Regarding variable selection for algorithms



Hello Friends,
I wanted to know is there one method of variable selection for algorithms like linear, logistic regression , random forest , support vector machine…or different methods of variable selection depending on the algorithm…

Hi @amodaks,

The variable selection is not dependent on the algorithm. You can refer the following article :


Variable Selection Algorithms :

  1. Filter Methods( Chi squared test, information gain and correlation coefficient scores).
  2. Wrapper Methods.
  3. Embedded methods (regularization methods).


Each method has some situations you used for.
