[summer school] PrefStat 2025 in Oslo: schedule announced & early-bird extended
by Valeria Vitelli 16 Apr '25

16 Apr '25

Dear all, A *tentative schedule* for the PrefStat summer school 2025 is now announced! Find out more here <https://www.prefstat.org/schedule/>. *Early-bird registration deadline* is now also postponed to **** April 30th, 2025 **** *Preference Statistics summer school* Detailed information on the website <https://www.integreat.no/events/public-events/workshops/prefstat-summer-sch…> Dates: *June 30th - July 4th, 2025* Place: Blindern, *University of Oslo*, Niels Henrik Abels building *Target audience* Researchers in the area of data science, machine learning, statistics, and related fields. Master students with basic skills in machine learning and statistics are also welcome. PrefStat aims to provide participants with a solid foundation in preference learning, and to equip them with the skills and knowledge necessary to apply these methods to real-world problems. *Course description* The PrefStat summer school is a high-level course on cutting-edge topics in the specific context of Statistical Learning from Preference Information, or Preference Learning. The course is designed to provide a comprehensive overview of preference statistics, a rapidly growing field that has gained significant attention in recent years due to the numerous application fields involving human preferences: recommender systems, Large Language Models, surveys and psychological experiments, marketing, economics, and political science. Preference learning is concerned with all data analyses involving preferences, rankings, ratings, clicking, or any kind of ordinal data. It entails modeling experiments involving a set of assessors (experts, judges, users) who express order relations about a set of items, thus being a subfield of both supervised and unsupervised statistical learning. The school provides a deep introduction to the topic and insight into more challenging tasks that are of interest in modern applications, such as handling partial, unstructured, exogenous information, individual preference prediction, and importance feature selection. PrefStat 2025 combines lectures delivered by internationally leading scholars on the specific designated topic and supervised practical tutorials. Feel free to contact us (ccied) for inquiries. We are happy to welcome you to Oslo in June! Warm regards and Happy Easter, Valeria -- Valeria Vitelli Oslo Centre for Biostatistics and Epidemiology, Department of Biostatistics, University of Oslo, Norway group page: https://www.med.uio.no/imb/english/research/groups/statistics-high-dimensio… <https://www.med.uio.no/imb/english/research/groups/statistics-high-dimensio…> mailto: valeria.vitelli(a)medisin.uio.no

OWABI - Ayush Bharti - April 24
by Massimiliano Tamborrino 15 Apr '25

15 Apr '25

Dear all, the next OWABI seminar<http://www.warwick.ac.uk/oneworldabc> is scheduled on Thursday the 24th April at 11am UK time. Our next speaker is Ayush Bharti (Aalto University), who will talk about "Cost-aware simulation-based inference ", with an abstract reported below. The talk will be exceptionally streamed on Zoom https://chalmers.zoom.us/j/67207457257 (password 201659), Abstract: Simulation-based inference (SBI) is the preferred framework for estimating parameters of intractable models in science and engineering. A significant challenge in this context is the large computational cost of simulating data from complex models, and the fact that this cost often depends on parameter values. We therefore propose cost-aware SBI methods which can significantly reduce the cost of existing sampling-based SBI methods, such as neural SBI and approximate Bayesian computation. This is achieved through a combination of rejection and self-normalised importance sampling, which significantly reduces the number of expensive simulations needed. Our approach is studied extensively on models from epidemiology to telecommunications engineering, where we obtain significant reductions in the overall cost of inference. Keywords: simulation-based inference, approximate Bayesian computation, neural posterior estimation, neural likelihood estimation, importance sampling In the meantime, enjoy the Easter break. Best, Massimiliano on the behalf of the OWABI Organisers ------ Dr. Massimiliano Tamborrino Reader (Associate Professor) and WIHEA Fellow Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino

Saluti Alessandra ---------- Forwarded message --------- From: Teta, Alessandro <teta(a)mat.uniroma1.it> %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Avviso di seminario di Matematica, Scienza & Società Lunedì 14 aprile 2025, alle ore 17.00 Aula Picone del Dipartimento di Matematica G. Castelnuovo di Sapienza Università di Roma *Riccardo Adami (Politecnico di Torino)La seconda rivoluzione quantistica: il gatto ci spia ma il collasso ci protegge* Sommario Oltre alla fisica e alla matematica, la Meccanica Quantistica ha rivoluzionato le esistenze degli uomini e delle donne, rendendo possibili dispositivi prima impensabili: le invenzioni del transistor, del laser e del led sono tre dei passaggi chiave della cosiddetta “rivoluzione tecnologica quantistica”. Oggi siamo alla vigilia della seconda rivoluzione, che sarà segnata dalla realizzazione del computer quantistico e di altre nuove tecnologie. Una novità della seconda rivoluzione è che essa si realizzerà nel segno della semplicità: invece di essere sistemi composti da molte particelle, i nuovi dispositivi sfrutteranno le caratteristiche quantistiche delle singole particelle. Siccome è proprio nei sistemi semplici che entra in gioco la stranezza del mondo quantistico, la progettazione delle nuove tecnologie sta riaprendo il dibattito sulla visione del mondo che origina dalla meccanica quantistica. Esploreremo alcune delle questioni filosofiche ritornate di attualità, anche alla luce delle applicazioni a una scienza ormai pervasiva quanto necessaria: la crittografia.

Fwd: promemoria seminario Makiko Sasada
by Faggionato, Alessandra 11 Apr '25

Ricevo e con piacere inoltro. Il seminario e' tra meno di 2h Buona giornata Alessandra ---------- Forwarded message --------- From: Basile, Giada <basile(a)mat.uniroma1.it> Date: Fri, 11 Apr 2025 at 09:18 Subject: promemoria seminario Makiko Sasada Care e cari, vi ricordo che oggi alle 16:15 ci sarà il seminario di Makiko Sasada. Titolo: Discrete geometric structure of large-scale interacting systems Abstract. In this talk, we explore large-scale interacting systems that explain macroscopic phenomena through the movement of microscopic particles. These systems are modeled by discrete lattices where microscopic dynamics occur and the transitions between adjacent sites, referred to as “interactions” in our definition. We classify interactions based on conserved quantities, which reflect macroscopic properties, and introduce wedge sums and box products as methods to construct new interactions from existing ones. We also present a discrete harmonic theory for large-scale interacting systems on discrete lattices with finite local state sets. By assuming exchangeable interactions, we define the inverse harmonic period matrix, which we expect to correspond to the diffusion matrix in the hydrodynamic limit. Our result offers an interpretation of the diffusion matrix based on the geometry of the microscopic model.
