[basic knowledge of deep learning - 48] characteristics of Bayesian network

Characteristics of Bayesian Networks

• Bayesian network mainly introduces two basic concepts ： Directed acyclic graph and conditional probability set .
• The nodes of a directed acyclic graph are features and categories , Edge is the relationship between two features or features and categories , Not independent of each other .
• The main concept of conditional probability set is conditional independence , That is, a node is given its parent node , It is independent of other nodes .
• Bayesian networks are not concerned with causality , It's the dependency between variables .
