Algorithm 1 Random Subspace learning classifier.

1:
for $b = 1$ to Bdo ▹ Training phase
2:
Set the dimension $S \leq F$ ;
3:
Select randomly s features from $T_{N}^{F}$ to derive $T_{N}^{S}$ ;
4:
$C L_{b} = B u i l d_R S L (T_{N}^{S}, M L)$ ▹ Build Random subspace learning classifier based on dataset $T_{N}^{S}$ and machine learning algorithm $M L$ ;
5:
end for
6:
for $b = 1$ to Bdo ▹ Testing phase
7:
$P_{b}^{M} ⟵ C L_{b} (Z_{M}^{S})$ ▹ Classify $Z_{M}^{S}$ instances using the built model;
8:
end for
9:
$P_{l}^{M} = M a j o r i t y V o t e ({P_{b}^{M}}_{b = 1}^{B})$ ▹ Find predicted class labels $Y^{M}$ using Majority voting of base classifier models;
10:
return $P_{l}^{M}$ ;
