How to find Feature importance scores (Growth Hack) - Medium
WebNov 9, 2024 · Formally, the importance of feature j is given by. To summarize, a feature’s importance is the difference between the baseline score s and the average score obtained by permuting the corresponding column of the test set. If the difference is small, then the model is insensitive to permutations of the feature, so its importance is low. Web1.13. Feature selection¶.
