Abstract:
Feature Selection is one of the focuses in pattern recognition field. To select the most obvious features, there are some feature selection methods such as LASSO, Bridge Regression and so on. But all of them are limited in select feature. In this paper, a summary is listed. And also the advantages and limitations of every method are listed.
