ISIPTA 2023: Second Call For Papers

January 17, 2023

The Thirteenth International Symposium on Imprecise Probabilities: Theories and Applications (ISIPTA 2023)

What if we told you that

“There’s more to uncertainty than probabilities.”

Curious? Then come to Oviedo, Spain, 11-14 July 2023, to attend the 13th edition of ISIPTA: the world’s main forum on imprecise probabilities. For more information, visit

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, belief functions, and possibility theory.

CONCEPT: Each accepted contribution is 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, so as to favor interaction among participants (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. The conference will take place in Oviedo, the capital of Asturias, a region in the north of Spain familiarly referred to as the Natural Paradise. In addition, Oviedo is the original starting point of the primary cultural route in Europe, the Way of St James, and is home to five pre-Romanesque monuments declared World Heritage Sites by UNESCO in 1985 and 1998.

SUBMISSIONS: 2 options are available

  • Papers (with a limit of 9 pages, excluding references);
  • Abstracts (1 page, for ongoing research)

Submission should be done via easychair

PLENARY SPEAKERS: We are proud to announce that the plenary speakers of ISIPTA 2023 shall be:

  • Gert de Cooman (Ghent University, Belgium).
  • Marta Kwiatkowska (University of Oxford, United Kingdom).
  • Michel Grabisch (Université Paris I Panthéon Sorbonne, France).

TRIBUTE TO TERRENCE FINE: During ISIPTA 2023, we will pay tribute to Terrence Fine, one of the founding fathers of imprecise probability theory, who sadly passed away on January 31, 2021. More information shall be provided in due time.

PROCEEDINGS: Papers will be published by PMLR in their Proceedings of Machine Learning Research series. After the conference, extended versions of selected conference contributions will be published in a special issue of the International Journal of Approximate Reasoning.

FELLOWSHIPS: The Artificial Intelligence Journal is funding 4 fellowships for PhD Students. More information on the conditions and applications will be given in due time.

AWARDS: As in previous editions, there will be two types of awards:

On the one hand, the International Journal of Approximate Reasoning will give the IJAR Young Researcher Award to a young researcher whose contributions to IP theory are outstanding. The award shall consist of a certificate and 1000 euros. More details shall be given soon.

In addition, poster awards shall be given to those poster presentations of excellent quality. The award shall be supported by Wiley and Springer and will consist of a certificate and a book.

SIPTA is on twitter now

April 15, 2022

Our beloved society now has a Twitter account: @SIPTAtweets. Just like our mailing list, the aim of this twitter feed is to rapidly disseminate information related to imprecise probabilities and SIPTA. Follow us, and we’ll keep you posted.

Are you tweeting about things related to imprecise probabilities yourself? Mention @SIPTAtweets in your tweet, and perhaps we’ll share it with the rest of the imprecise probabilities community.

Our thanks goes out to Ullrika Sahlin, who offered to manage the account. For questions related to our Twitter account, you can mail us at
