Result of each iteration during the iterative feature elimination process when applied to two datasets (Breast and AML) for 3 different runs of RGIFE. Green and blue equal or better performance than the reference iteration. Green is used when the removed attributes were the bottom ranked, otherwise blue is employed. Red represents worse performance, yellow shows the identification of a soft-fail. The last non-grey square indicates the last iteration of the RGIFE run
