The Twelfth International Symposium on Imprecise Probability: Theories and Applications (ISIPTA 2021)

What if we told you that

"There's more to uncertainty than probabilities".

Would you agree? Then attend the 12th edition of ISIPTA: the world’s main forum on imprecise probabilities.

Not convinced yet? Then perhaps the following features can convince you:

TOPIC: The symposium is open to contributions on all aspects of imprecise probability, including (but not limited to) sets of probability measures, partial preference orderings, game-theoretic probability, choice functions, interval probabilities, lower and upper previsions, belief functions, and possibility theory.

CONCEPT: Even though attending in person may not be possible, we plan to keep the spirit of past ISIPTA conferences. Each accepted contribution will therefore be presented and discussed, in two separate sessions: a plenary session with short presentations, and a poster session devoted to more detailed explanations and discussions. We will make use of online tools to allow for social interaction. Informal meetings of small groups, for example, will be possible. You can visit for links to the previous editions of all ISIPTA conferences.

WHY ATTEND?: The conference is an excellent opportunity to learn about the latest developments in imprecise probability in a friendly and cooperative atmosphere where interaction and confrontation of ideas are the primary objectives. In addition, if Covid-19 allows it, we encourage you to come to Granada, a lively and beautiful city, with treasures such as the Alhambra, but also with its Albaicín Neighborhood, its impressive Cathedral, and its Renaissance and Baroque architecture.
