This is especially … WebThe permutation feature importance is defined to be the decrease in a model score when a single feature value is randomly shuffled. For instance, if the feature is crucial for the model, the outcome would also be permuted (just as the feature), thus the score would be close to zero. Afterward, the feature importance is the decrease in score.

WebDefinition: A permutation τ of n elements is a bijective function having the set { 1, 2,..., n } both as its domain and codomain. The number of permutations of n elements, and hence the cardinality of the set S n is n! So for example, for every integer i ∈ { 1, 2,..., n } there exists exactly one integer j ∈ { 1, 2,..., n } for which τ ( j) = i.
