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 package that incorporates state-of-the-art machine learning interpretability techniques under one roof. With this package, you can train interpretable glassbox models and explain blackbox systems. InterpretML helps you understand your model's global behavior, or understand the reasons behind individual predictions.

Interpretability is essential for:

  • Model debugging - Why did my model make this mistake?
  • Feature Engineering - How can I improve my model?
  • Detecting fairness issues - 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, ...

Installation

Python 3.7+ | Linux, Mac, Windows

pip install interpret
# OR
conda install -c conda-forge interpret

Introducing the Explainable Boosting Machine (EBM)

EBM is an interpretable model developed at Microsoft Research*. It uses modern machine learning techniques like bagging, gradient boosting, and automatic interaction detection to breathe new life into traditional GAMs (Generalized Additive Models). This makes EBMs as accurate as state-of-the-art techniques like random forests and gradient boosted trees. However, unlike these blackbox models, EBMs produce exact explanations and are editable by domain experts.

Train a glassbox model

Let's fit an Explainable Boosting Machine

from interpret.glassbox import ExplainableBoostingClassifier

ebm = ExplainableBoostingClassifier()
ebm.fit(X_train, y_train)

# or substitute with LogisticRegression, DecisionTreeClassifier, RuleListClassifier, ...
# 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)

Global Explanation Image


Understand individual predictions

ebm_local = ebm.explain_local(X_test, y_test)
show(ebm_local)

Local Explanation Image


And if you have multiple model explanations, compare them

show([logistic_regression_global, decision_tree_global])

Dashboard Image


If you need to keep your data private, use Differentially Private EBMs (see DP-EBMs)

from interpret.privacy import DPExplainableBoostingClassifier, DPExplainableBoostingRegressor

dp_ebm = DPExplainableBoostingClassifier(epsilon=1, delta=1e-5) # Specify privacy parameters
dp_ebm.fit(X_train, y_train)

show(dp_ebm.explain_global()) # Identical function calls to standard EBMs


For more information, see the documentation.


EBMs include pairwise interactions by default. For 3-way interactions and higher see this notebook: https://interpret.ml/docs/python/examples/custom-interactions.html


Interpret EBMs can be fit on datasets with 100 million samples in several hours. For larger workloads consider using distributed EBMs on Azure SynapseML: classification EBMs and regression EBMs
