InterpretML - Alpha Release
In the beginning machines learned in darkness, and data scientists struggled in the void to explain them.
Let there be light.
InterpretML is an open-source python package for training interpretable models and explaining blackbox systems. Interpretability is essential for:
- Model debugging - Why did my model make this mistake?
- Detecting bias - Does my model discriminate?
- Human-AI cooperation - How can I understand and trust the model's decisions?
- Regulatory compliance - Does my model satisfy legal requirements?
- High-risk applications - Healthcare, finance, judicial, ...
Historically, the most intelligible models were not very accurate, and the most accurate models were not intelligible. Microsoft Research has developed an algorithm called the Explainable Boosting Machine (EBM)* which has both high accuracy and intelligibility. EBM uses modern machine learning techniques like bagging and boosting to breathe new life into traditional GAMs (Generalized Additive Models). This makes them as accurate as random forests and gradient boosted trees, and also enhances their intelligibility and editability.

In addition to EBM, InterpretML also supports methods like LIME, SHAP, linear models, partial dependence, decision trees and rule lists. The package makes it easy to compare and contrast models to find the best one for your needs.
Python 3.5+ | Linux, Mac OS X, Windows
pip install -U interpret
Let's fit an Explainable Boosting Machine
from interpret.glassbox import ExplainableBoostingClassifier ebm = ExplainableBoostingClassifier() ebm.fit(X_train, y_train) # EBM supports pandas dataframes, numpy arrays, and handles "string" data natively.
Understand the model
from interpret import show ebm_global = ebm.explain_global() show(ebm_global)
Understand individual predictions
ebm_local = ebm.explain_local(X_test, y_test) show(ebm_local)
And if you have multiple models, compare them
- Interpretable models for binary classification
- Interpretable models for regression
- Blackbox interpretability for binary classification
- Blackbox interpretability for regression
Currently we're working on:
- Multiclass Classification Support
- Missing Values Support
- Improved Categorical Encoding
...and lots more! Get in touch to find out more.

If a tree fell in your random forest, would anyone notice?
