Title: *Regression analysis with density functions in Bayes spaces*
*Ivana Pavlů*, Palacký University Olomouc, Czech Republic
*Abstract*:
Regression analysis offers tools for explaining the relation between (a set
of) dependent and independent variables. Recent advances extend the
available response types from uni- or multivariate to functional, and more
recently also distributional responses. For functional distributions, often
represented through probability density functions, the Bayes space
framework was developed to respect the relative information they carry. The
Hilbert space structure of Bayes space enables one to utilize standard
methods of functional data analysis for the use on - properly transformed -
density functions. Focusing on regression analysis, it is possible to
construct adequate models with densities on the side of both the dependent
and independent variables.
In this seminar, a brief overview of regression models for univariate
densities will be presented. A closer attention will be given to the
possible generalization of additive regression model for bivariate
distributions. Finally, an outlook at the Bayesian inference in linear
regression with probability densities will be discussed. All proposed
methods will be demonstrated on real data from the fields of geochemistry
and demographics.

Title: Spectral complexity of deep neural networks
Date: Monday, May 29, 2024 at 11.30
Place: Aula 704 (7th floor) , Dipartimento di Matematica at University of Genova, Via Dodencaneso 35,
Abstract: It is well-known that randomly initialized, push-forward,
fully-connected neural networks weakly converge to isotropic Gaussian
processes, in the limit where the width of all layers goes to infinity.
In this paper, we propose to use the angular power spectrum of the
limiting fields to characterize the complexity of the network
architecture. In particular, we define sequences of random variables
associated with the angular power spectrum, and provide a full
characterization of the network complexity in terms of the asymptotic
distribution of these sequences as the depth diverges. On this basis, we
classify neural networks as low-disorder, sparse, or high-disorder; we
show how this classification highlights a number of distinct features
for standard activation functions, and in particular, sparsity
properties of ReLU networks. Our theoretical results are also validated
by numerical simulations.

Title: Bayesian network structural learning from complex survey data
Statistical Network Science Seminar Series- Bernoulli Society
Speaker: Paola Vicard (Department of Economics, Università Roma Tre, Rome, Italy)
Abstract: The association structure of a Bayesian network can be known in advance by subject matter knowledge or have to be learned from a database. One of the most widely used procedures is the PC algorithm consisting in carrying out several independence tests on the available data set and in building a Bayesian network according to the tests results. In case of data driven learning, the PC algorithm is based on the irremissible assumption that data are independent and identically distributed. Unfortunately, official statistics data are generally collected through complex sampling designs, then the aforementioned assumption is not met. In such a context the PC algorithm fails in learning the structure. To avoid this, the sample selection must be taken into account in the structural learning process. A modified version of the PC algorithm is proposed for inferring causal structure from complex survey data. It is based on resampling techniques for finite populations. A simulation experiment showing the robustness with respect to departures from the assumptions and the good performance of the proposed algorithm is carried out.

*Abstract*
Per il tema "Dati e Previsioni" si propone l'impostazione didattica basata
sui problemi. In particolare, si propone di utilizzare, in maniera
appropriata e con la finalità di sollecitare le abilità comunicative ed
argomentative, alcuni problemi e paradossi della probabilità condizionata
che nel corso del tempo sono stati occasione di discussioni vivaci e
intriganti. I problemi selezionati e sperimentati nel corso degli ultimi
anni in classi della scuola secondaria, nei quali l'enfasi è posta
soprattutto sul significato dei simboli e delle formule, forniscono anche
un modo per stimolare gli obiettivi di "processo" (argomentare e
dimostrare, comunicare, rappresentare, collegare) spesso trascurati a
favore dei soli obiettivi di "contenuto". Una tale modalità operativa può
essere d'aiuto sia agli insegnanti per mitigare le difficoltà che loro
stessi soventemente riscontrano nella concettualizzazione (ovvero quella
discontinuità tra i processi cognitivi degli studenti e l'astrazione) e sia
agli stessi studenti per meglio orientarsi quando le circostanze della vita
quotidiana sicuramente lo richiederanno.
Gli interessati sono cordialmente invitati a partecipare,

Dear all,
the last OWABC www.warwick.ac.uk/oneworldabc<http://www.warwick.ac.uk/oneworldabc> seminar of Season 5 is quickly approaching.
We are glad to announce that our next speaker is Mark Beaumont (University of Bristol), who will talk about "Model misspecification in population genomic" on Thursday the 30th May at 9am UK time.
Abstract: In likelihood-free settings, problematic effects of model misspecification can manifest themselves during computation, leading to nonsensical answers, particularly causing convergence problems in sequential algorithms. This issue has been well studied in the last 10 years, leading to a number of methods for robust inference. In practical applications, likelihood-free methods tend to be applied to the output of complex simulations where there is a choice of summary statistics that can be computed. One approach to handling misspecification is to simply not use summary statistics computed from simulations of the model under the prior that cannot be matched with those observed in the data. This presentation gives a brief review of methods for observing and handling misspecification in ABC and SBI, and then discusses approaches that we have explored in a population genomic modelling framework.
The talk will be streamed on MS Teams, at the link
