probability of an object (that is, the probability that the object belongs to a certain class), and then select the class with the maximum posteriori probability as the class to which the object belongs. At present, there are four kinds of Bayesian classifiers: Naive Bayesian classification, TAN (tree Augmented Bayes Network) algorithm, BAN (BN augmented Naive Bayes) Classification and GBN (general Bayesian Network). This paper focuses on the princip

I usually only use Python, and it is very convenient to do some simple mathematical computing without pursuing speed, but I must learn C ++ at work. I usually only use Python, and it is very convenient to do some simple mathematical computing without pursuing speed, but I must learn C ++ at work. Reply: I also learned Python first and then C ++.

Hashlib ModuleThe hashlib in Python provides us with a common digest algorithm, such as MD5, SHA1So now the question is, what is the abstract algorithm ? Abstract the algorithm is also called hash algorithm and hashing algorithm.It refers to the arbitrary length of data, thr

Python uses the backtracking algorithm subset tree template to solve the problem of finding zero. python returns zero. The example in this article describes how Python solves the problem of finding zero Based on the subset tree template of the Backtracking Method. We will sh

also according to the model, judging someone belongs to a disease or a certain situation of the probability of how much, that is to see how much this person is likely to belong to a disease.Logistic regression is mainly used in epidemiology, and the common situation is to explore the risk factors of a disease, predict the probability of occurrence of a disease according to the risk factors, and so on. For example, to explore the risk factors of gastr

hash value is found in the database.Select a hashing algorithm The cryptographic hash algorithm is a common hashing algorithm. Similar to md5,sha1,sha256 this can be found in any language can be called a standard library, they are very effective for simple use cases. For example, to import a hashlib module in

Python development [Chapter 28]: algorithm (II), chapter 28 of pythonHeap sorting 1.-tree and Binary Tree Introduction A tree is a data structure, such as a directory structure. A tree is a data structure that can be recursively defined. A tree is a collection of n nodes: If n = 0, this is an empty tree; If n> 0, there is one node as the root node of the tree. Other nodes can be divided into m sets, and

This article mainly introduces the Kmeans and kmeans ++ algorithms, explains the shortcomings of the Kmeans algorithm and the implementation ideas of the kmeans ++ algorithm, as well as the Kmeans ++ algorithms implemented in Python and matlab, for more information, see 1. start with Kmeans Kmeans is a very basic clustering
