PGM 2018 Best Student Paper Award

Kari Rantanen, PhD student in the Constraint Reasoning and Optimization Group, received the Best Student Paper Award at PGM 2018, 9th International Conference on Probabilistic Graphical Models.

Kari Rantanen received the PGM 2018 Best Student Paper Award for the paper Learning Optimal Causal Graphs with Exact Search, co-authored with Antti Hyttinen and Matti Järvisalo, and with Kari as the first author. The paper presents the first truly specialized exact search algorithm for optimal causal graphs in a general model space, allowing both cycles and latent confounding variables, and combining problem-specific branch-and-bound style search with linear programming based bounding. The resulting system bcause constitutes empirically a new state-of-the-art approach to the problem.
