Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/ <http://www.umi-prisma.polito.it/>) Ricordiamo che oggi, giovedì 7 marzo 2024, Luca Avena (Università di Firenze) e Matteo Quattropani (Sapienza Università di Roma) parleranno di Incontri tra passeggiate aleatorie e dinamiche di opinione su grafi random 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://uniroma1.zoom.us/j/82939128330 <https://uniroma1.zoom.us/j/82939128330> Meeting ID: 829 3912 8330 Vi aspettiamo numerosi, Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Luca Avena (Università di Firenze) e Matteo Quattropani (Sapienza Università di Roma) TITOLO: Incontri tra passeggiate aleatorie e dinamiche di opinione su grafi random RIASSUNTO: Nella prima parte del seminario discuteremo risultati, classici o più recenti, della teoria che lega il comportamento di passeggiate aleatorie su grafi finiti a quello dei processi di coalescenza, e le relative implicazioni nell’analisi del tempo di consenso per dinamiche di opinione markoviane. Nella seconda parte del seminario presenteremo uno specifico risultato, ottenuto recentemente in collaborazione con Federico Capannoli e Rajat Shubra Hazra (Leiden University), in cui il grafo sottostante è aleatorio, orientato, e con un arbitraria sequenza di gradi. In particolare, in funzione della sequenza dei gradi scelta, identificheremo esplicitamente la legge dei tempi di incontro di due passeggiate aleatorie e, di conseguenza, il tempo di consenso per la dinamica di opinione associata. Discuteremo quindi delle implicazioni di questo risultato nel contesto applicativo del design delle reti, individuando le caratteristiche del grafo che tendono ad aumentare o a diminuire il tempo necessario a raggiungere il consenso. %%%%%%%%%%%%%%%%%%%%%%%%%%%% 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://www.youtube.com/@umi1922/videos %%%%%%%%%%%%%%%%%%%%%%%%%%%%

Seminario Andrea Di Primio - Politecnico di Milano - 6 Marzo 2024
by Luca Scarpa 05 Mar '24

05 Mar '24

Si segnala il seguente seminario a tutti gli interessati. Mercoledì 6 Marzo 2024, ore 11:30. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Andrea Di Primio. Title: Stochastic diffuse interface models with conservative noise. Abstract: Cahn-Hilliard type models are widely used to model phase separation phenomena occurring in multicomponent systems subject to thermodynamical stress. In 1970, a stochastic variant taking into account thermal effects driving spinodal decomposition was proposed by H. Cook. This model generalizes its deterministic counterpart and better fits available experimental data, especially in the early stages of phase separation. In this talk, I will examine the stochastic analysis of an almost-surely mass-conserving stochastic Cahn-Hilliard model, which stems from the original Cahn-Hilliard-Cook model when endowed with a conservative noise in divergence form. The mass conservation property is indeed expected in the deterministic version of the system. Our first-step investigation concerns the existence of unique probabilistically strong solutions to the equation, appealing to stochastic variational techniques. Some insights on the corresponding Allen-Cahn relaxation, for which we show conditional results, will also be given. In all models, a thermodynamical singular potential is considered. Further open questions will also be presented.

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 8 Marzo 2024, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: Jaromir Sant (University of Oxford UK) Title: *Inferring natural selection and allele age from allele frequency time series data via exact simulation* Abstract: A standard problem in population genetics is that of inferring evolutionary and biological parameters such as the strength of natural selection and allele age from DNA samples. Up until recently, most of the datasets available for such a task were obtained by sampling individuals from a contemporaneous population simultaneously, thereby offering a static snapshot of the population’s genetic diversity. However, recent advances in DNA extraction and sequencing technologies have allowed for ancient DNA found at archaeological sites to be analysed, leading to the creation of several time-series datasets detailing historical changes in allele frequencies. These datasets have paved the way for the development of powerful inferential techniques which explicitly exploit this new temporal dependence in the data to provide better estimators. In this talk I shall introduce a Markov Chain Monte Carlo framework which allows for inferring selection and allele age based on time-series data coming from an underlying Wright-Fisher diffusion. The chief novelty is that by augmenting the state space with the unobserved diffusion trajectory we are able to develop an efficient method in which trajectory updates and accept/reject probabilities can be calculated without error, in spite of the diffusion’s intractable transition density. We illustrate the method’s performance on simulated data, and subsequently apply it to an ancient DNA horse dataset. This is joint work with Paul Jenkins (Warwick), Jere Koskela (Newcastle), and Dario Spanò (Warwick). ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/87097731960?pwd=TjZ3YlNEbjFYeW9sUkl6OXN2SDB1QT09> Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

IEEE MetroLivEnv 2024 - Special Session PROBABILITY AND MATHEMATICAL STATISTICS FOR LIVING ENVIRONMENT AND METROLOGY
by Antonella Iuliano 03 Mar '24

03 Mar '24

Dear Colleagues, we would like to draw your attention to the upcoming 2024 IEEE INTERNATIONAL WORKSHOP ON METROLOGY FOR LIVING ENVIRONMENT that will be held at Chania, Crete, GREECE, June 12-14, 2024. The following Special Session is open to receive your submissions. PROBABILITY AND MATHEMATICAL STATISTICS FOR LIVING ENVIRONMENT AND METROLOGY Probability Theory and Statistics provide powerful tools for the development of new mathematical models to describe real life phenomena. In particular, the use of metrology refers to living environment plays an important role in many applicative fields to understand and identify sources of variability and to minimise their influence. The aim of this section is to cover the lack of probabilistic and machine learning approaches in this area. In fact, one of the most significant advantages using probabilistic models is to gain a comprehensive view of the uncertainty associated with a measurement result. A special attention will be give to results related to the quality of the living environment as a direct impact on human health and well-being. Website: https://www.metrolivenv.org/special-session-2 The deadline for Extended Abstract Submissions is March 10, 2024. https://www.metrolivenv.org/call-for-papers For further information and updates please visit the conference website: https://www.metrolivenv.org/index.php/ We are looking forward to Welcome you in Chania! Do not hesitate to forward this message to anyone who could be interested. Thank you very much for your kind consideration, and apologies for multiple copies. We look forward to hearing from you.

International Conference in Venice - CALL FOR PAPERS
by Monica Billio 02 Mar '24

02 Mar '24

23nd INTERNATIONAL CONFERENCE CREDIT 2024 *The frontiers of new risks: AI, digital and sustainability transitions * Venice, Italy 3 –4 October 2024 * * *GRETA Associati* (Venice, Italy),*CRIF* (Bologna, Italy), *European Datawarehouse *(Frankfurt am Main, Germany), *European Investment Fund* (Luxembourg), *Intesa Sanpaolo* (Milan, Italy) and *Modefinance* (Trieste, Italy) are partners in organising a Conference to be held in Venice on October 3-4, 2024. * * The CREDIT 2024 conference will bring together academics, practitioners and PhD students working in various areas of financial and socio-economic risk with the aim of creating a unique opportunity for participants to discuss research progress and policy as well as industry-relevant insights and directions for future research. CREDIT 2024 is the *twenty-thrid* in a series of events dedicated to various aspects of credit risk and organised under the auspices of: the *Department of Economics *and*VERA - Venice centre in Economic and Risk Analytics for public policies* - of the *Ca’ Foscari University of Venice*,*Joint Research Center European Commission*, *ABI - Italian Banking Association*, *AIAF - Associazione Italiana per l'Analisi Finanziaria*, *AIFIRM - Associazione Italiana Financial Industry Risk Managers*. Sustainability necessarily involves the adaptation of today’s business model to the dynamic nature of the current digitalised environments. Corporations need to make sure that resources, especially technology, are being used responsibly and efficiently to improve the lives of the present generations and future generations as well as strengthen their relationships with the environment as to solve sustainability-related problems such as poverty, environmental degradation, pollution and inequality. Artificial Intelligence (AI) has the potential to address these societal problems including sustainability. The climate crisis and the degradation of the physical environment are complex problems that require the most innovative and advanced solutions. The real value of AI hence lies in its ability to facilitate and foster environmental and social governance, rather just as a tool to reduce pollution, poverty and resource depletion. In the age of AI, societies depend on big data, social media, knowledge management and data science to survive and achieve these sustainability goals. AI has the potential to reshape not only finance and industry but also the whole society. There is need to understand opportunities and challenges as to properly manage all relevant risks. The organisers encourage submissions on any topic within the overall theme of the conference, with attention to *the use of AI to assess the sustainability impact of finance *(i.e. exploiting AI techniques or Big Data to bridge primary information gaps and proxy the sustainability impact) and *on how climate and digital risks may interact* (i.e. climate denial, social media and social media strategies including deepfakes). The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Patrick Bolton *(Imperial College London), and *Roberto Rigobon* (MIT Sloan School of Management). The Conference will also include panel discussions on the major issues at stake with the views of researchers', practitioners' and policy makers. The SCIENTIFIC COMMITTEE for the Conference consists of: *Marcin Kacperczyk *(Imperial College London, Programme Chair) *Monica Billio* (Ca’ Foscari University of Venice & GRETA) *Marie Brière* (AMUNDI & Université Libre de Bruxelles) *Lucia Alessi* (Joint Research Center, European Commission) *Leonardo Gambacorta *(Bank For International Settlements) *Mila Getmansky* (Isenberg School of Management, UMass Amherst) *Christian Gollier* (Toulouse School of Economics) *Helmut Kraemer-Eis *(European Investment Fund) *Jan Pieter Krahnen *(Leibniz Institute for Financial Research SAFE & Goethe University) *Steven Ongena* (University of Zurich, Swiss Finance Institute, KU Leuven, NTNU Business School & CEPR) *Roberto Rigobon *(MIT Sloan School of Management) *Stephen Schaefer* (London Business School) *Marti Subrahmanyam *(NYU Stern Business School) CALL FOR PAPERS Those wishing to present a paper at the Conference should submit by *May 31, 2023 *to the address given below (preferably in electronic format). Please indicate to whom correspondence should be addressed. Decisions regarding acceptance will be made by *June 30, 2023*. The final version of accepted papers must be received by August 31, 2023.
