Seminar: Andrea Capozzo March 19, 2024, Ca' Foscari University of Venice
by Carlo Gaetan 09 Mar '24

09 Mar '24

Dear all, we are glad to announce the following hybrid seminar *March 19, 2024, 12:15 PM* *Where*: Aula Delta 2C- edificio Zeta (Campus Scientifico), Via Torino, 155 Mestre (Venice, Italy) Zoom: https://unive.zoom.us/j/85153268624?pwd=MzBhdlA2M1B2dThJQ2Y5T0EwUE5PZz09 *Speaker*: Andrea Cappozzo, Università degli Studi di Milano (Milano, Italy) *Title*: Penalized mixed-effects multitask learning: a framework for regularizing multilevel models with applications on DNA methylation biomarkers creation *Abstract:* Linear mixed modeling is a well-established technique widely employed when observations possess a grouping structure. Nevertheless, this standard methodology is no longer applicable when the learning framework encompasses a multivariate response and high-dimensional predictors. To overcome these issues, a penalized estimation scheme based on an expectation-maximization (EM) algorithm is proposed, in which any penalty criteria previously devised for fixed-effects models can be conveniently incorporated into the fitting process. We employ the novel methodology for creating surrogate biomarkers of cardiovascular risk factors, such as lipids and blood pressure, from whole-genome DNA methylation data in a multi-center study. The proposed approach shows promising results in both predictive accuracy and bio-molecular interpretation compared to state-of-the-art alternatives.

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.

Seminar in Statistics - JAROMIR SANT

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/>
