object importance (LeafInfluence)

[SergeiShirkin]

I know that in CatBoost in Python API there is a possibility to calculate object importance (don't confuse it with feature importance) with get_object_importance method.

I would like to know is there a similar option in LightGMB?

At present, there is no functionality for calculating object importance in LightGBM.

Are you talking about this one method?

According to the documentation, the algorithm behind is described in this paper: https://arxiv.org/pdf/1802.06640.pdf
