Structure Learning

---

bnlearn is for learning the graphical structure of Bayesian networks in Python! What benefits does bnlearn offer over other bayesian analysis implementations?

• Build on top of the pgmpy library

• Contains the most-wanted bayesian pipelines

• Simple and intuitive

• Focus on structure learning, parameter learning and inference.
