 GPX is a Gaussian process regression model that can output the feature contributions to the prediction for each sample, which is implemented based on the following paper:  
 **Yuya Yoshikawa, and Tomoharu Iwata. "[Gaussian Process Regression With Interpretable Sample-Wise Feature Weights.](https://ieeexplore.ieee.org/abstract/document/9646444)" IEEE Transactions on Neural Networks and Learning Systems (2021).**
