The International Symposium on Imprecise Probabilities: Theories and Applications is the premier international event dedicated to the exploration of imprecise probabilities, providing a platform for both theoretical advancements and practical applications. The 14th edition of this biennial conference series will be held at the Bielefeld University Center for Interdisciplinary Research from Tuesday, July 15, 2025, to Friday, July 18, 2025.

We invite contributions on all aspects of imprecise probabilities, a term encompassing a wide range of mathematical and statistical models that quantify uncertainty without the restriction of precise probabilities. Topics of interest include, but are not limited to, sets of probability measures, partial preference orderings, game-theoretic probability, choice functions, interval probabilities, risk measures, nonlinear expectations, belief functions, and possibility theory.

As is tradition at ISIPTA, accepted contributions will be presented and discussed in two separate sessions. Presentations are short and plenary. Detailed explanations and discussions are face-to-face relying on whichever medium you prefer – but having a poster is encouraged – so as to favour interaction among participants.

We accept two types of submissions: full papers and one-page abstracts. The submission deadlines are February 2nd, 2025 for full papers and April 27th, 2025 for one-page abstracts; additional important dates like notification of paper acceptance will be communicated in due course. Submission is through the EasyChair platform following the instructions on the conference website for formatting guidelines.
All contributions will be made available on the conference website. Papers will be published in the Proceedings of Machine Learning Research, although authors have the option to opt out of publication.

Registration is free for non-tenured scholars with accepted submission, and € 200 for tenured faculty with accepted submission. The fee for scholars without accepted submission and industry participants is € 600. The registration fee includes lunch, coffee breaks, social dinner, and participation in the social event. Registration is up to June 1st, 2025, but we encourage participants to register only after a final decision on their submission has been made.

We look forward to welcoming you to Bielefeld!
