(Not so random) new post on the SIPTA blog (on randomness and imprecision)
by Alexander Erreygers April 28, 2025

April 28, 2025

Dear imprecise probabilities enthusiasts, Ever thought about the question “when can/should one call an infinite sequence of 0s and 1s random”? You’re not alone! While you may have never thought about this question for more than a couple of minutes, hours or days, Floris Persiau spent about 5 years thinking about this question, over the course of obtaining his doctoral degree. Curious about his way of thinking about this problem (which, of course, included allowing for imprecision), and curious to find out whether he managed to come up with a satisfactory answer? Head over to the SIPTA blog now, where Floris Persiau is handing out small bites of the big cake that is his doctoral dissertation — all for free, no strings attached. Kind regards, Alexander Erreygers

ISIPTA 2025: call for poster submissions (submission deadline: 5 may)
by sdesterc April 24, 2025

April 24, 2025

*** The organizers would be grateful if you could inform potentially interested participants of this conference. *** ================================================================ 14th International Symposium on imprecise probabilities: theories and applications (ISIPTA 2015) Call for posters The ISIPTA 2025 conference will take place between July 15 and July 18 in Bielefeld, Germany. It will welcome researchers working on imprecise probability theories and connected fields from all over the world, to discuss recent advancements. If you did not have the time to submit a paper, there is still time to submit a poster abstract. This will not only allow you to actively participate in the event, but will also enable you to register at a reduced fee or, if you are a non-tenured scholar, to register for free. Following past ISIPTA traditions, poster submissions will receive substantial attention: each poster is presented at a plenary session as well as at the poster session that follows it, alongside the regular full paper contributions. We therefore encourage you to submit your work as a poster. This could be work in progress that you’d like to present or get feedback on, as well as existing published material that you’d like to present to the ISIPTA audience. Submissions consist of a one page abstract that summarizes the work to be presented. The deadline for poster submissions is May 5, 2025. Acceptance of poster submissions will be notified shortly after the submission. The ISIPTA steering committee • Jasper De Bock • Sébastien Destercke • Alexander Erreygers • Max Nendel • Frank Riedel • Matthias Troffaes ================================================================

Next SIPTA seminar, Krikamol Muandet on 24th April 15h Paris time, "Imprecise generalisation"
by sdesterc April 17, 2025

April 17, 2025

Dear colleagues, We are delighted to announce our upcoming SIPTA online seminar on imprecise probabilities (IP). These monthly events are open to anyone interested in IP, and will be followed by a Q&A and open discussion. They also provide an occasion for the community to meet, keep in touch and exchange between in-person events. The next seminar will take place on the 24th of April (Thursday). The zoom link for this seminar is https://utc-fr.zoom.us/j/88932866889 For this new seminar, we are very happy to have Krikamol Muandet as our speaker. Krikamol Muandet is currently a chief scientist and tenure-track faculty (fast track) at CISPA - Helmholtz Center for Information Security which is within the Helmholtz Association where he leads the Rational Intelligence (RI) Lab. While Krikamol prime interest lies in machine learning, a field in which he has many contributions, he has also a strong interest in its intersections with imprecise probabilities, and in particular the idea of imprecision in learning. On the 24th of April at 15:00 CEST:paris time (up to 17:00 CEST, with a talk duration of 45min/1h), he will talk about "Imprecise generalisation”. Curious? Then check out the abstract on the webpage of the SIPTA seminars: sipta.org/events/sipta-seminars. The zoom link for attending the seminar can be found on that same page. So please mark your calendars on the 24th of April, and join us for the occasion.

ISIPTA 2025 - second call for paper
by sdesterc Jan. 17, 2025

Jan. 17, 2025

Dear colleagues, The deadline to submit long papers to ISIPTA, which is the 2nd of February, is fast approaching! The International Symposium on Imprecise Probabilities: Theories and Applications is the premier international event dedicated to the exploration of imprecise probabilities, providing a platform for both theoretical advancements and practical applications. ISIPTA also has a strong tradition of favouring discussions among its participants. To do so, accepted contributions will be presented and discussed in two separate sessions. The first session features presentations that are short and plenary. The second, longer session is devoted to detailed explanations and discussions that are face-to-face and rely on whichever medium you prefer – but having a poster is encouraged – so as to favour interaction among participants. ISIPTA will also welcome a number of renowned keynote speakers: • Carole Bernard (Grenoble École de Management & Vrije Universiteit Brussel) • Itzhak Gilboa (Hautes Études Commerciales de Paris) • Peter Grünwald (Centrum Wiskunde & Informatica & Leiden University) • Jan Obłój (University of Oxford) We invite contributions on all aspects of imprecise probabilities, a term encompassing a wide range of mathematical and statistical models that quantify uncertainty without the restriction of precise probabilities. Topics of interest include, but are 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. We accept two types of submissions: full papers and one-page abstracts. The submission deadlines are February 2nd, 2025 for full papers and April 27th, 2025 for one-page abstracts; additional important dates like notification of paper acceptance will be communicated in due course. Submission is through the EasyChair platform following the instructions on the conference website for formatting guidelines. All contributions will be made available on the conference website. Papers will be published in the Proceedings of Machine Learning Research, although authors have the option to opt out of publication. Registration is free for non-tenured scholars with accepted submission, and € 200 for tenured faculty with accepted submission. The fee for scholars without accepted submission and industry participants is € 600. The registration fee includes lunch, coffee breaks, social dinner, and participation in the social event. Registration is up to June 1st, 2025, but we encourage participants to register only after a final decision on their submission has been made. We look forward to welcoming you to Bielefeld! The ISIPTA 2025 Steering Committee Jasper De Bock Sébastien Destercke Alexander Erreygers Max Nendel Frank Riedel Matthias Troffaes
