Embodiment 1

[0040] A. Data separation

[0041] Extract several sampled data from the data source, calculate the distribution relationship of the sampled data, and separate the remaining data in the data source according to the distribution relationship of the sampled data to form several data sets. The characteristic elements contained in each sampled data are: The eigenvector of its corresponding data set;

[0042] B. Data screening

[0043] Determine the weight value of each element in the feature vector according to the selected filter conditions, filter the data set in order of weight value from high to low, and modify the elements of the feature vector and their weight values ​​according to the filtering results;

[0044] C. Data iterative processing

[0045] Such as figure 2 In the iterative processing steps shown, the iterative matrix is ​​set according to the format of the target set, the data set is multiplied by the iterative matrix, and then multiplied by the corrected eige...

Embodiment 2

[0061] A. Data separation

[0062] Extract several sampled data from the data source, calculate the distribution relationship of the sampled data, and separate the remaining data in the data source according to the distribution relationship of the sampled data to form several data sets, and reserve between two adjacent data sets There is an overlapping area of ​​10% to 15%, and the feature elements contained in each sampled data are the feature vectors of the corresponding data set;

[0063] B. Data screening

[0064] Determine the weight value L of each element in the feature vector according to the selected filter conditions, filter the data set in sequence according to the order of the weight value from high to low, and modify the elements of the feature vector and their weight values ​​according to the filtering results; Correction The formula is as follows:

Description

technical field [0001] The invention belongs to the technical field of data mining, and relates to a data mining method and a data mining system. Background technique [0002] Data mining (Data Mining, DM) is a hot issue in the field of artificial intelligence and database research. The so-called data mining refers to the non-trivial process of revealing hidden, previously unknown and potentially valuable information from a large amount of data in the database. . Data mining is a decision support process, which is mainly based on artificial intelligence, machine learning, pattern recognition, statistics, database, visualization technology, etc., to analyze enterprise data highly automatically, make inductive reasoning, and dig out potential The model helps decision makers adjust market strategies, reduce risks, and make correct decisions. Existing data mining methods generally have a large amount of calculation, and the problem of slow response often occurs when facing a d...
