Two Open PhD Positions – Math for Climate-Resilient Energy Networks (VU Amsterdam)
by Zocca, A. (Alessandro) 23 Apr '25

23 Apr '25

Dear colleagues, I currently have two open PhD positions at Vrije Universiteit Amsterdam as part of a new NWO-funded project at the intersection of applied probability, graph theory, and network optimization. The goal is to develop mathematical foundations for climate-resilient energy systems—a pressing challenge as extreme weather events increasingly threaten the reliability of our power infrastructure. The two positions focus on complementary but distinct aspects of the problem: PhD 1 – Modeling Weather-Driven Failures Develop parsimonious stochastic models using applied probability and graph theory to understand how spatially correlated extreme weather events cause multi-point failures across power grids. PhD 2 – Optimizing Climate-Resilient Grid Operations Design flexible, cost-effective decision-making tools using stochastic optimization and simulation to support smart planning and reconfiguration of energy networks under uncertainty. Both positions are fully funded for 4 years, with a tentative start date in September 2025. The application deadline is May 25, 2025. I’m happy to answer informal questions directly by email, but formal applications must go through the following link: https://workingat.vu.nl/vacancies/phd-positions-in-applied-probability-and-… If you know motivated students or recent graduates with a strong mathematical background and an interest in energy systems, sustainability, and uncertainty modeling, I’d be grateful if you could pass this along. Best, Alessandro Alessandro Zocca (he/his) Assistant Professor Vrije Universiteit Amsterdam Department of Mathematics https://alessandrozocca.github.io/

Reminder: OWABI - Ayush Bharti - April 24
by Massimiliano Tamborrino 23 Apr '25

23 Apr '25

Dear all, a kind reminder of tomorrow's (Thursday the 24th April, 11am UK time) OWABI seminar<http://www.warwick.ac.uk/oneworldabc> by 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 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

Conference in CIRM, Marseille in October 2025: New trends of Stochastic nonlinear systems
by Erika Hausenblas 22 Apr '25

22 Apr '25

We would like to bring to your attention the conference in CIRM - Lumini, Marseille from 20 – 24 October, 2025: New trends of stochastic nonlinear systems: well-posedeness, dynamics and numerics Erika Hausenblas (University of Leoben) Chengcheng Ling (University of Augsburg) Stéphane Menozzi (Université d’Évry) https://conferences.cirm-math.fr/3374.html Stochastic analysis is a very dynamic field which has undergone numerous developments over the last decades: stochastic differential equations (SDE), stochastic partial differential equations (EDPS), Malliavin calculus... In order to study new singular complex models, which in particular arise from regularization/de-regulation by noise-related problems, particle systems, quantum mechanics or machine learning, new ideas have appeared, yielding numerous results concerning the well-posedness, dynamics and approximation of singular ED(P)S in numerous scientific or engineering fields. Among these ideas, we can mention: the application of convex integration techniques for stochastic equations, the sewing lemma to highlight fine regularisation properties of the underlying noise, quantum field theory to help understand quantum dynamics, or the association of classical techniques with tools such as rough paths theory to solve problems which could not be addressed independently. If you would like to participate, please contact one of the organisers or spdescirmmarseille(a)gmail.com.

Tom Kurtz
by c.costantini＠unich.it 22 Apr '25

22 Apr '25

E' con grande tristezza che do l'annuncio della morte, sabato 19 aprile, di Tom Kurtz. Tom ha visitato l'Italia molte volte e molti probabilisti italiani l'hanno conosciuto di persona. Il libro che Tom ha scritto nel 1986 insieme a Stewart Ethier, "Markov processes: characterization and convergence", è tuttora un testo di riferimento. Tom ha scritto anche un altro libro, con Jin Feng, su "Large deviations for stochastic processes". Tom ha dato importantissimi contributi non solo sulla caratterizzazione dei processi di Markov e sui metodi per studiarne la convergenza, e sulla teoria delle grandi deviazioni, ma anche alla teoria del filtraggio, alla teoria dei processi a valori misura, allo studio delle equazioni differenziali stocastiche alle derivate parziali, allo studio dei processi di punto spaziali, alla dinamica delle popolazioni, alla teoria delle diffusioni riflettenti, alla teoria delle reti stocastiche, in particolare per le reazioni chimiche, e in altri campi ancora. Caratteristica di Tom era la sua disponibilità a parlare con tutti, da un collega a un giovanissimo studente, condividendo con grandissima generosità il suo tempo, la sua conoscenza e le sue idee.

Seminario PRISMA lunedì 5 maggio 2025 - C. Orrieri & L. Scarpa
by Sonia Mazzucchi 22 Apr '25

22 Apr '25

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/) I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb Il prossimo appuntamento è per *lunedì 5 maggio 2025*. I relatori saranno *Carlo Orrieri* (Università di Pavia) e *Luca Scarpa* (Politecnico di Milano) che parleranno di: *Equazioni stocastiche doppiamente nonlineari e relativi problemi di regolarizzazione per rumore* con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://unitn.zoom.us/j/88514293418 ID riunione: 885 1429 3418 Codice d’accesso: 236100 Vi aspettiamo numerosi! Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Carlo Orrieri (Università di Pavia) e Luca Scarpa (Politecnico di Milano) TITOLO: Equazioni stocastiche doppiamente nonlineari e relativi problemi di regolarizzazione per rumore RIASSUNTO: Nella prima parte del seminario verranno introdotte alcune classi di equazioni di evoluzione in relazione alla modellizzazione di problemi di transizione di fase. Dal punto di vista matematico tali equazioni sono caratterizzate da una dinamica doppiamente nonlineare che tipicamente non ne assicura la buona positura. In particolare, l’unicità delle soluzioni viene a mancare. Questo motiva l’introduzione e l'analisi di opportune formulazioni stocastiche per tali modelli, nell’ottica di ottenere effetti di regolarizzazione per rumore. Nella seconda parte il problema di regolarizzazione per rumore verrà inquadrato nel contesto più generale di equazioni di evoluzione stocastiche con drift singolare e verranno presentati alcuni risultati di unicità. L'applicabilità di tali tecniche identificherà naturalmente un concetto di criticità che porrà le equazioni doppiamente nonlineari in un regime supercritico. Per queste verrà fornito infine un risultato parziale di stabilità per rumore. I risultati presentati nei seminari sono stati ottenuti in collaborazione con F. Bertacco (Imperial College London) e U. Stefanelli (Università di Vienna). %%%%%%%%%%%%%%%%%%%%%%%%%%%%

[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!
