Dr. Ahn is invited to give a lecture on reinforcement learning on Sep 12, 2018, and a 3hr practical course on computational modeling including a demonstration of the hBayesDM package on Sep 14, 2018 at the Computational Psychiatry Course, which is organized by the Translational Neuromodeling Unit (TNU), Zürich. The 3hr practical course on 9/14 (Friday) will briefly cover the “nuts and bolts” of building and evaluating mathematical models of cognition. In a progressive way, I will teach how to program codes and fit the same computational models with maximum likelihood estimation (MLE), hierarchical Bayesian parameter estimation using Stan, and finally hBayesDM. Through the practical course, participants will learn the pros and cons of each method and how to apply the methods to their research projects.
