**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Veberdi 2 Ottobre 2015 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Frederic LAVANCIER (Université de Nantes) DETERMINANTAL POINT PROCESS MODELS AND STATISTICAL INFERENCE Abstract: In this talk, I will demonstrate that Determinantal point processes (DPPs) provide useful models for the description of repulsive spatial point processes. Such data are usually modeled by Gibbs point processes, where the likelihood and moment expressions are intractable and simulations are time consuming. I will recall the definition of a DPP and review some of these appealing properties which make DPP models well suited for statistical analysis. In particular the ’most repulsive’ DPP will be characterized. Parametric models of DPPs will be introduced, where the likelihood and moment expressions can be easily evaluated and realizations can be quickly simulated. Some illustrations on real datasets will be presented. This work has been carried out in collaboration with Jesper Møller and Ege Rubak, Aalborg University. The study of the repulsiveness of DPPs is part of a joint work with Christophe Biscio, University of Nantes. Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto. Cordiali saluti, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it

Seminar announcement
by Marco Scarsini 23 Sep '15

23 Sep '15

Department of Economics and Finance Internal Seminar Thursday,September 24, from 1 to 2 pm Meeting room, 5th floor János Flesch (Maastricht University). Title: Subgame-Perfect Epsilon-Equilibrium in Perfect Information Games. Abstract: We consider multi-player perfect information games. These games are played on a tree of infinite depth, where each node is controlled by one of the players. Play of the game starts at the root. At every node that play visits, the player who controls this node has to choose one of the outgoing arcs. This induces an infinite sequence of nodes in the tree, and depending on this sequence, each player receives a payoff. A strategy profile is called a Nash epsilon-equilibrium if no player can gain more than epsilon by a unilateral deviation. Such games are known to admit a Nash epsilon-equilibrium (Mertens and Neyman 1986) for all positive epsilon, provided that the payoff functions of the players are bounded and Borel measurable. In this talk, we examine the existence of a subgame-perfect epsilon-equilibrium in these games. A subgame-perfect epsilon-equilibrium is a strategy profile that induces a Nash epsilon-equilibrum in every subgame (that is, not only from the root, but also from every other node in the tree). We provide an overview of recent existence and non-existence results. Particular attention is paid to the result (Flesch and Predtetchinski 2015) that a subgame-perfect epsilon-equilibrium exists, for every epsilon>0, if the payoff functions are bounded and exhibit common preferences at the limit. Moreover, if the payoff functions also have finite range, then there exists a pure subgame-perfect 0-equilibrium. These results extend and unify the existence theorems for bounded and semicontinuous payoffs in Flesch et al [2010] and Purves and Sudderth [2011]. ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza LUISS Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/

Saleri" VI piano - Dipartimento di Matematica, Politecnico di Milano, nell'ambito delle iniziative MOX, si svolgerà il seguente seminario: Relatore: Alois Kneip Universitat Bonn Titolo: Nonparametric Registration to Low-Dimensional Functionspaces Abstract: Registration aims to decompose amplitude and phase variation of samples of curves. Phase variation is captured by warping functions which monotonically transform the domains of sample curves. Resulting registered curves should then only exhibit amplitude variation. Most existing registration method rely on aligning typical shape features like peaks or valleys to be found in each sample function. It is shown that this is not necessarily an optimal strategy for subsequent statistical data exploration and inference. In this context a major goal is to identify low dimensional linear subspaces of functions that are able to provide accurate approximations of the observed functional data. In this paper we present a registration method where warping functions are defined in such a way that the resulting registered curves span a low dimensional linear function space. Problems of identifiability are discussed in detail, and connections to established registration procedures are analyzed. The method is applied to real and simulated data. Tutti gli interessati sono invitati a partecipare.

Seminario MASSIMINI (RGS, ADAMSS, CIMAB & Matematica Applicata)
by Giacomo Aletti (giacomo.aletti) 15 Sep '15

15 Sep '15

Con preghiera di diffusione tra tutti i possibili interessati, scusandomi per invii multipli. Cordialmente, Giacomo Aletti -------------- Nell'ambito dei Reading Group Seminars e del Seminario di Matematica Applicata, in collaborazione col centro ADAMSS e il CIMAB, il giorno lunedì 21 Settembre 2015, alle ore 14.30, nell'Aula Dottorato (primo piano) del Dipartimento di Matematica dell'Universita' degli Studi di Milano, Via C. Saldini, 50, Milano, "Consciousness and complexity: from theory to practice" Marcello MASSIMINI Dipartimento di Scienze biomediche e cliniche 'Luigi Sacco' Università degli Studi di Milano Abstract: We usually assess another individual’s level of consciousness based on her/his ability to connect to the surrounding environment and produce appropriate responses. However, conscious experience can be entirely generated within the brain, even in the absence of any interaction with the external world; this happens almost every night, during dreaming, and may occur during certain forms of anesthesia as well as in brain-injured patients who emerge from coma and remain unresponsive. Hence, clinical and physiological evidence advocate the development of brain-based metrics that are independent on both sensory inputs and motor outputs. As an attempt in this direction, an empirical measure of brain complexity has been recently developed based on the electroencephalographic (EEG) response to a direct cortical perturbation with transcranial magnetic stimulation (TMS), the perturbational complexity index (PCI). Based on theoretical postulates, PCI gauges the conjoint presence of integration and information in the human brain, independently of sensory inputs and motor outputs. In a series of experiments, PCI was tested on TMS-evoked potentials recorded in healthy subjects during wakefulness, dreaming, NREM sleep, and different levels of sedation induced by different anesthetic agents (including the dissociative anesthetic ketamine), as well as in patients who emerged from coma and attained a stable diagnosis. Overall, PCI allows a reliable assessment of the level of consciousness at the individual level even in subjects who are fully disconnected from the surrounding environment on both the input and output side. These measurements are scientifically relevant in the context of the information integration theory of consciousness (IITC) and prompt further validation toward the development of a practical diagnostic test. ================= Reading Group Seminars: The Reading Group Seminars (RGS) are organized within an open community of researchers interested in applying up to date mathematical modeling and data analysis approaches to the study of biological systems. The RGS take place at the Math. Department in Milan (via Saldini).
