How to speed up the algorithm?

[kkckk1110]

I found the process extremely slow when having many features. How can I speed up the process? Can I use the GPU to accelerate?

GPU is not supported. Ensure to use all CPU cores in your estimator, if not done already. Maybe consider using a faster/simpler estimator. If the dataset is too huge, use subsampling to speedup. The feature importance should not change extremely when 10k rows compared with 10m rows. When all of the above fails, try to filter out some features with simpler methods and run boruta afterward. Hope this helps.

I think these are great key points that should be included in the main documentation.
