Researchers have introduced ParamBoost, a new type of Generalized Additive Model (GAM) that enhances interpretability while allowing for the integration of expert knowledge. This novel approach uses gradient boosting to learn shape functions, fitting cubic polynomials at leaf nodes and incorporating constraints like continuity and monotonicity. Empirical results indicate that ParamBoost outperforms existing state-of-the-art GAMs on various real-world datasets, with the flexibility to selectively apply constraints for tailored applications.
