Bnlearn is for causal discovery using in Python!

• Contains the most-wanted Bayesian pipelines for Causal Discovery

• Simple and intuitive

• Focus on structure learning, parameter learning and inference.

---

Support

Yes! This library is entirely free but it runs on coffee! :)

---

Tip

• Detecting causal relationships using Bayesian Structure Learning in Python.

• Designing knowledge-driven models using Bayesian theorem.

• Chat with Your Dataset using Bayesian Inferences.

• The Power of Bayesian Causal Inference: A Comparative Analysis of Libraries to Reveal Hidden Causality in Your Dataset.

• Find the Best Boosting Model using Bayesian Hyperparameter Tuning but without Overfitting.
