Prediction explanation's Impact numer

Hello,

 

Is it possible to know prediction explanation menu's specific impact numer?

What I can only see is '+++' or '---'.

I know the impact figure is decided by SHAP or XEMP.

How to calculate the impact and can I see the specific results number like 3.45 even by using API?

 

Thank you.

While it doesn't show in the GUI, if you deploy the model and make prediction in the Deployment Environment (MLOps) then the strength of the prediction will be included in the prediction explanation.   Another way is throught Python API
Here is an example of prediction explanation with strength included.  The result was obtained through calling the deployed model in MLOps

Thank you for specific answer!

Where can I see the strength in MLOps GUI?
