Dive into Bayesian networks with our Introductory BayesiaLab Course: Theory matched with hands-on sessions for applied researchers.
About this Event

The renowned Introductory BayesiaLab Course offers an in-depth exploration of Bayesian networks, equipping you to harness them for applied research in fields like biostatistics, marketing science, ecology, and beyond.

What sets this course apart is its hands-on approach: every theoretical module is complemented by a practical BayesiaLab session. So, as you delve into topics like knowledge modeling, causal inference, and machine learning, you can immediately apply your learning on your computer.

For many of the 2,000 or so course participants from around the world to date, Bayesian networks and BayesiaLab indispensable in their work.


<h4>About the Instructor</h4>

Dr. Lionel Jouffe is co-founder and CEO of France-based Bayesia S.A.S. Lionel holds a Ph.D. in Computer Science from the University of Rennes and has worked in Artificial Intelligence since the early 1990s. While working as a Professor/Researcher at ESIEA, Lionel started exploring the potential of Bayesian networks.

After co-founding Bayesia in 2001, he and his team have been working full-time on the development of BayesiaLab, which has since emerged as the leading software package for knowledge discovery, data mining, and knowledge modeling using Bayesian networks. BayesiaLab enjoys broad acceptance in academic communities, business, and industry.
