Embodiment 1

[0028] The embodiments described by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0029] A data mining automatic feedback system involved in this embodiment, its work flow chart is as follows figure 1 As shown, the specific steps are as follows:

[0030] Step 1. Data segmentation

[0031] Such as figure 2 As shown, the source data to be mined is randomly divided into training data and test data in proportion, in which the training data will be used to train the data mining algorithm model, and the test data will be used to evaluate the accuracy of the data mining model. Sub-segmentation and different random prototypes are used to avoid the random impact of random segmentation on the evaluation of algorithm results.

[0032] Step 2. Train and evaluate data mining algorithms

[0033] Such as image 3 As shown, if the output of the data mining algorithm is a model, the indepe...

Abstract

The invention provides a method for establishing a data mining automatic feedback system, used for solving the problem that manual feedback is continuously needed to implement adjustment and optimization during an existing data mining implementation process. The data mining automatic feedback system established according to the method comprises a data segmentation module, a result assessment module and a parameter adjustment module, wherein the three modules work cooperatively to form feedback, and automatically adjust and optimize a parameter of a data mining algorithm, so that more labor cost is saved than traditional data mining. The algorithm parameter is effectively, accurately and automatically adjusted by an automatic parameter adjustment algorithm, parameter adjusting efficiency is effectively improved, and actual waste caused by excessively traversing a parameter value range during an automatic process is reduced.

Description

technical field [0001] The invention relates to the field of data mining, in particular to a method for establishing an automatic feedback system for data mining. Background technique [0002] With the rapid development of big data technology, data mining technology is more widely used. Universities, research institutes, governments and technology companies are widely using data mining technology. [0003] A complete data mining process often includes: data preprocessing, data mining algorithm execution, and data result reporting. The most critical step is to obtain the results of data mining through the execution of data mining algorithms. This step often requires a lot of manual intervention and feedback. Manual intervention and feedback are manifested as observing the results of the algorithm execution through the expert's empirical model, and then readjusting the algorithm parameters according to the results to re-execute the algorithm to obtain new results until the da...
