What if we told you that

���There���s more to uncertainty than probabilities.���

Would you agree? Would you object? Are you intrigued? Regardless of the answer, you have a place at, and are invited to submit a paper to, ISIPTA 2019, the 20-year anniversary edition of the world���s main forum on imprecise probabilities.

Already convinced? Then come to Ghent, Belgium, 3-6 July 2019, and take a look at the following website for any and all details you might require: http://isipta2019.ugent.be.

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

Topic: ISIPTA 2019 is 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.

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, with the aid of a poster, a whiteboard, pen and paper, or whichever medium you prefer.

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

Venue: Ghent has been called ���Belgium���s best kept secret��� by the Lonely Planet travel guide and a ���medieval masterpiece��� by The Guardian. The conference itself takes place in an old Augustinian monastery, situated in its historic city centre.

Types of contributions: We accept long papers, short papers and poster abstracts. Papers are published in a volume of PMLR, unless explicitly preferred otherwise by their authors.

We look forward to receiving your contribution and/or to seeing you in Ghent!

Sincerely,

The ISIPTA 2019 Steering Committee and PC board
