Input: F(c) ∈ ℝN for all objects c ∈ C, n

Output: ${\mathbf{X}}_m(c)\in {ℝ}_m^n$, m ∈ {1, …, M}

Data Structures: Feature subsets ℱm, total number of subsets M, number of features in each subset V

begin

0. for m = 1 to M do

1.    Select V < N features from ℝN, forming subset ℱm;

2.    Calculate ${\mathbf{X}}_m(c)\in {ℝ}_m^n$, for all c ∈ C via GE of the feature space associated with each ℱm;

3. endfor
