SIPTA virtual seminar on 6th May (3pm CEST): Marnix Sulien on Robust Markov Decision Processes
by Sebastien Destercke April 30, 2026

April 30, 2026

Dear colleagues, We are delighted to announce our upcoming SIPTA online seminar on imprecise probabilities (IP). These monthly events are open to anyone interested in IP, and will be followed by a Q&A and open discussion. They also provide an occasion for the community to meet, keep in touch and exchange between in-person events. The next seminar will take place on the 6th of May (Wednesday). The zoom link for this seminar is https://utc-fr.zoom.us/j/82696376560 For this new seminar, we are very happy to have Marnix Suilen as our speaker. Marnix Suilen is currently a postdoctoral researcher in the AnSyMo group at the University of Antwerp. His research focuses on decision-making under uncertainty, in particular planning and reinforcement learning (RL). In this setting, Marnix has obtained strong results on Robust POMDPs and other models using imprecise probabilities, published in top-tier venues such as IJCAI, AAAI, or NEURIPS. On the 6th of May, at 15:00 CEST:paris time (up to 17:00 CEST, with a talk duration of 45min/1h), he will talk about "Robust Partially Observable Markov Decision Processes: Decision-Making Under State Uncertainty and Imprecise Probabilities”. Curious? Then check out the abstract on the webpage of the SIPTA seminars: sipta.org/events/sipta-seminars. The zoom link for attending the seminar can be found on that same page. So please mark your calendars on the 6th of May, and join us for the occasion. And for those who missed the previous seminar and want to catch up, or simply want to see it again and again, it is online at https://www.youtube.com/watch?v=IUfiJVlJli8 See you at the seminar! Sébastien, Enrique and Jasper

BELIEF 2026: extended submission deadline May 31, 2026

(Our apologies for any duplicate messages) ********************************************************** The 9th International Conference on Belief Functions (BELIEF 2026) https://www.bfasociety.org/Belief2026 Dates: October 19-21, 2026 Location: Nanjing, China * May 31, 2026: Paper submission deadline (extended) * June 15, 2026: Author notification * June 30, 2026: Camera-ready copy due ********************************************************** The Theory of belief functions, also referred to as Evidence theory or Dempster-Shafer theory is a well-established mathematical framework for reasoning and decision-making with uncertainty, with applications to machine learning, statistical inference, information fusion, knowledge representation, risk analysis, etc. It is an extension of probability theory and it has well understood connections with related frameworks such as random sets and imprecise probabilities. Recently, generalised evidence theory, based on random fuzzy sets, has been proposed as a unifying framework encompassing both Dempster-Shafer and possibility theories. The biennial BELIEF conferences (sponsored by the Belief Functions and Applications Society) are dedicated to the confrontation of ideas, the reporting of recent achievements and the presentation of the wide range of applications of this theory. Previous editions of this conference series were held in Brest, France (2010); Compiègne, France (2012); Oxford, UK (2014); Prague, Czech Republic (2016); Compiègne, France (2018); Shanghai, China (2021); Paris, France (2022), and Belfast, UK (2024). To support cross-fertilization among researchers working in different subfields of AI and related disciplines, tutorials and special sessions will be proposed, with emphasis on the links between machine learning, statistical inference and uncertain reasoning, including topics such as quantification of prediction uncertainty, fusion rules for ensemble learning, belief propagation in deep neural networks, links with explainable and symbolic AI, etc. Submissions of papers combining several of these topics, or more generally at the cross-road of belief functions and other AI methods or uncertainty theories, along with relevant applications, are welcome. Proceedings BELIEF 2026 proceedings will be published by Springer-Verlag in the Lecture Notes in Artificial Intelligence (LNCS/LNAI) series and indexed by: ISI Web of Science; EI Engineering Index; ACM Digital Library; dblp; Google Scholar; IO-Port; MathSciNet; Scopus; Zentralblatt MATH. IJAR Special issue Authors of selected papers from the BELIEF 2026 conference will be invited to submit extended versions of their papers for possible inclusion in a special issue of the International Journal of Approximate Reasoning.
