by Francesco Cesarone 11 Jan '18

11 Jan '18

Dear Colleagues, on 23 January 2018 from 14:00 to 17:00 (Computer Lab, ground floor, Department of Business Studies-Roma Tre University, Via Silvio D'Amico, 77 -00145, Roma), Dr. Francesca Perino, Application Engineer at MathWorks, will hold a min-workshop on "Machine Learning and Big Data Analytics with MATLAB". The attendance of the course is free, but for organizational reasons it is necessary to register to register on the following web page: https://it.mathworks.com/company/events/seminars/ml-da-with-matlab-2373496.… . *Overview* *At the heart of many financial applications are machine learning techniques used for risk classification, economic analysis, credit scoring, time series forecasting, estimating default probabilities, and data mining. Big data represents an opportunity for quantitative analysts and data scientists alike to impact the way organizations make informed business decisions. By building machine learning models that harness big data, a greater level of insight and confidence can be achieved.* *However, implementing and comparing machine learning techniques to choose the best method can be challenging. Furthermore, there is no single approach to solving the many challenges arising from working with big data. MATLAB minimizes these challenges by providing you with a number of built-in functions and tools for quick prototyping, integration, and scaling, to take you from initial prototype all the way to business-critical production system.* *In this session, we will introduce ways of working with big data systems, the different types of machine learning techniques in MATLAB, how to determine the best techniques for your problem by evaluating model performance, and rapidly deploying your machine learning models into production. We will cover several new workflows and data types in MATLAB and the toolboxes that have been designed to address the most common challenges with big data analytics and machine learning.* *Highlights* *Data management and integration with databases, live market data, and big data environments* *Efficient workflows for heterogenous time-series data using new data management capabilities* *Parallel Computing techniques to speed up long-running computations and deal with out-of-memory data* *Predictive modeling and using supervised machine learning techniques to build a credit rating engine* We look forward to meeting you in Roma Tre!

Cordialmente, m.gianfelice p.s: Among the Skills & diploma requested, the successful candidate should possess: - A PhD in Statistics, Applied Mathematics or related fields; - Strong bases on stochastic models including their statistical inference; - An excellent knowledge of R (recommended) or Python (second choice) programming languages; - English proficiency and attitude to work in an international research environment. ---------- Forwarded message ---------- Date: Wed, 10 Jan 2018 14:05:07 +0100 (CET) From: Davide Faranda <davide.faranda(a)lsce.ipsl.fr> Cc: Mathieu Vrac <mathieu.vrac(a)lsce.ipsl.fr> Subject: Postdoctoral Research Associate position: "Postdoctoral Research Associate position ?Laboratoire des Sciences du Clima t et de l?Environnement? (LSCE, Gif-sur-Yvette, France) funded by CEA on "E vent Attribution of Climate Changes with dynamically driven-Stochastic Weather Generators" Dear Colleague, (sorry for cross-posting) please circulate this announcement for a post-doctoral position at LSCE starting Spring 2018 for (at least) 16 months. Applications will be open untill January 31, 2018 Best Regards, Mathieu Vrac, Davide Faranda Postdoctoral Research Associate position ?Laboratoire des Sciences du Climat et de l?Environnement? (LSCE, Gif-sur-Yvette, France) funded by CEA on Event Attribution of Climate Changes with dynamically driven-Stochastic Weather Generators Expected starting date: Spring 2018. Duration: 16 months Context of the position: There is an increasing interest worldwide in assessing the extent to which recent extreme weather and climate events can be solely linked to natural climate variability or be significantly altered in frequency or intensity by human-induced climate change (Stott, 2016). Examples are numerous: Paris flood in June 2016, drought in Central Europe in Summer 2015, or the extremely cold European winter of 2009/10. The usual question is to know to what extent such extremes are linked to climate change, and if they are becoming (or will become) more or less frequent. Therefore, the science of ?event attribution? is evolving rapidly. This postdoctoral position is part of the European ERA4CS ?EUPHEME? project, whose one of the main objectives is to develop state-of-the-art event attribution methods for a range of timescales, and new techniques for evaluating their reliability. The vision of the EUPHEME project is to place extreme weather events in the context of climate variability and change, thereby helping European citizens adapt to a changing climate and mitigate its worst effects. Scientific context: Event attribution relies on comparisons of various statistics of extreme events between a ?factual world? (i.e., the world as we observe it or at least with the real physical forcings) and a ?counter-factual world? (i.e., the world as it would be without one or several given forcings, as human-induced greenhouse gas emissions). Those comparisons are usually performed based on a very high number (1000s of runs) of climate model simulations. One issue is that General circulation models are generally too expensive to be run as long as needed to compute such statistics and at the demanded resolution. Stochastic weather generators (SWGs) are therefore a valid alternative: they are statistical models calibrated on past observations to simulate as many datasets as desired with the same statistical properties [Wilks, 2010, 2012]. Moreover, the dynamics of atmospheric motions depends on the observed atmospheric states. Recently, a technique to measure such state-dependent dynamical properties have been found [Faranda et al., 2017] by the computation of the so-called local dimensions (a measure of the state disorder) and the local persistence. Preliminary studies have shown that such information can be lumped with the statistical model to obtain ?conditional SWGs? (e.g., Wong et al., 2014) providing simulations with a realistic dynamics. Main goals: The goal of the postdoctoral research is to provide both a theoretical framework and a numerical tool to build conditional SWGs driven by dynamical systems properties. - The first step will be to introduce such properties and indicators in simple autoregressive models to mimic the dynamical properties of univariate time series of climate variables and simple dynamical systems. - Those state-dependent indicators will then be used to condition progressively more sophisticated SWGs (e.g., Vrac et al., 2007), up to spatial models (i.e., simulating fields) for climate variables as wind, temperature or precipitation. - At each stage, the different conditional SWGs developed will be applied in an event attribution purpose to evaluate the improvements achieved or still needed, depending on the extreme events of interest. Skills & diploma requested: The successful candidate should possess: - A PhD in Statistics, Applied Mathematics, Statistical Physics, Climate sciences or related field; - Strong bases on stochastic models including their statistical inference; - A basic knowledge of climate dynamics; - An excellent knowledge of R (recommended) or Python (second choice) programming languages; - A basic knowledge of dynamical systems framework will be a plus but is not mandatory; - English proficiency and attitude to work in an international research environment. Geographical location & scientific team: This postdoctoral position will be located at Gif-sur-Yvette (France), in the ?Extremes ? Statistics ? Impacts ? Regionalization? (ESTIMR) scientific research team of the ?Laboratoire des Sciences du Climat et de l?Environnement? (LSCE). The ESTIMR team develops a methodological research aiming to better understand the climate data: statistical analyses of observations and simulations in order to investigate the variability and identify the trends, modelling of extreme events, detection and attribution of their changes, downscaling, bias adjustment of simulations, uncertainty modelling of climate projections, etc. The ESTIMR team leads and participates to international projects, from pure to more applied science project. The main activity of the team relies on the use and development of advanced statistical models via a strong multidisciplinary interaction among climatology, modelling and statistics. How to apply: Applications will be open until January 31, 2018 (or until the position is filled) and have to be submitted by e-mail to M. Vrac (mathieu.vrac[at]lsce.ipsl.fr) and D. Faranda (davide.faranda[at]lsce.ipsl.fr) as soon as possible and must include: - a CV (max 2 pages + Publication list), - A statement of research interests describing why the candidate fits the position (max 2 pages), - The names of at least two references including e-mail addresses and telephone numbers.

Seminario di Probabilità e Statistica Matematica a RM1
by Fabio Spizzichino 09 Jan '18

09 Jan '18

Il Prof. Yaakov Malinovsky (University of Maryland, Baltimore County) terra' un seminario dal titolo *Nested Group Testing Procedures and Generalized GT Problem* Giovedi' 11 Gennaio, ore 14:00, Aula B del Dipartimento di Matematica dell'Università La Sapienza, Piazzale A. Moro, 2 Tutte le persone interessate sono invitate ad intervenire Fabio Spizzichino ================ Abstract Group testing has its origins in the identi cation of syphilis in the US army during World War II. It is a useful method that has broad applications in medicine, engineering, and even in airport security control. Consider a finite population of N units, where unit i has a probability p to be defective. A group test is a simultaneous test on an arbitrary group of units with two possible outcomes: all units are good or at least one of the units is defective. The goal is to construct a procedure which classi fies all units in a given population, with as small as possible expected number of tests. In this talk I shall review previously known results in the group testing literature and present new results characterizing optimality of commonly used nested group testing procedures. In the second part of the talk, the generalized group testing problem (where unit i has a probability p_{i} to be defective) will be discussed as well. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
