Seminar Dunson @BIDSA, Bocconi
by Giacomo Zanella 16 Sep '19

16 Sep '19

We kindly invite you to the following BIDSA seminar: “Learning and exploiting low-dimensional structure in high-dimensional data” David Dunson (Duke University) September 19, 2019 | 12:30 | Room AS03 Bocconi University, Via Roentgen 1, underground floor Abstract: This talk will focus on the problem of learning low-dimensional geometric structure in high-dimensional data. We allow the lower-dimensional subspace to be non-linear. There are a variety of algorithms available for "manifold learning" and non-linear dimensionality reduction, mostly relying on locally linear approximations and not providing a likelihood-based approach for inferences. We propose a new class of simple geometric dictionaries for characterizing the subspace, along with a simple optimization algorithm and a model-based approach to inference. We provide strong theory support, in term of tight bounds on covering numbers, showing advantages of our approach relative to local linear dictionaries. These advantages are shown to carry over to practical performance in a variety of settings including manifold learning, manifold de-noising, data visualization (providing a competitor to the popular tSNE), classification (providing a competitor to deep neural networks that requires fewer training examples), and geodesic distance estimation. We additionally provide a Bayesian nonparametric methodology for inference, using a new class of kernels, which is shown to outperform current methods, such as mixtures of multivariate Gaussians. Speaker: David Dunson is Arts and Sciences Distinguished Professor of Statistical Science and Mathematics at Duke University. He is known for his broad spanning contributions to statistical methodology, with a particular focus on novel modeling frameworks and Bayesian approaches that are motivated by complex and high-dimensional data collected in the sciences. This includes latent factor, dimensionality reduction, nonparametric and machine learning methodology. Primary areas of application include neurosciences and brain network modeling, environmental health, ecology, and human fertility among others. He is a fellow of the ASA, IMS and ISBA and has won numerous awards, including most notably the 2010 COPSS President’s Award. His work is very widely cited and he has an H-index over 70 on Google Scholar. Best regards, Giacomo Zanella

Seminar Guindani @Bocconi
by Giacomo Zanella 06 Sep '19

06 Sep '19

We are glad to announce the first DEC Statistics Seminar of the Fall 2019 series: Thursday, September 12 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Michele Guindani (University of California, Irvine) Title: Bayesian Approaches to Dynamic Model Selection Abstract: In many applications, investigators monitor processes that vary in space and time, with the goal of identifying temporally persistent and spatially localized departures from a baseline or ``normal" behavior. In this talk, I will first discuss a principled Bayesian approach for estimating time-varying functional connectivity networks from brain fMRI data. Dynamic functional connectivity, i.e., the study of how interactions among brain regions change dynamically over the course of an fMRI experiment, has recently received wide interest in the neuroimaging literature. Our method utilizes a hidden Markov model for classification of latent neurological states, achieving an estimation of the connectivity networks in an integrated framework that borrows strength over the entire time course of the experiment. Furthermore, we assume that the graph structures, which define the connectivity states at each time point, are related within a super-graph, to encourage the selection of the same edges among related graphs. Then, I will propose a Bayesian nonparametric model selection approach with an application to the monitoring of pneumonia and influenza (P&I) mortality, to detect influenza outbreaks in the continental United States. More specifically, we introduce a zero-inflated conditionally identically distributed species sampling prior which allows borrowing information across time and to assign data to clusters associated to either a null or an alternate process. Spatial dependences are accounted for by means of a Markov random field prior, which allows informing the selection based on inferences conducted at nearby locations. We show how the proposed modeling framework performs in an application to the P&I mortality data and in a simulation study and compare with common threshold methods for detecting outbreaks over time, with more recent Markov switching based models, and with other Bayesian nonparametric priors that do not take into account spatio-temporal dependence. Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to arianna.colombo(a)unibocconi.it *************************************************** Giacomo Zanella Assistant Professor - Statistics DEC - Department of Decision Sciences Bocconi University

Fwd: Ph.D. position in “Big data techniques for maintenance decision making under uncertainty” at TU/e
by Antonio DI CRESCENZO 03 Sep '19

03 Sep '19

---------- Messaggio inoltrato --------- Da: Kapodistria, S. <S.Kapodistria(a)tue.nl> Data: mar 3 set 2019 alle 13:36 Oggetto: Ph.D. position in “Big data techniques for maintenance decision making under uncertainty” at TU/e A: CC: Kapodistria, S. <S.Kapodistria(a)tue.nl> Dear colleagues, can you please distribute to your network the following PhD position advertisement? Thank you very much in advance. Best regards, Stella ———————————————————————————— Stella Kapodistria Department of Mathematics and Computer Science, Eindhoven University of Technology Postal address: P.O. Box 513, 5600 MB, Eindhoven, The Netherlands A PhD position in “Big data techniques for maintenance decision making under uncertainty” is available at Eindhoven University of Technology. For more information, see below. In the framework of the national NWA-ORC project “PrimaVera: Predictive maintenance for Very effective asset management <https://www.tue.nl/en/news/news-overview/primavera-predictive-maintenance-f…>”, there is a PhD position available in the Stochastics Section within the Department of Mathematics and Computer Science in Eindhoven University of Technology, in The Netherlands. The PrimaVera consortium, led by Twente University, consists of several Dutch higher education institutes and companies. Just-in-time maintenance requires a very accurate, enhanced physically based data-driven assessment of the system’s health and its future evolution guaranteeing the reliability, availability and affordability of the system through accurate monitoring, prognostics and diagnostics. This is organized around the following key game changers: • *Development of a big data health index*. Intelligent systems are equipped with sensors collecting data real-time. Analyzing the collected data can guarantee the reliability, availability and affordability of the system through accurate monitoring, prognostics and diagnostics. However, when dealing with especially large and complex systems, a key challenge for engineers is how to assess the present condition. By measuring the dynamics of the asset/network, modelling the dynamic behavior and by combining the real-time information, we aim to assess the present condition in the form of a health index and predict the remaining useful life (based on an assumed usage profile) using big data analytic techniques stemming from machine learning and artificial intelligence. • *Causal discovery of failures and root cause analysis.* A key step in failure prevention is to understand why systems fail. Data-driven techniques are good at finding correlations between failure modes, but finding causal relations is challenging. Combinations with physical models and domain knowledge will create crucial actionable insight and condition assessment. These associations will be incorporated in a dynamic estimation and inference paradigm framework for extracting causal graph dynamics, which can be efficiently queried to find the root causes of specific failures. • *Model-enhanced big data techniques for decision making under uncertainty*. To cope with the complex reality, we need hybrid approaches leveraging the advantages of statistical methods (guaranteed performance and uncertainty bounds), data mining approaches (superior in situations where rules are not yet known), and physics of failure models (causality). We propose to combine big data analytic techniques stemming from machine learning and artificial intelligence with the more classical decision-making approaches (stochastic dynamic programming, Markov decision models). This combination goes in two directions: (i) on the one hand, we propose to use big data analytics to automatically learn the health index model and other relevant failure models with the objective of optimally fitting the decision objective instead of the classical data fitting objective. (ii) On the other hand, we propose to use decision-making approaches to improve the data analytic techniques, e.g., by incorporating an exploration vs exploitation approach in the maintenance decision making to cope with the uncertainty in the information. *Job description* The project is methodologically oriented. It is on the interface of statistical operations research and machine learning, and it is strongly inspired by industrial challenges. The PhD project will be conducted in an international team and in close collaboration with academic and industrial partners of PrimaVera. The main goal of the PhD project is to develop mathematical tools/models/algorithms for (some of) the above-mentioned key game changers, and thus get a deeper insight. The research will be concluded with a PhD thesis. A small teaching load is part of the job. *Job requirements *Preference will be given to candidates in any branch of applied mathematics and to candidates from a different background (e.g. engineering) but with strong mathematical foundation.
