17 May '18

Con preghiera di diffusione >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Dear Colleagues, a session entitled Numerical methods and quantitative finance: new perspectives and applications(NM)<http://amases2018.uniparthenope.it/files/NM.pdf> will take place during the AMASES Annual Conference, which will be held in Naples on September 13-15, 2018 (http://amases2018.uniparthenope.it/) In recent years the research for mathematical tools to be applied in financial contexts has gained additional importance. In fact the latest financial crisis has highlighted the need for a more scientific approach to the problem of pricing and risk control. Moreover, we can now take advantage of more advanced statistical and mathematical skills and of the availability of numerical techniques and faster computer systems. The aim of this special session is to discuss recent advances and application in this field. Theoretical and empirical papers are welcome. It is a great pleasure to invite you to submit an extended abstract. To be considered for the session, please submit your abstract by specifying the session code (NM) in the file name (NM-[surname of author who will present the paper].pdf). Please refer to the official web page of the conference for further details on the submission. Important dates: May 30, 2018: deadline for abstract submission June 11, 2018: notification of acceptance June 18, 2018: early registration July 2, 2018: late registration For information, please contact: Chiara Guardasoni - chiara.guardasoni(a)unipr.it Daniele Marazzina - daniele.marazzina(a)polimi.it Simona Sanfelici - simona.sanfelici(a)unipr.it We are looking forward to meeting you in Naples.

Seminario di G. Giacomin a Milano-Bicocca (29 maggio 2018)
by Francesco Caravenna 17 May '18

17 May '18

Martedì 29 maggio 2018 alle ore 14:30 Giambattista Giacomin (Université Paris Diderot) terrà un seminario dal titolo "On phase transitions in disordered systems and singular behavior of Lyapunov exponents" Aula 3014, Dipartimento di Matematica e Applicazioni (edificio U5, terzo piano, via Cozzi 55, Milano) Università di Milano-Bicocca Trovate il sommario di seguito. Tutti gli interessati sono invitati a partecipare. Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%% Abstract: Understanding the effect of disorder on phase transitions and crtical phenomena is a challenging problem that has been repeatedly considered in the phyisics literature. In this domain there is a highly non trivial model that takes the center stage because it is considered to be «exactly solvable». It is the two dimensional Ising model with a special type of disorder («columnar disorder»). I will provide an introduction to this model and to what has been conjectured about it. I will also explain why the exact solvability claim is an overstatement. The solvability aspect in fact is limited to the reduction of the problem to another one - the computation of the Lyapunov exponent of a certain product of two by two random matrices - that seems (and probably is) much easier. In collaboration with Francis Comets and Rafael Greenblatt, we have made some progress toward understanding this product of random matrices. The main aim of the talk is explaining these results and what they imply on the two dimensional Ising model with columnar disorder. %%%%%%%%%%%%%%%%%%%%%%%%%% _________________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca Via Cozzi 55, 20125 Milano, Italy http://www.matapp.unimib.it/~fcaraven/ _________________________________________

Colloquium di Balint Toth a Roma Tre il 23 maggio alle 16
by Pietro Caputo 15 May '18

15 May '18

COLLOQUIUM DI MATEMATICA Balint Toth (University of Bristol, UK and Renyi Institute, Budapest) Titolo: Invariance principle for the random Lorentz gas beyond the [Boltzmann-Grad / Gallavotti-Spohn] limit Mercoledi' 23 Maggio 2018 ORE 16:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Aula F, primo piano, edificio Aule - Largo San Leonardo Murialdo,1 Abstract Let hard ball scatterers of radius $r$ be placed in $mathbb R^d$, centred at the points of a Poisson point process of intensity $rho$. The volume fraction $r^d rho$ is assumed to be sufficiently low so that with positive probability the origin is not trapped in a finite domain fully surrounded by scatterers. The Lorentz process is the trajectory of a point-like particle starting from the origin with randomly oriented unit velocity subject to elastic collisions with the fixed (infinite mass) scatterers. The question of diffusive scaling limit of this process is a major open problem in classical statistical physics. Gallavotti (1969) and Spohn (1978) proved that under the so-called Boltzmann-Grad limit, when $r to 0$, $rho to infty$ so that $r^{d-1}rho to 1$ and the time scale is fixed, the Lorentz process (described informally above) converges to a Markovian random flight process, with independent exponentially distributed free flight times and Markovian scatterings. It is essentially straightforward to see that taking a second diffusive scaling limit (after the Gallavotti-Spohn limit) yields invariance principle. I will present new results going beyond the [Boltzmann-Grad / Gallavotti-Spohn] limit, in $d=3$: Letting $r to 0$, $rho to infty$ so that $r^{d-1}rho to 1$ (as in B-G) and simultaneously rescaling time by $T sim r^{-2+epsilon}$ we prove invariance principle (under diffusive scaling) for the Lorentz trajectory. Note that the B-G limit and diffusive scaling are done simultaneously and not in sequel. The proof is essentially based on control of the effect of re-collisions by probabilistic coupling arguments. The main arguments are valid in $d=3$ but not in $d=2$. Joint work with Chris Lutsko (Bristol)

Seminario at Scuola Normale Superiore, Prof. Jean Jacod, Université Paris 6, Pierre et Marie Curie (17-05-2018)
by Giulia 11 May '18

11 May '18

Dear all, On Thursday, 17 May 2018 — at 14:00 — at the Scuola Normale Superiore (Room: Aula Fermi) Prof. Jean Jacod (Université Paris 6, Pierre et Marie Curie) will hold the following Seminar: Title : Modeling asset prices: small scale versus large scale Abstract: A typical model for the price of financial asset, allowing for explicit or numerical computation of option prices, hedging, calibration, etc... , describes the price with an horizon of months or years. In contrast, a very active topic now is concerned with models for tick prices or order books. The structure of the price at the microscopic level is very di_erent from the structure of the usual (often continuous) semimartingales used at a macroscopic level. In particular the microscopic prices evolves on the tick grid, usually going up or down by one tick only. Our aim is to see how it is possible to reconcile the two viewpoints, using a scaling limit of tick-level price models. We will see that this question (going back to the thesis of Bachelier, in a sense) raises a number of non trivial questions if we want a reasonably simple microscopic model, together with a macroscopic model exhibiting stochastic volatility or jumps or a drift. (Joint work with Yacine Ait-Sahalia). Fill free to forward this announcement to your colleagues.

Seminari SOYER e POLSON al CNR IMATI - Milano - 3 Maggio
by antonio.pievatolo＠cnr.it 02 May '18

02 May '18

Ricordo i seguenti seminari che si svolgeranno presso CNR IMATI, via Alfonso Corti 12, Milano, Aula A Giovedì 3 maggio 2018, ore 15:00 - 16:30 [notare il cambio di aula; gentilmente scrivere a simona(a)mi.imati.cnr.it se si intende partecipare] 1) Refik Soyer, School of Business, George Washington University ore 15:00-15:45 BAYESIAN MODELING OF NON GAUSSIAN MULTIVARIATE TIME SERIES Abstract: Modeling of multivariate non Gaussian time series of correlated observations is considered. In so doing, we focus on time series from multivariate counts and durations. Dependence among series arises as a result of sharing a common dynamic environment. We discuss characteristics of the resulting multivariate time series models and develop Bayesian inference for them using particle filtering and Markov chain Monte Carlo methods. We illustrate application of the proposed approach using conditionally multivariate Poisson and gamma time series. Joint work with Tevfik Aktekin, University of New Hampshire and Nicholas Polson, University of Chicago 2) Nicholas Polson, Booth School of Business, University of Chicago ore 15:45-16:30 DEEP LEARNING: A BAYESIAN PERSPECTIVE Deep learning is a form of machine learning for nonlinear high dimensional pattern matching and prediction. By taking a Bayesian probabilistic perspective, we provide a number of insights into more efficient algorithms for optimisation and hyper-parameter tuning. Traditional high-dimensional data reduction techniques, such as principal component analysis (PCA), partial least squares (PLS), reduced rank regression (RRR), projection pursuit regression (PPR) are all shown to be shallow learners. Their deep learning counterparts exploit multiple deep layers of data reduction which provide predictive performance gains. Stochastic gradient descent (SGD) training optimisation and Dropout (DO) regularization provide estimation and variable selection. Bayesian regularization is central to finding weights and connections in networks to optimize the predictive bias-variance trade-off. To illustrate our methodology, we provide an analysis of international bookings on Airbnb. Finally, we conclude with directions for future research.

seminario Marco Patacca in Bicocca
by fabio bellini 02 May '18

02 May '18

Il giorno venerdì 11 maggio alle ore 14.30 presso la Aula Seminari 4026 del DISMEQ al IV piano dell'edificio U7, il dott. Marco Patacca della Università di Perugia terrà un seminario su "Bitcoin prices and market attention" Abstract In this work we measure market attention by applying several filters on time series for the trading volume or the SVI Google searches index. We analyze relative impact of these measures either on the mean or on the variance of Bitcoin returns by fitting non linear econometric models to historical data from January 1, 2012 to December 31, 2017; two non-overlapping subsamples are also considered. Outcomes confirm our conjecture that market attention has an impact on Bitcoin returns. Specifically, trading volume related measures affect both the mean and the conditional variance of Bitcoin returns while internet searches volume mainly affects the conditional variance of returns. Motivated by these evidences we propose a continuous time model for Bitcoin price, we obtain an approximate formula for the likelihood and we fit the model to historical data (joint work with Gianna Figà-Talamanca). Tutti gli interessati sono invitati a partecipare. -- Prof. Fabio Bellini Department of Statistics and Quantitative Methods University of Milano-Bicocca Via Bicocca degli Arcimboldi 8, 20126 Milano 0039-2-64483119 http://scholar.google.it/citations?user=P61L8P4AAAAJ&hl=it

A Winter Day in Probability and Statistical Physics
by Francesca Romana Nardi 27 Apr '18

27 Apr '18

Carissimi, stiamo preparando la prossima giornata di seminari del 16 Marzo 2018 (terzo incontro della serie di giornate sulla probabilita` e le sue applicazioni alla Fisica, Biologia e Scienze sociali). Ricordo che ciascuno oratore fara` una lezione introduttiva e divulgativa di 45 minuti pensata proprio per i non esperti, seguita da altri 45 minuti di tipo seminario (vedi programma). Per maggiori informazioni e aggiornamenti sulle giornate passate e future abbiamo istituito una pagina web che vi invitiamo a visitare periodicamente. http://web.math.unifi.it/users/fnardi/seminari/ A WINTER DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 16 March 2018 Lecturers: Frank den Hollander (Leiden) and Giovanni Peccati (Luxenbourg) Location: Aula Magna di Via S. Gallo 10, Firenze Prof. Frank den Hollander (Leiden University) Title: Large deviations for the Wiener sausage Abstract: The Wiener sausage is the 1-environment of Brownian motion. It is an important mathematical object because it is one of the simplest non-Markovian functionals of Brownian motion. The Wiener sausage has been studied intensively since the 1970's. It plays a key role in the study of various stochastic phenomena, including heat conduction, trapping in random media, spectral properties of random Schrödinger operators, and Bose-Einstein condensation. In these lectures we look at two specific quantities: the volume and the capacity. After an introduction to the Wiener sausage, we show that both the volume and the capacity satisfy a downward large deviation principle. We identify the rate and the rate function, and analyse the properties of the rate function. We also explain how the large deviation principles are proved with the help of the skeleton approach. Joint work with Michiel van den Berg (Bristol) and Erwin Bolthausen (Zurich). Giovanni Peccati (University of Luxembourg) Title: Stein's method and stochastic geometry Abstract: The so-called 'Stein's method' for probabilistic approximations is a collection of powerful analytical techniques, allowing one to explicitly assess the distance between the distributions of two random objects, by using caracterizing differential operators. Originally developed by Ch. Stein at the end of the sixties for dealing with one-dimensional normal approximations under weak dependence assumptions, Stein's method has rapidly become a crucial tool in many areas of modern stochastic analysis, ranging from random matrix theory and random graphs, to mathematical physics, geometry, combinatorics and statistics. In the first part of my talk, I will provide a self-contained introduction to Stein's method for normal approximations, by focussing on some connection with generalised integration by parts formulae, both in a continuous and discrete setting. In the second part of my talk, I will present some recent applications of Stein's method in stochastic geometry, with specific emphasis on the geometry of random fields, and on random geometric graphs.

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 4 Maggio 2018, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Kolyan RAY (King’s College London) ESTIMATING THE MEAN RESPONSE IN A MISSING DATA MODEL We study semiparametric Bayesian estimation of the mean response in a binary regression model with missing observations. We allow some dependence between the missingness and response mechanisms, which we assume are conditionally independent given some measured covariates (i.e. unconfoundedness). This model has applications in biostatistics and causal inference. We show that the marginal posterior distribution for the mean response arising from product priors on the different model parameters satisfies a semiparametric Bernstein-von Mises theorem under some conditions. We also propose a more involved prior geared towards estimating this specific functional. This is joint work with Aad van der Vaart. ------------------------------------------------ Tutti gli interessati sono invitati a partecipare. Il seminario è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.

seminario Dott. Luca Gonzato

Si avvisa che il giorno mercoledì 2 maggio alle ore 14.30 presso l’Università di Milano- Bicocca (via degli Arcimboldi 8 - edificio U7, quarto piano- aula seminari 4026) si terrà il seguente seminario: Speaker: Luca Gonzato (Dismeq, Università di Milano-Bicocca) Titolo: “ Filtering and Calibrating a Self-Exciting Jump Diffusion Model for Oil Price by a Particle Markov Chain Monte Carlo Method ” Abstract: In this paper we propose a self-exciting jump diffusion model for oil price dynamics based on a Hawkes-type process. In particular, the jump intensity is stochastic and path dependent; so a jump will increase the probability of observing a new jump and this feature of the model aims at explaining the jumps clustering effect. Our model is very similar to that proposed by Hainaut & Moraux (2017) for equity market, although we assume the jump size normally distributed. Moreover, our filtering and calibration method relies on a different procedure. Indeed, we filter the latent jump intensity and estimate the model parameters according to a Particle Markov Chain Monte Carlo method proposed by Andrieu, Doucet & Holenstein (2010), which is well suited for nonlinear non-Gaussian dynamical models. Finally, we provide numerical simulations in order to test our approach. Joint work with Carlo Sgarra. Tutti gli interessati sono invitati a partecipare.

Seminario di Jacopo Corbetta in Bicocca
by Francesco Caravenna 26 Apr '18

26 Apr '18

Martedì 8 maggio 2018 alle ore 11:00 Jacopo Corbetta (Zeliade System) terrà un seminario dal titolo "Robust calibration and arbitrage free interpolation of SSVI slices" Aula 4026, IV piano dell'edificio U7 Dipartimento di Statistica e Metodi Quantitativi Via Bicocca degli Arcimboldi 8, Milano Trovate il sommario di seguito. Tutti gli interessati sono invitati a partecipare. Francesco Caravenna %%%%%%%%%%%%%%%%%% We describe a robust calibration algorithm of a set of SSVI (Surface Stochastic Volatility Inspired) slices (i.e. a set of 3 SSVI parameters θ, ρ, ϕ attached to each option maturity available on the market), which grants that these slices are free of Butterfly and Calendar-Spread arbitrage. Given such a set of consistent SSVI parameters, we show that the most natural interpolation/extrapolation of the parameters provides a full continuous volatility surface free of arbitrage. The numerical implementation is straightforward, robust and quick, yielding an effective, parsimonious solution to the smile problem, which has the potential to become a benchmark one. %%%%%%%%%%%%%%%%%% _________________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca Via Cozzi 55, 20125 Milano, Italy http://www.matapp.unimib.it/~fcaraven/ _________________________________________

International Conference in Venice - CALL FOR PAPERS
by Monica Billio 22 Apr '18

22 Apr '18

CREDIT2018 <http://www.greta.it/credit/credit2018/credit2018.htm> *GRETA Associati *(Venice, Italy), the *European Investment Fund *(EIF, Luxembourg), *European DataWarehouse*(Frankfurt am Main, Germany) and *Intesa Sanpaolo *(Milan, Italy) are co-sponsors of a Conference to be held in Venice on September 27-28, 2018. The objective of the Conference is to bring together academics, practitioners and PhD students working in the area of risk management. The conference will provide an opportunity for participants engaged in research at the forefront of this area to discuss both the causes and implications of recent events in financial markets and may, in turn, suggest fruitful directions for future research. The Conference, organised under the auspices of the *Department of Economics of the University Ca’ Foscari of Venice*, *ABI - Italian Banking Association *and *European Investment Bank*, is the *seventeenth* of a series dedicated to various aspects of credit risk. //Since 2007, the financial crisis has triggered deep changes of various kinds. Central banks have experimented with new monetary policies (low interest rates, quantitative easing, forward guidance...). In the meantime the first steps towards a more neutral monetary policy are taken. The banking industry has had to develop new asset management strategies and to adjust its credit allocation practices in order to cope with a new environment characterized, in particular, by a prolonged period of very low risk-free returns. Meanwhile, regulatory frameworks have been reshaped all around the world, with the introduction of new requirements or guidelines including regulation on credit impairment provisioning. All t////hese changes have called for a substantial amount of research to improve the knowledge of the mechanisms at play during the crisis, to design adapted policy tools and to provide a better description of the new economic and financial environment.////// The organizers encourage submissions of papers on any topic within the overall theme of the conference and in the following areas in particular: * Loan level data and credit risk analysis: credit registries; big data analytics; credit risk measurement; credit risk modelling; * Financial regulation and credit cycles: macro-prudential regulation; banking cycles; bank business models; rational inattention; * Macro-economic determinants of SMEs’ credit risk and SME loan portfolios: ECB policy; macro-parameters for SMEs’ credit risk; industry sector specialization; loan portfolio allocation; * IFRS9, credit impairments and SME financing: expected credit loss; internal models versus standardized approach; procyclicality; * The economic impact of government support measures (i.e. Credit Guarantee Schemes, Venture Capital): availability; real effects; inequality; * Monetary policy, financial regulation and credit cycles: unconventional monetary policy; monetary policy normalization; macro-prudential tools; banking cycles; ·Macro-prudential regulation and real estate valuation: macro-prudential tools; loan-to-value; loan-to-income; collateral value; real estate prices. The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Tor Jacobson *(Sveriges Riksbank), *Robert C. Merton* (MIT Sloan School of Management), and *Guillaume Plantin *(Sciences Po & CEPR). The Conference will also feature a panel discussion on researchers' and practitioners' views of the major outstanding problems.

DGA-Inria PhD position at Sophia-Anitipolis, France. Deadline : April 29th 2018. Contact : Josiane ZERUBIA, Inria-SAM
by Marianne Clausel 21 Apr '18

21 Apr '18

*Application :* For more information and application, please contact before April 29 th , 2018: Josiane ZERUBIA, Inria-SAM http://www-sop.inria.fr/members/Josiane.Zerubia/index-eng.html email: Josiane.Zerubia(a)inria.fr *Title:* Stochastic Geometry for Multiple Object Detection and Tracking in High Resolution Multi-Source Data Sets for Wide Area Surveillance Applications *Abstract:* Unmanned aerial vehicles and low-orbit satellites, including cubesats, are increasingly used for wide area surveillance which results in large amounts of multi- source data (videos) that have to be processed and analyzed. These sensor platforms capture vast ground areas at roughly 2 frames per second. The number of moving objects in such data is typically very high, accounting for up to thousands of objects. Multiple objects tracking has traditionally been a major area of research in the computer vision field, but this type of data poses new, specific, tracking related challenges. The large number of small objects coupled with the reduced frame rate of the video, illumination changes and image registration provide significant sources of errors. Numerous motion models and state estimation methods like the Kalman filter or the particle filter have been proposed for object tracking. Classical trackers such as the Multiple Hypothesis Tracker or the Joint Probabilistic Data Association Filter have been employed to solve the data association problem between multiple detections. Both approaches work on a set of data association hypothesis. A strong limitation of these methods is that past decisions cannot be updated when new information is available. One way to cope with this problem is to use a sliding temporal window to perform tracking taking into account both past and future information and hence, removing the causality of the result. Recently, a new spatio-temporal marked point process model specifically adapted to the problem of multiple objects tracking has been developed by Craciun et al. [1]. Craciun et al. use ellipses to model the objects, boats or cars for instance, adding a non-geometric mark to facilitate the association between objects in different frames. Nevertheless one important drawback of the above-mentioned model is that constant velocity of the moving objects is a necessary prior hypothesis to deal with the corresponding density function to be optimized. In this PhD thesis we propose to get rid of this constraint by extending the previous model of Paula Craciun . [1] P. Craciun, M. Ortner, and J. Zerubia.

PhD Thesis : Towards hybrid and explainable recommender systems mixing content analysis and collaborative filterings, Project OLKI Lorraine Université d'Excellence, France
by Marianne Clausel 20 Apr '18

20 Apr '18

*General context* Over the last twenty years, an increasing attention has been paid to recommender systems, widely popularized by the Netflix Challenge. The main goal of a recommender system is to provide some users, with personalized products, taking into account their profile and preferences. Recent challenges are about the recommendation of products very complex to describe : jobs, partners... Their characteristics can mix heterogeneous features: quantitative (as ratings) and/or qualitative (as reviews). Moreover, new questions are emerging about explainability of algorithms. Nowadays, Artificial Intelligence algorithms are democratized in our erveyday life, and consumers want to understand the decision resulting from these algorithms (why this decision and not another one ?) as well as quantify the importance of each factor (element) in the decision process (which element is the most important/sensitive). They require more /explainability/ of AI algorithms. In addition, the new European legislation on data protection foresees to impose more /transparency/ to Artificial Intelligence algorithm. The law envisages to make compulsory the agreement of users for using personal data, which will reduce the amount of data that can be collected about users. The customer will also have to be informed about the way their personal data is used. From the algorithms point of view, the decrease of data will impact the quality of the recommmendations. All these changes, will impact shortly and significantly the design of algorithms. In this thesis, we aim at designing and implementing new explainable and transparent recommender systems for complex products, in the frame of data sparsity. *Scientific challenges and program* The challenges are four fold : - *Definition*, in a quantitative way, of the concept of transparency, and develop statistical methods to automatically quantify the transparency degree of an algorithm. - *Classification* of recommender systems from the literature, from the transparency point of view and/or robustness degree with respect to missing data - *Conception* of new hybrid and explainable recommender systems, robust to sparse data. The products being complex, the heterogeneous descriptions of the products, as well as the multi-sources of information, will be used to construct understandable explanation. Especially, natural language processing, and hybrid (content/social) approaches will be studied. The algorithms will also be able to quantify the weights and the sensitivity of each factor in the final decision. - *Constitution *of data sets, allowing to evaluate transparency of recommender systems *Application* \noindent The application should include a brief description of research interests and past experience, a CV, degrees and grades, a copy of Master thesis (or a draft thereof), motivation letter (short but pertinent to this call), relevant publications (if any), and other relevant documents. Candidates are encouraged to provide letter(s) of recommendation or contact information to reference persons. Please send your application *before 12 May 2018* in one single pdf to : armelle.brun(a)univ-lorraine.fr marianne.clausel(a)univ-lorraine.fr The application of the preselected candidates will be reviewed by the Doctoral School IAEM of University of Lorraine in June 2018 for completing the selection process. *Practical informations* *Duration: *3 years (full time position) *Starting date:* October, 2018 *Supervisors* A. Brun, University of Lorraine/LORIA, France, https://members.loria.fr/ABrun/ M. Clausel, University of Lorraine/IECL, France, https://sites.google.com/site/marianneclausel/ *Working Environment* The PhD candidate will work between the Probability and Statistic team of the IECL lab and the KIWI Team of the LORIA lab which are two leading institutions, respectively in Mathematics and Computer Science in France. The two labs are both located at Nancy, France on the same campus. The Probability and Statistic team of IECL is working on interdisciplinary projects involving probabilistic modeling and inference methods, with a focus on many applications as textual datas, biology, spatial datas... The KIWI team of LORIA is a dynamic group working on recommender system and connected scientific domains over 20 researchers (including PhD students) and that covers several aspects of the subject from theory to applications, including statistical learning, data-mining, and cognitive science. *Location* : Nancy, which is the capital of Lorraine in France, with excellent train connection to Luxembourg (1h30) and Paris (1h30). *Salary after taxes: *around 1600 euros.

Segnalo i seguenti seminari che si svolgeranno presso CNR IMATI, via Alfonso Corti 12, Milano, Aula Expo Giovedì 3 maggio 2018, ore 15:00 - 16:30 1) Refik Soyer, School of Business, George Washington University ore 15:00-15:45 BAYESIAN MODELING OF NON GAUSSIAN MULTIVARIATE TIME SERIES Abstract: Modeling of multivariate non Gaussian time series of correlated observations is considered. In so doing, we focus on time series from multivariate counts and durations. Dependence among series arises as a result of sharing a common dynamic environment. We discuss characteristics of the resulting multivariate time series models and develop Bayesian inference for them using particle filtering and Markov chain Monte Carlo methods. We illustrate application of the proposed approach using conditionally multivariate Poisson and gamma time series. Joint work with Tevfik Aktekin, University of New Hampshire and Nicholas Polson, University of Chicago 2) Nicholas Polson, Booth School of Business, University of Chicago ore 15:45-16:30 DEEP LEARNING: A BAYESIAN PERSPECTIVE Deep learning is a form of machine learning for nonlinear high dimensional pattern matching and prediction. By taking a Bayesian probabilistic perspective, we provide a number of insights into more efficient algorithms for optimisation and hyper-parameter tuning. Traditional high-dimensional data reduction techniques, such as principal component analysis (PCA), partial least squares (PLS), reduced rank regression (RRR), projection pursuit regression (PPR) are all shown to be shallow learners. Their deep learning counterparts exploit multiple deep layers of data reduction which provide predictive performance gains. Stochastic gradient descent (SGD) training optimisation and Dropout (DO) regularization provide estimation and variable selection. Bayesian regularization is central to finding weights and connections in networks to optimize the predictive bias-variance trade-off. To illustrate our methodology, we provide an analysis of international bookings on Airbnb. Finally, we conclude with directions for future research.

Seminario di Scotti a Firenze, lunedì 23 aprile 14.30: Branching Processes with applications in Finance
by Cecilia Mancini 19 Apr '18

19 Apr '18

Il giorno lunedì 23 aprile, ore 14.30 Simone Scotti, Università Diderot di Parigi (Parigi 7), terrà il seminario dal titolo Branching Processes with applications in Finance presso l'edificio D6, via delle Pandette 9, 50127 Firenze, del polo di Novoli, in aula D6/104. Tutti gli interessati sono cordialmente invitati a partecipare Abstract: I processi di Branching con immigrazione (CBI) sono una classe di processi ben studiati in probabilità. In particolare i lavori di Dawson e Li hanno fornito una scrittura esplicita per l'EDS di un CBI generale e provato l'unicità della soluzione. Utilizzeremo questa scrittura per proporre un estensione del modello CIR includendo una parte di salto nel meccanismo di Branching, considerando in particolare il caso alpha-stabile per la sua parsimonia e la coerenza con i dati statistici. Questo modello ha mostrato di essere capace di riprodurre la persistenza dei bassi tassi d'interesse malgrado la presenza di importanti grandi salti. L'applicazione principale a cui ci interesseremo è un estensione del modello di Heston includendo salti auto-eccitati sul processo di varianza. Studiamo in particolare il comportamento della volatilità implicita dei derivati dell'azione e di quelli dei variance swap. Testiamo il modello sui dati del VIX. Basato su piu lavori con Guillaume Bernis, Ying Jiao, Chunhua Ma, Carlo Sgarra e Chao Zhou.

seminario presso l'Università di Milano-Bicocca, 4 maggio 2018
by daniela bertacchi 18 Apr '18

18 Apr '18

Il giorno 4 maggio alle ore 14:30 in aula 3014 del Dipartimento di Matematica e Applicazioni dell'Università di Milano-Bicocca, la dottoressa Sophie Hautphenne dell'Università di Melbourne e Politecnico di Losanna, terrà un seminario dal titolo: The probabilities of extinction in a branching random walk on a strip Tutti gli interessati sono invitati a partecipare. Abstract. We consider a class of multitype Galton-Watson branching processes with countably infinite type set X whose mean progeny matrices have a block lower Hessenberg form. For these processes, we derive partial and global extinction criteria. Our approach involves embedding a finite-type explosive Galton-Watson process in a varying environment in the original infinite-type process, and then establishing asymptotic relationships between the two processes. We study the probability of extinction in sets of types A ⊆ X , q(A). In particular, we develop conditions for q(A) to be different from the global and partial extinction probability vectors. We present an iterative method to compute the vectors q(A), and investigate their location in the set of fixed points of the progeny generating vector.

The usage of continuous time models allows us to manage irregularly spaced data (for example in financial time series due to weekends, holidays and breaks during the trading hours) without considering any missing data imputation method. Several routines for simulation and estimation are discussed. The flexibility of the package is due to the fact that the user is allowed to choose several parametric L\'evy distributions for the increments. Tutti gli interessati sono invitati a partecipare.
