Review reminder sent to @janeadams |
A succinct and interesting read on evaluating permutation feature importance (PFI) impacts on three different classification models (Random Forest, LightGBM, and SVM) with varying proportions of subsampled data featuring unbalanced classes. I have minor comments but overall I think this a great contribution.
I particularly appreciated the pre-filtering step of using hierarchical clustering of features to account for potential collinearities. I also appreciated that the authors used multiple data sets and evaluated at a range of sample proportions. This is a nice example of how a lot of scientific computing python libraries can come together into a single interesting experiment. |
Thank you for the encouraging comments and observations on the paper @janeadams . We are currentlly addressing some of the comments raised by @apaleyes . Hopefully, all observations raised will be responded to early next week and the paper updated accordingly. |
