article on preferences and choices learning
by Alessio Benavoli May 9, 2026

May 9, 2026

Dear SIPTA colleagues, I'd like to share with you our recent publication on the prestigious journal Foundations and Trends in Machine Learning, Benavoli A, Azzimonti D (2026), “A tutorial on learning from preferences and choices with Gaussian processes <https://www.emerald.com/ftmal/article-abstract/19/1/1/1360815/A-tutorial-on…> ”. The PDF is also here https://arxiv.org/pdf/2403.11782 which focuses on learning utility functions from preferences and choices data to predict future preferences/choices of a subject based on her past behavior. We use choice functions to model a subject who must select from items that may be incomparable due to trade-offs, leading to imprecise models. We discuss rationality and deviations from rationality. Using simple running examples, we explain the choice situations the decision-maker faces and the various models. Finally, Chapter 6 focuses on real-applications of the introduced models, including the use of preferences to predict tennis match results. I hope you enjoy reading it. Best regards, Alessio

BELIEF 2026: extended submission deadline May 31, 2026
by David Mercier April 18, 2026

April 18, 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.

PhD position in artificial intelligence for fisheries resource management
by Sébastien Ramel March 30, 2026

March 30, 2026

* TITLE Evidential prediction uncertainty quantification for fish life traits from 3D otolith images * THEME Artificial Intelligence, Machine Learning, Data Science * KEYWORDS Dempster-Shafer theory, uncertainty quantification, life traits, marine ecosystems, otolith. * STARTDATE AND DURATION September/October 2026, 36 months * FUNDING 50% IFSEA / 50% Artois University (requested) * LOCATION The work will be carried out in collaboration between the Laboratory of Computer Engineering and Automation of Artois (LGI2A) in Béthune and the Laboratory of Informatics, Signal and Image of the Opal Coast (LISIC) in Calais. * SUBJECT Understanding fish life traits (habitat, age, growth, reproduction, longevity, position in the water column, …) is an essential aspect of effective and sustainable management of marine fish stocks. Calcified structures — particularly otoliths, which are the only metabolically inert elements — provide a valuable source of information for this purpose. Notably, their external shape, historically characterized from 2D images and more recently studied in 3D, makes it possible to predict these life traits with high precision. Although 3D images are more informative, they are also more costly to acquire and relatively recent, and therefore less abundant. It is thus necessary to make the best possible use of this rich yet limited source of information in order to obtain the most reliable and accurate predictions. The theory of evidence, also known as Dempster–Shafer theory or the theory of belief functions, is a generalization of the probabilistic framework for reasoning under uncertainty. Its use for uncertainty quantification in predictive modeling is particularly suitable in cases where data are scarce. This PhD project therefore aims to develop predictive methods based on this theory and adapted to current approaches for predicting fish life traits from 3D otolith images. Given the nature of this application, the prediction of ordinal variables will be at the core of the methodological developments. More detail available here: https://www.lgi2a.univ-artois.fr/spip/en/open_positions/open-position-32 * SUPERVISION Supervisor: Prof. Frédéric Pichon (frederic.pichon(a)univ-artois.fr) Artois University, LGI2A Co-supervisor: Prof. Emilie Poisson Caillault (emilie.caillault(a)univ-littoral.fr) University of the Littoral Opal Coast (ULCO), LISIC Scientific advisor: Dr. Sébastien Ramel (sebastien.ramel(a)univ-artois.fr) Artois University, LGI2A * PROFILE SOUGHT The candidate must hold a master degree or an engineer degree in computer science, applied mathematics or related field. Knowledge in artificial intelligence (machine learning) and/or image processing will be an asset, as well as an awareness of uncertainty management methods. Qualities required to successfully complete a doctoral program such as curiosity, creativity, autonomy, critical thinking, and enthusiasm will be necessary. * APPLICATION Send *before April 30, 2026* an e-mail, with all supervisors of the thesis in copy, containing the following documents in a single pdf file: your CV, a cover letter, your transcripts (with rankings) of the current year (master or equivalent) and previous years, and, optionally, up to two letters of recommendation.
