2 postdocs in Geometry of Deep Learning and Reinforcement Learning at RIST
by Luigi Malagò 11 Jul '17

11 Jul '17

=========================================================== 2 postdoc positions in Machine Learning (1 year, renewable up to 3 years) Institution: RIST - Romanian Institute of Science and Technology, Cluj-Napoca Keywords: Deep Learning, Reinforcement Learning, Stochastic Optimization, Optimization over Manifolds, Information Geometry, Riemannian Geometry Application deadline: 30 July 2017 (applicants are encouraged to apply earlier) Salary: around 2190 euro net Official announcement: http://rist.ro/en/details/news/postdoc-positions-in-deep-learning-and-machi… =========================================================== Dear colleagues, the Romanian Institute of Science and Technology (RIST) has an opening for 2 postdoc positions, in the context of the DeepRiemann project “Riemannian Optimization Methods for Deep Learning”, funded by European structural funds through the Competitiveness Operational Program (POC 2014-2020). The appointments will be for 1 year, with possible extensions up to 3 years. The DeepRiemann project aims at the design and analysis of novel training algorithms for Neural Networks in Deep Learning, by applying notions of Riemannian optimization and differential geometry. The task of the training a Neural Network is studied by employing tools from Optimization over Manifolds and Information Geometry, by casting the learning process to an optimization problem defined over a statistical manifold, i.e., a set of probability distributions. The project is highly interdisciplinary, with competences spanning from Machine Learning to Optimization, Deep Learning, Statistics, and Differential Geometry. The objectives of the project are multiple and include both theoretical and applied research, together with industrial activities oriented to transfer knowledge, from the institute to a startup or spin-off of the research group. The positions will be part of the new Machine Learning and Optimization group http://luigimalago.it/group.html, which performs research at the intersection of Machine Learning, Stochastic Optimization, Deep Learning, and Optimization over Manifolds, from the unifying perspective of Information Geometry. The group is one of two newly-formed groups in Machine Learning at RIST, where about 20 new postdoctoral research associates and research software developers will be hired by 2018. The official job announcement can be seen here: http://rist.ro/en/details/news/postdoc-positions-in-deep-learning-and-machi… Informal inquiries can be sent to Dr. Luigi Malagò <malago(a)rist.ro>, principal investigator of the DeepRiemann project. Application deadline: 30 July 2017 (applicants are encouraged to apply earlier)

10 Jul '17

---- We apologize for cross posting ---- Dear all, this is just a friendly reminder that *today* is the deadline for early-bird registration to the *11th Scientific Meeting of the CLAssification and Data Analysis Group of the Italian Statistical Society * http://www.cladag2017.unimib.it/ For the 2017 edition of the Conference, the University of Milano-Bicocca, Bocconi University, Politecnico di Milano, University of Milano and Università Cattolica del Sacro Cuore are cooperating and supporting the event, that will be hosted at University of Milano-Bicocca. *Papers* Around 150 papers have been submitted for the Conference, for which the usual blind referee process has been carried out by the Scientific Program Committee, chaired by Francesco Mola. *Keynote speakers:* - J. Sunil Rao, <http://www.biostat.med.miami.edu/people/primary-faculty/sunil-rao> Division of Biostatistics, Department of Public Health Sciences University of Miami, Florida, USA, - *Classified Mixed Model Prediction*- Antony Davison, <http://statwww.epfl.ch/davison/davison.html> Institute of Mathematics, Ecole Poytechnique Federale de Lausanne, Switzerland - *Statistical models for complex extremes*- Roberto Rocci <http://economia.uniroma2.it/faculty/145/rocci-roberto>, Dipartimento di Economia e Finanza, Università degli studi di Tor Vergata, Rome, Italy - *An URV approach to cluster ordinal data* *Young researchers data challenge*Young researchers are invited to a data challenge, at Politecnico di Milano the day before the Conference, say on September 12, and sponsored by Oracle and Data Reply. Amazing prices are announced for the winners! *Statistical Challenges in Big Data & Complex Systems* A satellite Conference will take place on Tuesday September 12, at the University of Milano. More information will be available soon at http://www.cladag2017.unimib.it/ *Social dinner*The social dinner will take place on September 14th, in the *San Nazaro Porch* of the ancient “*Cà Granda*” complex, entrusted to the Tuscan architect Antonio Averlino, known as Filarete. Founded on 12 April, 1456 by the Duke of Milan Francesco Sforza and his wife Bianca Maria, the gigantic complex was built to provide medical care for the city’s poorest people. *Conference Proceedings* The Conference Proceedings will be published in digital edition with ISBN and distributed for free to all the Cladag2017 Participants. *Post conference publications* After the Conference, the Program Committee encourages authors of the best papers to submit an extended version for possible publication in the *Springer Series:* "Studies in Classification, Data Analysis, and Knowledge Organization", or alternatively to submit to a *special issue* of the following journals: Statistical Analysis and Data Mining <http://www.statisticsviews.com/details/journal/2285261/Statistical-Analysis…>, published on behalf of the American Statistical Association <http://www.amstat.org/>, and Statistics and Applications <http://statisticaeapplicazioni.vitaepensiero.it/> Both journals will offer the possibility to publish a selection of the best 10-15 papers presented at CLADAG 2017. Topics covered in these papers should be in line with the aims and scope of the journal and will undergo a regular review process. We look forward to see you in Milan on 12-15 September for CLADAG 2017! The organizing Committee

U7, 2° piano, aula 2061 __________________________________________________________ Abstract: In this presentation we illustrate a novel inferential approach to estimate time-varying parameters of locally stationary time series. This approach is based on costationary combinations, that is, time-varying deterministic linear combinations of locally stationary time series that are second-order stationary. We first review the theory of costationarity and formalize a Generalised Method of Moments estimator for the coefficient vectors. We then use this new framework to derive an estimator for the (time-varying) covariance of locally stationary time series and we show that the new covariance estimator is more efficient than classical estimators exclusively based on the evolutionary cross-periodogram. We confirm our theoretical findings through a simulation experiment. We then present a new analysis of financial log-returns showing that our new estimator is capable to highlight well known economic shocks. As a second example of our approach we finally discuss forecasting of locally stationary time series based on costationary combinations. __________________________________________________________ Cordiali saluti Fulvia Pennoni -- Fulvia Pennoni Department of Statistics and Quantitative Methods University of Milano-Bicocca http://www.statistica.unimib.it/utenti/pennoni/
