**************************************************************** STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO **************************************************************** Venerdi' 23 Gennaio 2015 alle ore 12:00, presso la sala rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Jean-Bernard SALOMOND (CWI, Netherlands) BAYESIAN NONPARAMETRIC TESTING FOR EMBEDDED HYPOTHESES WITH APPLICATION TO SHAPE CONSTRAINS Abstract: If Bayesian nonparametric methods have received a great interest in the literature, only a few is known for testing nonparametric hypotheses, and especially the asymptotic properties of such tests. The problem of testing between two nonparametric hypotheses is known to be difficult, but the problem becomes even harder when the hypotheses are embedded. In this work, we propose a method to circumvent these difficulties with a special focus on shape constrains testing. We propose an approach that allows us to derive a Bayesian answer to testing problems that has good asymptotic properties and that are easy to use in practice. Furthermore, from our method, we can easily derive posterior separation rate of the tests which to our best knowledge has not been studied in the Bayesian literature so far. We apply our approach to several testing problems with a special attention to the problems of testing for positivity or monotonicity in a nonparametric regression problem. 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.

DATE AND TIME Wednesday, January 21, 2015 at 3:30 PM PLACE Dept. Computer Science - UniVr - Strada le Grazie 15 - Ca'Vignal 2 - Room M *Michele Bonollo* *Market Risk and the FRTB (R)-Evolution ? Review and Open Issues* ** We will present the so called * fundamental review of trading book *(FRTB) a new market risk approach published by the Basel commitee directive (i.e. papers 265 and 305). Such an approach implies that banking institutions have to move from the standard Value at Risk (VaR, quantile based) approach to the Expected Shortfall (ES, average over the tail) methodology as a measure of risk. The theoretical differences are well known, but some implementaion issues are very challenging for the banking industry, such as the backtesting procedures. In the seminar after a thoretical revew some practical cases will be discussed.

Seminario di Paolo Foschi presso Prometeia - Bologna
by Giacomo Scandolo 13 Jan '15

13 Jan '15

Il giorno Giovedì 22 Gennaio 2015, alle ore 14:30 presso la sede di Prometeia (sala grande, primo piano) via G.Marconi 43, Bologna Paolo FOSCHI (Università di Bologna) terrà un seminario dal titolo "Forecasting forward price curves in electricity markets: a factor model" Abstract A dynamic factor model for the cross section for italian electricity forward prices is presented. This market is characterised by a small number of quotations for each forward contract and by a large bid-ask spread. Moreover, it is not uncommon to observe inconsistencies in the cross section of forward quoted prices. The aim of the proposed model is twofold. Firstly, this approach allows to filter out noise and to help in identifying inconsistencies. Secondly, it provide a tool to fill-in missing quotations and to unpack forward contract with long delivery into smaller ones (i.e. a quarter or a calendar into its monthly components). The model is built using monthly contracts are used as basic entities and their dynamics is modeled as follows. The cross section of those contracts is decomposed in two set of factors: the first set, which depends on the time-to-delivery, allows to financial structure of the market. The second set, which depends on the actual delivery month, will capture the seasonal component. The parameters of those factors are allowed to be slowly varying to achieve maximal flexibility.

Seminario MAZZONI (RGS & Matematica Applicata)
by Giacomo Aletti 12 Jan '15

12 Jan '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, "Neuromorphic tactile computation" Alberto MAZZONI The Biorobotics Institute, Scuola Superiore S.Anna http://sssa.bioroboticsinstitute.it/user/1627 Abstract: One of the main challenges in upper limb neuroprosthetics is to implement realistic tactile feedback. An emerging trend for tactile feedback is to mimic the neuronal activity of biological mechanoreceptors in order to enable natural learning of feedback. We implemented real-time neuromorphic artificial touch by injecting the raw output of a biomimetic tactile sensor into an Izhikevich neuronal model emulating the firing behavior of mechanoreceptors. The resulting neuromorphic spike trains were able to classify naturalistic textures with high accuracy by mean of Victor Purpura metrics. Crucially, we found that the decoding performance based on neuromorphic spike trains was robust for a broad range of sensing conditions. Being able to categorize naturalistic textures in different sensing conditions, these neurorobotic results pave the way to the use of neuromorphic tactile sensors in future real-life neuroprosthetic applications. ================= 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). Initiatives and updates are published on the website: http://rgs.mat.unimi.it/. -- ------------------------------- Giacomo Aletti, Associate Professor ADAMSS Centre (ex MIRIAM) Advanced Applied Mathematical and Statistical Sciences Department of Mathematics (www.matematica.unimi.it) Via Saldini, 50 20133 Milano, Italy Tel: +39-02-503.16158 Fax:+39-02-503.16090 Cell: +39-340-9739142

by Serena Doria 12 Jan '15

12 Jan '15

*ISIPTA '15 SECOND CALL FOR PAPERS & POSTERS* 9th International Symposium on Imprecise Probability: Theories and Applications 20-24 July 2015 Pescara, Italy Website with up-to-date information on all aspects of the conference: http://www.sipta.org/isipta15 Scientific program contact: isipta15(a)easychair.org Local organization contact: isipta15(a)unich.it *Important Dates* 30 Jan - Paper abstracts & preliminary papers due 13 Feb - Review-ready papers due 31 Mar - Conference hotel pre-reservation deadline 08 Apr - Paper notification 17 Apr - Poster-only abstracts due 06 May - Poster-only notification 29 May - Early-bird registration deadline (?350 full; ?200 student) *Scope & Symposium Format* ISIPTA is the primary international forum to present and discuss new results related to imprecise probability. We welcome both theoretical and applied original contributions. In this edition, we especially welcome papers connecting imprecise probabilities with related research in fields such as economics, philosophy, sociology, and engineering. There will be no parallel sessions. Each paper that is accepted is presented both (i) in a plenary session, meant for a short introduction and a sketch of the context and relevance; and (ii) in a poster session, where ample time is given for in-depth explanation and discussion. The poster-only track provides a second, free format presentation option. It is also open for preliminary results, challenges, etc. *New: non-proceedings papers* To adapt to different publication cultures in different fields, we introduce a new option: the non-proceeding papers. Authors may request that their contribution is not published in the proceedings in case this precludes later publication of an expanded journal version. The PC Board will decide on a case-by-case basis. If accepted, a one-page abstract will be published in the proceedings, and the paper must be freely available on-line (e.g., as a working paper). *Invited Speakers* Massimo Marinacci, AXA-Bocconi Chair in Risk Department of Decision Sciences, Bocconi University, Milan, Italy Itzhak Gilboa, Professor of Economics and Decision Sciences Eitan Berglas School of Economics, Tel-Aviv University, Israel & HEC, Paris, France Peter M. Williams, a Founding Father of Imprecise Probability and Principal BW Mining, Brighton, UK *Special Issue* After the conference, a special issue with a selection of the accepted papers will be published in an expanded version in the International Journal of Approximate Reasoning. *Steering Committee* T. Augustin (LMU München, Germany) + PC Board G. de Cooman (Ghent University, Belgium) S. Doria (University G. d'Annunzio, Italy) + Local Organization E. Miranda (University of Oviedo, Spain) + PC Board E. Quaeghebeur (CWI, Amsterdam, Netherlands) + PC Board T. Seidenfeld (Carnegie Mellon University, USA) We look forward to your contribution and to seeing you in Pescara!
