PiML (or ฯ-ML, /หpaษชยทหemยทหel/) is a new Python toolbox for interpretable machine learning model development and validation. Through low-code interface and high-code APIs, PiML supports a growing list of inherently interpretable ML models:
- GLM: Linear/Logistic Regression with L1 โจ L2 Regularization
- GAM: Generalized Additive Models using B-splines
- Tree: Decision Tree for Classification and Regression
- FIGS: Fast Interpretable Greedy-Tree Sums (Tan, et al. 2022)
- XGB1: Extreme Gradient Boosted Trees of Depth 1, with optimal binning (Chen and Guestrin, 2016; Navas-Palencia, 2020)
- XGB2: Extreme Gradient Boosted Trees of Depth 2, with effect purification (Chen and Guestrin, 2016; Lengerich, et al. 2020)
- EBM: Explainable Boosting Machine (Nori, et al. 2019; Lou, et al. 2013)
- GAMI-Net: Generalized Additive Model with Structured Interactions (Yang, Zhang and Sudjianto, 2021)
- ReLU-DNN: Deep ReLU Networks using Aletheia Unwrapper and Sparsification (Sudjianto, et al. 2020)
PiML also works for arbitrary supervised ML models under regression and binary classification settings. It supports a whole spectrum of outcome testing, including but not limited to the following:
- Accuracy: popular metrics like MSE, MAE for regression tasks and ACC, AUC, Recall, Precision, F1-score for binary classification tasks.
- Explainability: post-hoc global explainers (PFI, PDP, ALE) and local explainers (LIME, SHAP).
- Fairness: disparity test and segmented analysis by integrating the solas-ai package.
- WeakSpot: identification of weak regions with high residuals by slicing techniques.
- Overfit: identification of overfitting regions according to train-test performance gap.
- Reliability: assessment of prediction uncertainty by split conformal prediction techniques.
- Robustness: evaluation of performance degradation under covariate noise perturbation.
- Resilience: evaluation of performance degradation under different out-of-distribution scenarios.

from piml import Experiment
exp = Experiment()
exp.data_loader()
exp.data_summary()
exp.data_prepare()
exp.feature_select()
exp.eda()
exp.model_train()
exp.model_explain()
exp.model_interpret()
exp.model_diagnose()
exp.model_compare()
For example, train a complex LightGBM with depth 7 and register it to the experiment:
from lightgbm import LGBMRegressor
pipeline = exp.make_pipeline(LGBMRegressor(max_depth=7))
pipeline.fit()
exp.register(pipeline=pipeline, name='LGBM')
Then, compare it to inherently interpretable models (e.g. EBM and GAMI-Net):
exp.model_compare()
