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

In our call for papers we stated that

"There's more to uncertainty than probabilities".

and tried to convince you that ISIPTA 2021 is a good place for discussing such matters. The paper submission deadline has passed, but rest assured, you can still present your work at ISIPTA, because poster abstract submission is open. These poster abstracts are intended for discussing preliminary results and open questions, or for bringing published results to the attention of the ISIPTA audience.

Each accepted poster abstract will be announced in a one-minute plenary spotlight presentation, and the accompanying poster will be presented at length during one of the discussion sessions. Given the prominent role of poster presentations at ISIPTA, these sessions provide you with a genuine opportunity for presenting your work to the ISIPTA audience.

The deadline for poster submission is May 15. You can submit at any time before that, though, and we will provide you with a decision within two weeks.

Not convinced yet? Then perhaps the following features can persuade you.

BASIC INFO: ISIPTA 2021 will be a virtual conference, but we are also considering the possibility of in person participation (contingent on the Covid-19 situation). It will take place in Granada, Spain, from 6 to 9 July 2021. Additional information is available on our website: The virtual conference will be hosted by Researchers.One.

SCOPE: The ISIPTA conferences are devoted to robustness and imprecision in uncertainty modelling, inference and decision making, focusing in particular on uncertainty frameworks that extend or replace the probabilistic one.

INVITED SPEAKERS: ISIPTA 2021 will feature keynote talks by Elias Bareinboim (Causal Artificial Intelligence Lab, Columbia University, USA), Lars Peter Hansen (Department of Economics, University of Chicago, USA) and Marco Zaffalon (Istituto Dalle Molle di Studi sull'Intelligenza Artificiale (IDSIA), Lugano, Switzerland).

CONCEPT: Each accepted contribution is presented and discussed, in two separate sessions. Presentations are short and always plenary. Detailed explanations and discussions will take place in virtual poster sessions (hosted in Gather Town).

REGISTRATION: Registration will open soon. Being a virtual conference, you can participate with fees as low as 50€ for students and 90€ for other participants.

ATMOSPHERE: ISIPTA conferences are characterised by a friendly and cooperative style, a strong emphasis on in-depth discussion and openness to new ideas. We hope that you too will enjoy and contribute to this unique atmosphere.

AWARDS: ISIPTA 2021 will hand out an IJAR Young Researcher Award (for excellent research in the area of imprecise probabilities) and several poster awards. The IJAR award is sponsored by the International Journal of Approximate Reasoning. The deadline for applying for the IJAR Young Researcher Award is the 1st of June; the rules for application are available on our website. Anyone who presents a poster (either for a paper or poster abstract) is eligible for the poster prizes.
