The BAYST workshop aims to bridge recent advances in Bayesian structural learning with applied sciences, fostering scientific discussion and collaboration between theoretical and applied researchers. BAYST will consist of 20 invited talks (with discussion) and 2 poster sessions (submissions are open!) over two and a half days. Registration is free for all attendees. Coffee breaks, a welcome reception, and lunches will be provided for presenters (of either a poster or a talk). Moreover, BAYST will serve as the kick-off meeting for a potential new section in the International Society of Bayesian Analysis (ISBA) that will be officially proposed to the ISBA Executive Committee after the workshop. The section on Bayesian Structural Learning (BSL) aims to provide an inclusive home for researchers working with high-dimensional or structurally complex data, whether their focus is methodological or applied. Initial officers would be David Dunson, Nadja Klein, Rodney Sparapani, and Deborah Sulem. If you are interested in supporting this initiative, contact us at kleinlab@scc.kit.edu to sign our petition.
