To verify efficiency of the new featureselectionapproach and improved TF-IDF formula, a multi-set of experiments base on the Chinese text categorization test system platform have been taken.
Different features have different contribution to saliency, so a new approach for salient region detection with automatic featureselection and weighting is proposed.
Taking community structure as measurement index for featureselection, a new featureselection measure approach based on modularity coefficient community structure is proposed.
