Survey of semi-supervised feature selection methods

How to select features on semi-supervised data sets by incomplete supervisory information has become a research hotspot in the field of pattern recognition and machine learning.In order to facilitate researchers to systematically understand the research status and development trend of semi-supervised feature selection,this paper reviewed the semi-supervised feature selection methods.This paper first discussed the classification of semi-supervised feature selection methods and divided them into graph-based methods,pseudo-label-based methods,SVM-based methods and other methods according to their theoretical basis,then introduced and compared typical methods for each category,and then sorted out hot applications of semi-supervised feature selection.Finally,this paper looked forward to the future research directions of semi-supervised feature selection.
