No Free Lunch Seminar by Dr. Joao da Gama Batista, Fri April 10 1:00 PM Aula Bianchi @ SNS
by Giacomo Bormetti 31 Mar '15

31 Mar '15

Fri April 10 2015, 1:00 PM in Aula Bianchi, Scuola Normale Superiore Pisa Joao da Gama Batista Laboratoire de mathématiques appliquées aux systèmes École Centrale de Paris will deliver the seminar "Sudden trust collapse in networked societies" Abstract: Trust is a collective, self-fulfilling phenomenon that suggests analogies with phase transitions. We introduce a stylized model for the build-up and collapse of trust in networks, which generically displays a first order transition. The basic assumption of our model is that whereas trustworthiness begets trustworthiness, panic also begets panic, in the sense that a small decrease in trustworthiness may be amplified and ultimately lead to a sudden and catastrophic drop of collective trust. We show, using both numerical simulations and mean-field analytic arguments, that there are extended regions of the parameter space where two equilibrium states coexist: a well-connected network where global confidence is high, and a poorly connected network where global confidence is low. In these coexistence regions, spontaneous jumps from the well-connected state to the poorly connected state can occur, corresponding to a sudden collapse of trust that is not caused by any major external catastrophe. In large systems, spontaneous crises are replaced by history dependence: whether the system is found in one state or in the other essentially depends on initial conditions. All interested people are kindly invited.

Seminario di Bernardo Nipoti a Pavia
by Carbone Raffaella 26 Mar '15

26 Mar '15

Cari colleghi, vi annuncio che martedì 31 marzo, alle ore 14 precise, nell'aula Beltrami del Dipartimento di Matematica dell'Universita' di Pavia, Bernardo Nipoti (Dipartimento di Economia e Statistica - Università di Torino) terrà un seminario dal titolo Rediscovery of Good-Turing estimators via Bayesian Nonparametrics Sunto: The problem of estimating discovery probabilities originated in the context of statistical ecology, and in recent years it has become popular due to its frequent appearance in challenging applications arising from biology, bioinformatics, genetics, linguistics, etc. A full range of statistical approaches, parametric and nonparametric as well as frequentist and Bayesian, have been proposed for estimating discovery probabilities. We investigate the relationship between the celebrated Good-Turing approach, which is a frequentist nonparametric approach developed in the 1940s, and the Bayesian nonparametric approach recently introduced in the literature. Specifically, under the assumption of a two parameter Poisson-Dirichlet prior, we show that Bayesian nonparametric estimators of discovery probabilities are asymptotically equivalent to suitably smoothed Good-Turing estimators. As a by-product of this result, we present and discuss a methodology for deriving asymptotic credible intervals to be associated to the Bayesian nonparametric estimators of discovery probabilities.

26 Mar '15

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Lunedì 30 marzo ore 14 - Aula Belpasso - Dipartimento di Matematica Università di Roma Tor Vergata Speaker: Pierpaolo Brutti, Università "La Sapienza" - Roma Title: Estimating the Intrinsic Dimension: The Bayesian way Abstract: In this talk I will first review some of the methods proposed for making inference on the intrinsic dimension of point cloud data sampled from a low-dimensional structure embedded in a high–dimensional ambient space, and then I will describe a Bayesian solution based on a composite likelihood built under working independence assumptions suggested by MacKay and Ghahramani. In order to get a posterior with approximately correct asymptotic behavior and curvature, I will consider some options to calibrate this pseudolikelihood and then compare in simulated and real examples a standard MCMC method against a variation of the default Bayesian framework of Ventura et al. (2013) (joint work with Alessandro Lanteri). Cordiali saluti Claudio Durastanti

seminario all'IMATI-Milano
by Antonella Bodini 26 Mar '15

26 Mar '15

Mercoledi' 1 aprile alle ore 14 presso la sede di Milano dell'IMATI, via Bassini 15, Sala Pentagonale al secondo piano, Valérie Bélanger dell'Universita' HEC Montréal terra' un seminario dal titolo Analysis and development of real-time ambulance fleet management strategies di cui segue il sunto. Tutti gli interessati sono invitati a partecipare. ____________________________ Sunto: Emergency medical services (EMS) evolve in highly random and dynamic contexts. Indeed, the arrival of emergency calls is uncertain and varies throughout the day, forcing decision makers to adapt their decisions in response to observed changes. Two types of decisions are generally considered in real-time: dispatching and relocation. Dispatching decisions consider the selection of which ambulance to send to an emergency call. Relocation decisions consist in relocating available ambulances throughout the day in response to changes in the system state. Given the situation faced by EMS, the analysis and development of real-time management strategies to ensure a good service to the population is clearly of interest. In a first study, several ambulance relocation strategies are compared, and extensive simulation experiments are reported allowing to analyze the performance of these strategies when they face different level of system workload. Results of this study confirm the relevance of simulation methods to support decision-making in EMS stochastic environment. More importantly, they provide researchers and decisions makers with valuable insights on the use of relocation strategies, including the tradeoff between service level and personnel well-being. In a subsequent study, an innovative real-time ambulance fleet management strategy is proposed. New mathematical models and solution approaches are then developed to deal with both relocation and pre-assignment decisions. Preliminary results show that considering explicitly pre-assignment decisions, which are directly related to dispatching decisions, impact location decisions and can help better predict system performances.

No Free Lunch Seminar by Dott. Tommaso Colozza, Wed April 1 1:00 PM Aula Mancini @ SNS
by Giacomo Bormetti 26 Mar '15

26 Mar '15

Wed April 1 2015, 1:00 PM in Aula Mancini, Scuola Normale Superiore Pisa Tommaso Colozza Dipartimento di Statistica e Matematica Applicata all'Economia - Università di Pisa will deliver the seminar "Supply of public debt and demand for risk premia: a Minskian approach to credit risk" Abstract: Financial stability of EMU countries is managed by policy makers through several key macroeconomic indicators; the market instead monitors creditworthiness with credit risk premia embedded in sovereign yields. A demand-supply approach solves this duality: in a Minskian framework, positive inelastic shifts in debt-to-GDP ratio due to widespread macro-financial distress may lower risk appetites of lenders and increase risk premia, up to default. Time-variating risk appetites justify statistical relevance of debt-to-gdp variation on yields levels; if conveniently decomposed, debt velocity allows also to imply a default probability measure comparable to standard CDS-implied measures. All interested people are kindly invited.

24 Mar '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, il giorno lunedì 19 Gennaio 2015, alle ore 14.30, nell'Aula C del Dipartimento di Matematica dell'Universita' degli Studi di Milano, Via C. Saldini, 50, Milano, "Testing spiking neural network cerebellar model in closed-loop: three neurorobotic paradigms" Alberto ANTONIETTI Neuroengineering and medical robotics lab., Politecnico di Milano, ABSTRACT: The cerebellum is involved in a large number of different neural processes, especially in associative learning and in fine motor control. To develop a comprehensive theory of sensorimotor learning and control, it is crucial to determine the neural basis of coding and plasticity embedded into the cerebellar neural circuit and how they are translated into behavioral outcomes in learning paradigms. Learning has to be inferred from the interaction of an embodied system with its real environment, and the same cerebellar principles derived from cell physiology have to be able to drive a variety of tasks of different nature, calling for complex timing and movement patterns. We have coupled a realistic cerebellar spiking neural network with a real robot and challenged it in multiple diverse sensorimotor tasks. Adaptive motor control protocols with acquisition and extinction phases have been designed and tested, including an associative Pavlovian task (Eye blinking classical conditioning), a vestibulo-ocular task and a perturbed arm reaching task operating in closed-loop. A bidirectional long-term plasticity rule implemented at parallel fibers-Purkinje cell synapses modulated the output activity in the deep cerebellar nuclei. In all tasks, the neurorobot learned to adjust timing and gain of the motor responses by tuning its output discharge. It succeeded in reproducing how human biological systems acquire, extinguish and express knowledge of a noisy and changing world. ================= 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).

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Mercoledi` 25 marzo ore 14 - 16 Aula D'Antoni 1101 Dipartimento di Matematica Università di Roma Tor Vergata Speakers: Armin Schwartzman & Dang Cheng Department of Statistics, North Carolina State University Title: Distribution of the Height of Local Maxima of Gaussian Random Fields Abstract: Let {f(t): t \in T} be a smooth Gaussian random field over a parameter space T, where T may be a subset of Euclidean space or, more generally, a Riemannian manifold. We provide a general formula for the distribution of the height of a local maximum P { f(t_0)>u | t_0 is a local maximum of f(t) } when f is non-stationary. Moreover, we establish asymptotic approximations for the overshoot distribution of a local maximum P { f(t_0)>u+v | t_0 is a local maximum of f(t) and f(t_0)>v } as v \to \infty. Assuming further that f is isotropic, we apply techniques from random matrices theory related to the Gaussian orthogonal ensemble to compute such conditional probabilities explicitly when T is Euclidean or a sphere of arbitrary dimension. Such calculations are motivated by the statistical problem of detecting peaks in the presence of smooth Gaussian noise.

Seminario Elena Kosygina
by Mariani, Mauro 17 Mar '15

17 Mar '15

Il giorno Mercoledi' 25 marzo 2015, alle ore 14:00, nell'Aula G del Dipartimento di Matematica dell'Universita' la Sapienza di Roma Elena Kosygina (Baruch College and the CUNY Graduate Center) effettuera' un seminario di circa un'ora: TITOLO: Excited random walks in Markovian cookie environments on Z SUNTO: We consider a nearest-neighbor random walk on Z whose probability ω(x, n) to jump to the right from site x depends not only on x but also on the number of prior visits n to x. The collection (ω(x, n)) is sometimes called the “cookie environment” due to the following informal interpretation. Upon each visit to a site the walker eats a cookie from the cookie stack at that site and chooses the probability to jump to the right according to the “flavour” of the cookie eaten. Assume that the cookie stacks are i.i.d. and that only the first M cookies in each stack may have “flavour”.

Master of Science (MSc) Scholarship in Statistics
by elisa＠mi.imati.cnr.it 16 Mar '15

16 Mar '15

Alla cortese attenzione dei possibili interessati. *Master of Science (MSc) Scholarship * *Project:* Developing Inversion Methods for Non-stationary Thinning of Point Processes An MSc scholarship is available to support a student for full-time study towards a research Master's degree in the project specified above in the Department of Mathematics and Statistics at the University of Otago in Dunedin. Details are as follows: *Award offered: University of Otago Master program -- MARSDEN FUNDED* *Length of Tenure: 12 months or until thesis is submitted (whichever is earlier)* *Emolument per annum: NZ$16,000 plus domestic tuition fee waiver** *Additional funding is available for travel* *Start date: The earliest start date is May 2015 (can be negotiated)* *Part-time study: Part-time study is not permitted* ** *For international applicants who need to pay international tuition fees, the scholarship contributes a fee maximum of domestic tuition and the successful candidate needs to meet the remainder of the international tuition fees http://www.otago.ac.nz/international/otago002190.html** This scholarship is funded by a Royal Society of New Zealand Marsden Fast-start grant awarded to Dr Ting Wang (Department of Mathematics and Statistics, University of Otago). The regulations governing the award are the same as those for University of Otago Scholarships: http://www.otago.ac.nz/study/scholarships/otago013798.pdf This project aims to develop analytical and numerical methods to inverse point processes with non-stationary missing probabilities, where the probability of missing an event depends on time and event size. The successful applicant will learn point process theory; carry out part of the simulation study and some data analysis using the statistical software R under the supervision of Dr Ting Wang. As the Associate Investigators (AIs) Associate Professor Jiancang Zhuang (Institute of Statistical Mathematics, Tokyo) and Dr Koji Kiyosugi (University of Tokyo) are both based in Japan, a visit to Japan is likely to be funded by this project for the student to receive informal mentoring from the AIs. *Eligibility* Applicants should hold a BSc (Hons) or equivalent four year degree in Statistics or a related discipline with a strong research interest. For an exceptional graduate student who has only completed a BSc degree without Honours year, additional scholarship may be awarded for the year of course studies. *Applying for this scholarship* Please contact Dr Ting Wang (twang(a)maths.otago.ac.nz <mailto:twang@maths.otago.ac.nz>, http://www.stats.otago.ac.nz/?People =ting_wang) and provide a covering letter explaining your interest in this project, a CV, a copy of your full academic transcript, and details of two academic referees.

Lunedì 30 marzo 2015 alle ore 14:30, nell'aula 3014 del Dipartimento di Matematica e Applicazioni dell'Università di Milano-Bicocca (edificio U5, via Cozzi 55, Milano), Alessandra Cipriani (WIAS Berlin) terrà un seminario dal titolo "Rates of convergence for extremes of geometric random variables and marked point processes" Trovate il sommario di seguito. Tutti gli interessati sono invitati a partecipare. Francesco Caravenna %%%%%%%%%%%%%%%%%% Abstract: We study the problem of extremes for univariate and bivariate geometric laws. We determine the rate of convergence of the maximum of \iid geometric random variables and bivariate vectors following the Marshall-Olkin geometric distribution to a Gumbel distribution, and propose a new discretised version as limit. We introduce marked point processes of exceedances (MPPE's) whose \iid marks are bivariate Marshall-Olkin geometric variables. We use the Stein-Chen method for Poisson process approximation to determine bounds on the error of the approximation of the law of the MPPE by that of a Poisson process.

*Venerdi' 20 Marzo 2015*, *ore 14:00* Consiglio Nazionale delle Ricerche, Istituto per le Applicazioni del Calcolo "Mauro Picone", Via dei Taurini 19, 00185 Roma Aula Riunioni (VI piano) *ALESSANDRO DE GREGORIO * (Universita' di Roma "Sapienza") terra' un seminario dal titolo *Isotropic transport processes: a survey of results* ABSTRACT: The motion of a particle whose velocity undergoes jumps of random size at random times constitutes the prototype of a transport process (also called random flight or random evolution). In this talk the probabilistic construction of the isotropic transport processes is outlined. In particular, we assume that the joint probability distribution of the lengths of the displacements is a Dirichlet law. Several results in this context are discussed. We also introduce reflecting transport processes by means of a geometric approach. These processes are often applied in statistical physics and biology. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Giovanni Luca Torrisi.

No Free Lunch Seminar by Prof. Roberto Renò, Friday March 20 1:00 PM Aula Bianchi @ SNS
by Giacomo Bormetti 11 Mar '15

11 Mar '15

Friday March 20 2015, 1:00 PM in Aula Bianchi, Scuola Normale Superiore Pisa Roberto Renò Dipartimento di Economia Politica e Statistica, Università di Siena will deliver the seminar “Multi-jumps” Abstract: The simultaneous occurrence of jumps in several stocks (multi-jumps) can be associated to major nancial news, is correlated with sudden spikes of the variance risk premium, and determines an increase in the stock variances and correlations which signicantly deteriorates the diversication potential of asset allocation. The latter evidence implies a reduction in the demand of stocks by an aware risk-averse investor. These facts can be easily overlooked by the usage of standard univariate jump statistics, which just lack su cient power. They are instead revealed in a clearly cut way by using a novel test based on smoothed estimators of the integrated variance of individual stocks. Joint work with Massimiliano Caporin and Aleksey Kolokolov. All interested people are kindly invited.

de Finetti risk seminar - march 2015
by Emanuela Rosazza 10 Mar '15

10 Mar '15

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Monetary Utility Functions with the CxLS (convex level sets) property Freddy Delbaen ETH Zurich, Switzerland ABSTRACT Monetary utility functions are -- except for the expected value -- not of von Neumann-Morgenstern type. In case the utility function has convex level sets in the set of probability measures on the real line, we can give some characterisation that comes close to the vN-M form. For coherent utility functions this was solved by Ziegel. The general concave case under the extra assumptions of weak compactness, was solved by Stephan Weber. In the general case the utility functions are only semi continuous. Using the fact that law determined utility functions are monotone with respect to convex ordering, we can overcome most of the technical problems. The characterisation is similar to Weber's theorem except that we need vN_M utility functions that take the value $-\infty$. Having convex level sets can be seen as a weakened form of the independence axiom in the vN-M theorem. This is joint work with Bellini, Bignozzi and Ziegel. LOCATION: The seminar will be held on Wednesday, March 18, at 18.00, Aula di rappresentanza, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano. A refreshment will be offered at 17.30. Scientific Committee: Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ. Bocconi) Prof. Massimo Marinacci (Univ.

To improve power, a number of studies have investigated the benefits of utilizing available genomic and biological information, however, the relative merits of different methods remain unclear. We focus on the stratified FDR control (Sun et al., 2006, Genetic Epidemiology 30:519-530) and weighted p-value method (Genovese et al., 2006, Biometrika 93:509-524). The two approaches model the prior info distinctively. Weighted p-value approach converts the available prior information to test-specific weighting factor and adjusts the p-values accordingly. In contrast, stratified FDR divides tests into several disjoint strata based on the prior information and applies the FDR control separately in each stratum. We formulate the two approaches in one framework and show the trade-off between power and robustness by theoretical, simulation, and application studies. Robustness is consequential in applications, safeguarding against potential uninformative or even misleading prior information. To demonstrate the practical relevance of these methods, I discuss two recent genome-wide association studies of Cystic Fibrosis modifier genes, in which over 500,000 genetic markers are investigated for association with lung functions in individuals with CF and the available prior is of quantitative nature (Wright et al. 2011, Nature Genetics 43:539-548), and for association with meconium ileus and the prior is of categorical nature (Sun et al. 2012, Nature Genetics 44:562-569). If time allows, I will briefly discuss additional interesting analytical challenges in these studies.

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Lunedi` 9 Marzo - ore 14.00 Aula D'Antoni 1101 Dipartimento di Matematica Università di Roma Tor Vergata Speaker: Elena Villa - Università degli Studi di Milano, Dipartimento di Matematica Title: MINKOWSKI CONTENT AND MEAN DENSITY OF RANDOM CLOSED SETS: some theoretical results and statistical applications Abstract: In this talk we deal with random closed sets in R^d with integer Hausdorff dimension n<d; a problem of interest in many real applications is the study of the so-called mean density of the involved set. Namely, given a random closed set Theta with Hausdorff dimension n, it may well happen that its "induced mean measure" mu(B):=E[H^n(\Theta\cap B] (where H^n denotes the n-dimensional Hausdorff measure) is absolutely continuous with respect to the d-dimensional Lebesgue measure; in such a case, the corresponding density is named the "mean density of Theta". We will give here an overview of some recent results both on its theoretical value and on its estimation in the non-stationary setting; to this aim a stochastic version of the Minkowski content notion will play a fundamental role.

Seminario Cretarola
by Sabrina Mulinacci 05 Mar '15

05 Mar '15

Cari colleghi, Giovedì 12 marzo 2015 ore 12 in aula IV Via Belle Arti 41, Bologna Alessandra Cretarola dell'Università di Perugia terrà un seminario dal titolo: “Risk-minimizing hedging strategies for unit-linked life insurance contracts under partial information” Abstract: We study the problem of hedging unit-linked life insurance contracts in incomplete markets when there are restrictions on the available information by using the local risk-minimization approach. This type of insurance contract is closely related to the financial market since benefits depend on the development of a certain stock price. Then, it makes sense to consider the combined model given by the underlying semimartingale model of financial market and the insurance portfolio. Firstly, we refer to the case of complete information on the insurance portfolio and a limitative knowledge on the financial market. More precisely, we assume that, at any time, the insurance company has access to the information about the number of policy-holders who are still alive but it has a partial information about the stock prices. We characterize the risk-minimizing hedging strategy for pure endowment contracts when the underlying price process is expressed in units of the numéraire portfolio and the mortality hazard rate is a deterministic function, and then we compute it explicitly in a Markovian jump-diffusion driven market model. Next, we consider the case where there are restrictions on the information concerning the insurance portfolio. In particular we assume that, at any time, the insurance company has a complete knowledge of the financial market and may observe the number of deaths from a specific portfolio of insured individuals but not the mortality hazard rate, which may depend on unobservable exogenous stochastic factors. We characterize the locally risk-minimizing hedging strategy for pure endowment and term insurance contracts in terms of the projection of the survival process on the information flow. Finally, we see that in a Markovian framework, this leads to a filtering problem with point process observations. The talk is based on joint works with Claudia Ceci and Katia Colaneri. Un caro saluto a tutti Sabrina Mulinacci

Saleri" VI piano - Dipartimento di Matematica, Politecnico di Milano, nell'ambito delle iniziative MOX, si svolgerà il seguente seminario: Relatori: J. J. Egozcue, Dept. Matematica Aplicada III, U. Politecnica de Catalunya, Barcelona, Spain e V. Pawlowsky-Glahn, Dept. Informatica, Matematica Aplicada i Estadistica, U. de Girona, Spain Titolo: Understanding Bayes spaces Abstract: Bayes spaces contain equivalence classes of sigma-additive measures. Two measures are equivalent when they are proportional. These measures are represented by densities and vector space operations are defined. Probability measures and density functions are included in these spaces. When the densities are log-square-integrable, they are in a Hilbert space called B^2. Bayes spaces and associated Hilbert spaces B^2 have been developed in a theoretical way, but there is still a long way to understand the implications of the theory, as well as to develop potential applications. The talk is aimed at reviewing the theory and giving some examples of distributions for which the B^2 distance can be easily obtained. These examples show the variety of distribution supports that can be dealt with the theory. An application to grain size distribution is presented. The goal is to decide whether different populations have different mean distribution. Tutti gli interessati sono invitati a partecipare.

avviso di seminario

04 Mar '15

Mi scuso per eventuali ricezioni multiple Avviso di seminario Relatore: Radu Craiu Department of Statistical Sciences University of Toronto Titolo: Bayesian Inference for Conditional Copula models with Continuous and Binary Responses Dove e Quando: mercoledì 11 marzo ore 11.30 Aula Fanfani (quinto piano, edificio Economia) Viale del Castro Laurenziano 9, Roma Abstract: The conditional copula device allows the use of copula models in the study of dependence between response variables in regression settings. We consider situations in which the dependence structure varies with covariates and we introduce a Bayesian model that allows for joint estimation of the marginal and joint models. The dependence between the copula parameter and the covariates is modeled via polynomial splines. Extensions to multiple covariates are implemented via additive models. We discuss the computation algorithm required for inference and demonstrate the performance of model selection techniques on simulated and real data.

Ciclo Seminari Probabilita` e Statistica - PASCAL - 4 marzo 2015
by Valentina Cammarota 27 Feb '15

27 Feb '15

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Mercoledì 4 Marzo - ore 15.00 Aula D'Antoni 1101 Dipartimento di Matematica Università di Roma Tor Vergata Speaker: Claudio Durastanti - Università di Tor Vergata Title: Spherical wavelets: an overview and some applications. Abstract: Our aim is to describe the construction of wavelets over the q-dimensional sphere featuring strong concentration properties in the spatial domain, introduced in literature as needlets by Narcowich, Petrushev, Ward (2006 a,b). We will also discuss some of their statistical applications: the study of quantitative central limit theorems for some linear and nonlinear statistics built from wavelet coefficients evaluated on spherical Poisson processes of arbitrary dimension. This purpose is attained by merging the Stein-Malliavin approach (introduced in the seminal paper by Peccati, Sanz-Solè, Taqqu and Utzet (2011)) and the properties of the needlets. We will also discuss some examples: the thresholding and the study of variance in nonparametric density estimation framework and the so-called Sobolev tests for uniformity. This is a joint work with Solesne Bourguin, Domenico Marinucci and Giovanni Peccati. Tutti gli interessati sono invitati a partecipare.
