Interpret ML.NET models with Permutation Feature Importance
WebAug 16, 2024 · Feature Selection or attribute selection is a process by which you automatically search for the best subset of attributes in your dataset. The notion of “best” is relative to the problem you are trying to solve, but typically means highest accuracy. A useful way to think about the problem of selecting attributes is a state-space search. WebDec 10, 2024 · In this article. Using Permutation Feature Importance (PFI), learn how to interpret ML.NET machine learning model predictions.
