나는 이제까지 특성을 선택할때 correlation matrix를 사용했는데 이게 처음 사용할때는 특성고르기 엄청 편하고 좋다 생각했었다.
하지만 순열 중요도를 배워버렸다는거..물론 주의해야하는 부분들이 있지만 매우 직관적이고 주의해야하는 부분도 조금만 꼼꼼히 확인한다면 큰 문제없는 아주 좋고 편한 기능이다. 어떤 특성을 사용해서 모델을 만들지 모르는 사…

### Summary
Our implementation of `HistGradientBoosting` does not shuffle the feature at each node to find the best split. Note that our `GradientBoosting`, `RandomForest`, and `DecisionTree` use a…

I am using a dataset to compute feature importance using permutation. Have checked results with R implementation, I am getting non zero var importance. What could be the reason? Here is my code

This issue is a follow-up of the PR #20058
## Background
We are aware that our current implementation of mean decrease in impurity is biased:
- it uses statistic from the training set (issue …

## Describe the workflow you want to enable
We have datasets with very large numbers of features, where we only care about feature importance for a subset of them. This can happen when;
- The mod…
