任永功 %A 林楠 %J 计算机科学 %D 2009 %I %X In the process of the text feature selection,the space dimension of the original characteristics is too high,excessive calculation,and there is greater irrelevance and redundancy features,a feature selection algorithm based on dynamic programming(DPFS) was proposed.First,selecting the feature from the original feature set based on dynamic programming and the analysis of features' relevance and classes' relevance,reserve features that are the strong correlation and the weak correlation;and then,for the featu... %K Features selection %K Correlation %K Redundancy %K Dynamic programming
