question about feature importance

Open fly12357 opened this issue 5 years ago • 0 comments

I train a FM model on my own data, and the final test auc is 71.4%. Then, I use the linear weight dumps from the trained FM model to check the importance of my handcraft feature. But, I found that some feature about the items id which are not very "hot" on online statistic show very big weight. Can you give me some advice about this problem?
