Permutation test sklearn
WebCompute permutation importance - part 1 ¶ Since auto-sklearn implements the scikit-learn interface, it can be used with the scikit-learn’s inspection module. So, now we first look at the permutation importance, which defines the decrease in a model score when a given feature is randomly permuted. WebThe first two permutation types are for paired sample statistics, in which all samples contain the same number of observations and observations with corresponding indices along axis …
