Abstract

The invention is suitable for the field of computers, and provides a supporting point set selection method, comprising receiving data sets and number of supporting points, determining a candidate set and an evaluation set from the data sets, obtaining a plurality of supporting point sets according to the candidate set and the number of the supporting points, grouping data in the evaluation set two by two to obtain data pairs, establishing an evaluation data pair set by using the grouped data pairs, judging whether each supporting point set can exclude each data pair in the evaluation data pair set according to preset exclusive rules, and obtaining excluded number of each supporting point set, selecting the maximum value in the excluded number, and using the supporting point set corresponding to the maximum value as a selected supporting point set. Under the condition of determining the candidate set and the evaluation set, the embodiment of the invention can select out the supporting point set with the optimal performance by only one time, and the problem in the prior art that combination of two supporting points, sequentially selected out by the optimal objective function value in the Incremental algorithm may not be the optimal supporting point combination is avoided.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a method and device for selecting a set of support points. Background technique [0002] There are relatively few explorations on Variety (type) in the 4V characteristics of big data. The diversity of data generally refers to the wide range of types (text, image, audio, video, spatial data, time-space series, etc.) and sources (media, education, economy, medical care, aerospace, etc.). There are generally two ways to deal with a wide variety of data: a dedicated system or a general system. The dedicated system tailors a special processing system for each data type, so it is necessary to develop multiple processing systems, which have better performance but high development and maintenance costs and narrow scope of application. A general-purpose system develops a unified system to process data of various data types, and its performance may be poorer than that of a special-pu...
