WebPermutation can be classified in three different categories: Permutation of n different objects (when repetition is not allowed) Repetition, where repetition is allowed Permutation when the objects are not distinct (Permutation of multi sets) Permutation and combination are the ways to represent a group of objects by … WebThe permutation feature importance depends on shuffling the feature, which adds randomness to the measurement. When the permutation is repeated, the results might vary greatly . Repeating the permutation and averaging the importance measures over repetitions stabilizes the measure, but increases the time of computation.
