Compositional Structures in Probabilistic Modeling (CSPM)


The scope of the seminar encompasses compositional structures such as, but not limited to, graphs, hypergraphs, posets, and their representations (functors, sheaves) but also operads and their use for and interaction with probabilistic modeling, for example, in machine learning, deep learning, reinforcement learning, multi-agent systems, games, etc. The aim of the seminar is to stay updated on novel findings around modeling, theoretical developments, and algorithms for compositional structures in probabilistic modeling.
