Feature selection test

For the forward selection test:
Assuming A,B,C,D,E;
do we have to first check the performance of the model taking every feature singularly and then move forward with our testing process?

sir please help me with my doubt,

hey @prerit_goyal ,
for forward selection test ,
you can assume that way. But actually you need to make there pairs in that ,
for example A , B and B,A won’t have much difference in model performance.
hence after selecting one feature , then check for all the pairs possible and choose wisely.
