Venn diagrams representing the relationships among feature sets and subsets, and their model outcomes by cross validation within dataset2431. The black large circles representing the space of all 1566 possible features, formally this is set Sall 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, S2431-A and S2431-B are the grey circles and they represent the average of pair wise comparisons of feature subsets found by cross validation on dataset2431 where S2431-A⊂Sall and S2431-B⊂ Sall and the average sub set cardinality is represented by the diameter of the grey circle and the S2431-A ∩ S2431-B is provided as the average fraction of features shared between sub sets.
