NB and shapash problem

[npapan69]

Dear All,

I have an error message when trying to compile xpl if I use a naive bayes model

model not supported by shapash, please compute contributions by yourself before using shapash

Any help with this will be appreciated

many thanks in advance

Hi,

We don't compute contributions with naive bayes model, but you can compute your own contributions (with shap.KernelExplainer for example).
Then you can compute Shapash with your contributions.
You can see this tutorial : https://github.com/MAIF/shapash/blob/master/tutorial/explainer/tuto-expl01-Shapash-Viz-using-Shap-contributions.ipynb

Dear Thomas,
Many thanks for your response. Is it possible to define a probability threshold other than 0.5 on the predictor?
