Automatically predict trends and behaviors.
Data mining automatically queries the prediction information in a large database. A long time ago, a lot of manual analysis of problems could quickly and directly draw conclusions from the data itself.
Associative analysis
Data association is an important knowledge that can be found in data. If there is a certain law between two or more variables, it is called correlation. Correlation can be divided into simple correlation, time correlation and causal correlation. The main purpose of Jiayin IT training discovery association analysis is to find out the hidden network in the database.
strand
The records in the database can be divided into a series of meaningful subsets, namely clustering. Clustering can improve people's understanding of objective reality and is the premise of concept description and deviation analysis. Jiayin IT training discovery clustering mainly includes traditional pattern recognition methods and mathematical classification.
Conceptual description
Concept description is a description of the content of the target category and a summary of the related characteristics of the category. Concept description is divided into feature description and difference description, which describe the differences between different objects. Jiayin computer training believes that a feature description will only affect the same elements of all objects.
