Algorithm 1
Description of the MLFSSM algorithm.
| Algorithm: MLFSSM | | Input: | | dataset X; | | input feature set F; | | Begin | | For l = 1, …, L | | Calculate for f ∈ F using equation (1); | | Calculate posl,f for f ∈ F using equation (3); | | Generate M · l-layer’s feature subsets by pos values; | | For m = 1, …, M | | Construct classification models using ; | | Endfor; | | If the accuracy rate of top T · l-layer’s feature subsets reaches 100% | | Break; | | Endfor; | | Return the topmost subset of l-layer; | | End |
