ISIPTA 2025

Welcome to the 14th International Symposium on Imprecise Probabilities: Theories and Applications - ISIPTA 2025

ISIPTA is the leading international forum for theories and applications of imprecise probabilities.

The symposium welcomes contributions on all aspects of imprecise probabilities, a broad term for various mathematical and statistical models and methods that allow us to quantify chance or uncertainty without the limitation of sharp probabilities. This includes (but is 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.

The biennial ISIPTA conferences, organized by the Society for Imprecise Probability: Theories and Applications, have been held since 1999, with a focus on presenting and discussing recent developments in the field of imprecise probabilities. The idea of imprecision in probability dates back to Boole in the mid-19th century. Before this conference series, it was developed in a fragmented manner across various fields, including economics, decision making, statistical inference, artificial intelligence, reliability, psychology, and medicine. 

ISIPTA has provided a platform where the differences and similarities between alternative approaches can be better understood, fostering a more unified development of the theory. 

The conference enforces an open environment where interaction and confrontation of ideas are the primary objectives. To achieve this, there will be no parallel sessions, and each accepted paper will be presented both in a plenary session (brief introduction to the main ideas) and in a poster session (for detailed discussion). There will also be the option of presenting ongoing research or preliminary results in a poster, accompanied by a one-page abstract.

We look forward to welcoming you in Bielefeld!
