Monotone Tree-Based GAMI Models by Adapting XGBoost

no code implementations5 Sep 2023 Linwei Hu, Soroush Aramideh, Jie Chen, Vijayan N. Nair

It is straightforward to fit a monotone model to $f(x)$ using the options in XGBoost.

Computing SHAP Efficiently Using Model Structure Information

no code implementations5 Sep 2023 Linwei Hu, Ke Wang

Finally, if even the order of model is unknown, we propose an iterative way to approximate Shapley values.

Interpretable Machine Learning based on Functional ANOVA Framework: Algorithms and Comparisons

no code implementations25 May 2023 Linwei Hu, Vijayan N. Nair, Agus Sudjianto, Aijun Zhang, Jie Chen

To understand and explain the model results, one had to rely on post hoc explainability techniques, which are known to have limitations.

Using Model-Based Trees with Boosting to Fit Low-Order Functional ANOVA Models

no code implementations14 Jul 2022 Linwei Hu, Jie Chen, Vijayan N. Nair

We propose a new algorithm, called GAMI-Tree, that is similar to EBM, but has a number of features that lead to better performance.

Shapley Computations Using Surrogate Model-Based Trees

no code implementations11 Jul 2022 Zhipu Zhou, Jie Chen, Linwei Hu

Shapley-related techniques have gained attention as both global and local interpretation tools because of their desirable properties.

Performance and Interpretability Comparisons of Supervised Machine Learning Algorithms: An Empirical Study

no code implementations27 Apr 2022 Alice J. Liu, Arpita Mukherjee, Linwei Hu, Jie Chen, Vijayan N. Nair

Overall, XGB and FFNNs were competitive, with FFNNs showing better performance in smooth models and tree-based boosting algorithms performing better in non-smooth models.
