Venn diagrams representing the relationships among feature sets and subsets, and their model outcomes by cross validation within dataset ₂₄₃₁ . The black large circles representing the space of all 1566 possible features, formally this is set S _all with cardinality of 1566. The smaller grey circles represent the feature subsets found by CFS selection and the intersections of the grey circles represent the features that were on average consistently found between pair wise comparisons among the cross validations. Specifically, S _2431-A and S _2431-B are the grey circles and they represent the average of pair wise comparisons of feature subsets found by cross validation on dataset₂₄₃₁ where S _{2431-A ⊂}S _all and S _2431-B ⊂ S _all and the average sub set cardinality is represented by the diameter of the grey circle and the S _2431-A ∩ S _2431-B is provided as the average fraction of features shared between sub sets.
