Application of a New Feature Generation Algorithm in Intrusion Detection System

Algorithm 2 mgfg method for discrete feature columns.

(i)	Input://Discrete feature columns
(ii)	m: the number of discrete feature columns
(iii)	Catboost_encoders: Converts the discrete attributes of the Q class to continuous feature
(iv)	for i = 1 to m do
(v)	fi_col = Catboost_encoders(fi)
(vi)	F.append (fi_col)
(vii)	end
(viii)	Output: //Feature columns with different granularity.
