How to fully show and validate the "show_prediction" results?

284 Views Asked by At

I'm trying to use eli5.show_prediction to explain feature importance at the record level. Below is part of the results I'm getting.

The raw score value shown below is -0.329, which corresponds to probability value exp(-0.329)/(exp(-0.329) + 1) = 0.418484. However, the probability I calculated for this record using my XGB model turns out to be 0.8953. Is this difference expected? I used weights when building my XGB model, I wonder whether that's the issue.

Additionally, I used 100~ish features in my XGB model, but the eli5.show_prediction only shows feature importance of the top 70. What should I do in order to make the program output feature importance for all ~100 features?

Below is the output given by .show_prediction currently:

_y (score -0.329) top features       
Contribution    Feature Value

0.126   feature 1   1844

0.126   feature 3   100

0.108   feature 10  47

0.086   feature 100 100

0.057   feature 20  0

0.043   feature 5   47

0.039   bias    1

0.038   feature 56  0
