SEMINAR: Gregor Kastner @Luiss - 15 Apr
by Matteo Iacopini 09 Apr '26

09 Apr '26

Dear all, On Wednesday, 15th April, at 12:00 in room A307b, the Department of AI, Data and Decision Sciences of Luiss University of Rome will host a seminar by Gregor Kastner (University of Klagenfurt) Title: "Bayesian nonparametric priors for model-based (partial) clustering” Abstract: We discuss variations of prior distributions for finite and potentially infinite mixture models. First, we extend standard Bayesian nonparametric spatial priors to additionally incorporate the temporal dimension, thereby allowing for spatio-temporal clustering. Second, we show how these priors can be modified to cater for partial effects by a priori distinguishing between control and target variables. Third, we propose a novel prior for modelling the weights in mixture models. It is based on the Selberg Dirichlet distribution, an extension of the standard Dirichlet with a repulsive term, and penalises mixture weights that lie close to each other. The approaches are illustrated with applications from various fields: modelling unemployment, quantifying the effect of European agricultural subsidies, and uncovering patterns in biomedical data. Anyone interested in attending is welcome; just email me for logistical purposes. Hoping to meet you there!

Seminario Bignamini - 14 Aprile - Università di Milano-Bicocca
by Federica Masiero 07 Apr '26

07 Apr '26

Buongiorno segnalo il seguente seminario *Martedì 14 Aprile alle ore 11 * in *aula U3/5* (Edificio U3 • BIOS • Università degli Studi di Milano-Bicocca <https://www.google.com/maps/place/Edificio+U3+%E2%80%A2+BIOS+%E2%80%A2+Univ…>), Piazza della Scienza 2, Milano *Speaker*: Davide Augusto Bignamini (Università degli studi dell'Insubria.) *Titolo: *Pathwise uniqueness for stochastic PDEs with singular locally Hölder-continuous drift *Abstract: *This talk is based on the paper [1]. The main focus is pathwise uniqueness for mild solutions to stochastic PDEs with a Hölder-continuous perturbation in the drift, given in differential form. The singularity of the drift perturbation allows to achieve novel pathwise uniqueness results for several classes of examples, ranging from fluid-dynamics to phase-separation models, previously studied only in the context of weak uniqueness, see [2,3].

Seminars in Statistics at Collegio Carlo Alberto - Pierre LATOUCHE (Université Clermont Auvergne)

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Venerdì 10/04/2026, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ 12.00-13.00 Speaker: Pierre LATOUCHE (Université Clermont Auvergne) Title: Importance weighted variational graph autoencoders for inference in deep latent position block models Abstract: In this presentation, I will first show how latent position models can be made compatible with block models for network analysis through the use of deep generative models. I will focus on the binary edge case and introduce a new random graph model along with a variational graph auto encoding strategy for inference. I will discuss the identifiability of the model and explain how model selection can be performed. I will then move to the sparse discrete edge case in the same deep, block compatible, modelling framework. I will show how importance weighted variational inference can strongly improve the inference procedure over the classical variational auto encoding strategy. I will give the importance weights used for sampling and show that, in the limit, the lower bound obtained converges to the integrated log likelihood of the data. Through this presentation, I will emphasise the need to rely on flexible random graph models to obtain relevant loss functions. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare un’email a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it> Il webinar è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.

Prof. Fabrizio Lillo's seminar at University of Milano-Bicocca.
by Giorgio Rizzini 03 Apr '26

03 Apr '26

Dear all, we are pleased to announce the following seminar by Prof. Fabrizio Lillo (Scuola Normale Superiore) on *Tuesday, April 14th, 2026,* starting at 11:00 at the U7 building, room 4057, Department of Statistics and Quantitative Methods, University of Milano-Bicocca (Milan): *Why is the estimation of market impact of large trades with public market data so challenging?* *Abstract:* Estimating market impact and transaction costs of large trades (metaorders) is a very important topic in finance. However, using models of price and trade based on public market data provides average price trajectories which are qualitatively different from what is observed during real metaorder executions. We claim that this is a generic phenomenon due to the fact that even sophisticated statistical models are unable to correctly describe the origin of the autocorrelation of the order flow. In the talk (i) we propose a modified Transient Impact Model which provides more realistic trajectories by assuming that only a fraction of the metaorder trading triggers market order flow and (ii) we propose to use Bayesian online change-point detection methods to identify order flow regime shifts in real-time and enable online predictions of order flow and market impact. The seminar will be held in a hybrid format (in-person and online). If you would like to attend remotely or require any further information, please write to *giorgio.rizzini(a)unimib.it <giorgio.rizzini(a)unimib.it>* Best regards and happy Easter!
