Permutation Feature Importance
Permutation feature importance is a method for evaluating the importance of each feature in a machine learning model. It works by shuffling the values of each feature, one at a time, and then measuring the impact on the model’s performance. The idea is that if shuffling a feature significantly decreases the model’s performance, then that feature is likely to be important. This method can be used to identify the most important features in a model, which can be useful for feature selection and dimensionality reduction. It can also be used to identify features that are redundant or not useful, and can be removed from the model.
