A Survey of 10 Python Libraries for Explainable AI (XAI)

XAI (Explainable AI) aims to provide meaningful explanations for the behavior and decisions of AI models, increasing trust, accountability, and transparency, especially in high‑risk domains such as healthcare, finance, and criminal justice.

What is XAI?

Explainable AI refers to systems or strategies that can offer clear, understandable explanations for AI decision‑making processes and predictions. It not only explains outcomes but also facilitates easier reasoning for users during ML experimentation.

In practice, XAI can be realized through feature‑importance metrics, visualization techniques, or inherently interpretable models such as decision trees or linear regression. The choice of method depends on the problem type and the required level of interpretability.

Steps for an Explainability Practice

Data preparation: Collect and process high‑quality, balanced data that represents the real‑world problem.

Model training: Train traditional ML models or deep‑learning networks on the prepared data; simpler models are easier to interpret but may have lower performance.

Model evaluation: Choose appropriate evaluation methods and metrics, and assess the model’s explainability alongside performance.

Explanation generation: Use techniques such as feature‑importance measures, visualizations, or inherently interpretable models.

Explanation validation: Verify the accuracy and completeness of generated explanations to ensure trustworthiness.

Deployment and monitoring: Continue explainability work after deployment, monitoring both performance and interpretability in real environments.

1. SHAP

(SHapley Additive exPlanations) – a game‑theoretic method that explains the output of any ML model by allocating credit using Shapley values.

2. LIME

(Local Interpretable Model‑agnostic Explanations) – a model‑agnostic technique that approximates the behavior of a model locally around a specific prediction, supporting text, tabular, and image classifiers.

3. ELI5

ELI5 is a Python package that helps debug and explain machine‑learning classifiers. It supports scikit‑learn, Keras (via Grad‑CAM), XGBoost, LightGBM, CatBoost, lightning, and sklearn‑crfsuite, among others.

Basic usage:

<code>Show_weights()</code>

displays all model weights, and

<code>Show_prediction()</code>

checks individual predictions.

4. Shapash

Shapash offers several visualizations to make model decisions easier to understand, integrating smoothly with Jupyter/IPython.

<code>from shapash import SmartExplainer
xpl = SmartExplainer(model=regressor, preprocessing=encoder, features_dict=house_dict)
xpl.compile(x=Xtest, y_pred=y_pred, y_target=ytest)
xpl.plot.contribution_plot("OverallQual")
</code>

5. Anchors

Anchors generate high‑precision rules (anchors) that explain complex model behavior locally, offering a lightweight alternative to SHAP.

6. BreakDown

BreakDown explains linear model predictions by decomposing the output into contributions from each input feature.

<code>model = tree.DecisionTreeRegressor()
model = model.fit(train_data, y=train_labels)
# necessary imports
from pyBreakDown.explainer import Explainer
from pyBreakDown.explanation import Explanation
exp = Explainer(clf=model, data=train_data, colnames=feature_names)
explanation = exp.explain(observation=data[302, :], direction="up")
</code>

7. Interpret‑Text

Interpret‑Text combines community‑developed XAI techniques for NLP models with visual dashboards, supporting global and local explanations for text classification.

<code>from interpret_text.widget import ExplanationDashboard
from interpret_text.explanation.explanation import _create_local_explanation
local_explanantion = _create_local_explanation(
    classification=True,
    text_explanation=True,
    local_importance_values=feature_importance_values,
    method=name_of_model,
    model_task="classification",
    features=parsed_sentence_list,
    classes=list_of_classes,
)
ExplanationDashboard(local_explanantion)
</code>

8. AI Explainability 360 (aix360)

IBM’s open‑source AI Explainability 360 toolkit provides a comprehensive suite of algorithms and metrics for model interpretability across various dimensions.

9. OmniXAI

OmniXAI is a one‑stop Python library for XAI, offering both global and local explanations, dashboards, and support for various model types including CUDA‑accelerated, RNN, and BERT.

<code>from omnixai.visualization.dashboard import Dashboard
dashboard = Dashboard(
    instances=test_instances,
    local_explanations=local_explanations,
    global_explanations=global_explanations,
    prediction_explanations=prediction_explanations,
    class_names=class_names,
    explainer=explainer,
)
dashboard.show()
</code>

10. XAI (eXplainable AI)

The XAI library, maintained by The Institute for Ethical AI & ML, follows the eight principles of Responsible Machine Learning and is currently in alpha, not recommended for production.
