "3 times Curve" ... However, Cubic is not as complex as everyone thinks, and it is complicated because it does not understand its history and background.This article is to introduce the history and background of cubic ...
