Stats and ML Thematic seminar: Nikita Zhivotovskiy, Friday July 7, 15h00
by Tim van Erven 05 Jun '23

05 Jun '23

Dear all, On Friday July 7 we have Nikita Zhivotovskiy speaking in the Statistics and Machine Learning Thematic Seminar. Nikita will be visiting us July 3-7. He has done excellent work both in statistics and machine learning, so it is highly recommended to come meet him. *Nikita Zhivotovskiy *(UC Berkeley, Department of Statistics, https://sites.google.com/view/nikitazhivotovskiy/) *Friday July 7*, 15h00-16h00 In person, at the University of Amsterdam Location: Science Park 904, Room TBA *Sharper Risk Bounds for Statistical Aggregation *In this talk, we take a fresh look at the classical results in the theory of statistical aggregation, focusing on the transition from global complexity to a more manageable local one. The goal of aggregation is to combine several base predictors to achieve a prediction nearly as accurate as the best one. This flexible approach operates without any assumptions on the structure of the class or the nature of the target. Though aggregation is studied in both sequential and statistical settings, each with their unique differences, they both traditionally use the same "global" complexity measure. Our discussion will highlight the lesser-known PAC-Bayes localization method used in our proofs, allowing us to prove a localized version of a classical bound for the exponential weights estimator by Leung and Barron, and a deviation-optimal localized bound for the Q-aggregation estimator. Furthermore, we will explore the links between our work and ridge regression. Joint work with Jaouad Mourtada and Tomas Vaškevičius. * * Seminar organizers: Tim van Erven Botond Szabo https://mschauer.github.io/StructuresSeminar/ -- Tim van Erven<tim(a)timvanerven.nl> www.timvanerven.nl

June 7, 15:00 Machine Learning Theory Seminar++ Meeting with Odysseas Kanavetas
by Wouter Koolen-Wijkstra 31 May '23

31 May '23

Dear researchers, Centrum Wiskunde & Informatica (CWI) kindly invites you seventh Seminar++ meeting on Machine Learning Theory, taking place on Wednesday June 7 from 15:00 - 17:00. These Seminar++ meetings consist of a one-hour lecture building up to an open problem, followed by an hour of brainstorming time. The meeting is intended for interested researchers including PhD students. These meetings are freely accessible without registration. Cookies, coffee and tea will be provided in the half-time break. The meeting of 7 June will be hosted by: Odysseas Kanavetas <https://www.universiteitleiden.nl/en/staffmembers/odysseas-kanavetas#tab-1> Assistant Professsor at the University of Leiden <https://www.universiteitleiden.nl/en>. Asymptotically optimal control for Markov Decision Processes (MDP) under side constraints *Abstract:* After a brief review of the multi-armed bandit (MAB) problem and its online machine learning applications, we present our work on the model with side constraints. The constraints represent circumstances in which bandit activations are restricted by the availability of certain resources that are replenished at a constant rate. Then, we consider the problem of adaptive control for Markov Decision Processes (MDP), under side constraints, when there is incomplete information for the transition probabilities and its rewards. Under suitable irreducibility assumptions for the MDP we establish a lower bound for the regret. An open problem is to construct adaptive policies that maximize the rate of convergence of realized rewards to that of the optimal (non adaptive) policy under complete information. We also discuss applications for queuing control problems and reliability models. The event takes place in room L016 in the CWI building, Science Park 123, Amsterdam. The Seminar++ Meetings are part of the Machine Learning Theory Semester Programme <https://www.cwi.nl/en/events/cwi-research-semester-programs/research-progra…>, which runs in Spring 2023.

May 24, 15:00 Machine Learning Theory Seminar++ Meeting with Sophie Langer

16 May '23

Dear researchers, Centrum Wiskunde & Informatica (CWI) kindly invites you sixth Seminar++ meeting on Machine Learning Theory, taking place on Wednesday May 24 from 15:00 - 17:00. These Seminar++ meetings consist of a one-hour lecture building up to an open problem, followed by an hour of brainstorming time. The meeting is intended for interested researchers including PhD students. These meetings are freely accessible without registration. Cookies, coffee and tea will be provided in the half-time break. The meeting of 24 May will be hosted by: Sophie Langer <https://sites.google.com/view/sophielanger/start> Assistant Professsor at the University of Twente <https://www.utwente.nl/en/> *Image classification: A (new) statistical viewpoint* *Abstract:* In this talk we consider a simple supervised classification problem for object recognition on grayscale images. There are two possible perspectives to solve this problem. Firstly, one can interpret object recognition as a high-dimensional classification problem, where every pixel is a variable. The task is then to map these pixel values to the conditional class probabilities or the labels. Increasing the dimension makes the problem considerably harder, leading to slow convergence rates due to the curse of dimensionality. Another perspective is to view images as two-dimensional objects. Increasing the number of pixels leads to higher resolution and therefore better performance is expected for large images. Following the second route, we present a new image deformation model, for which we propose and analyze two different classifiers. The first method estimates the image deformation by support alignment. Under a minimal separation condition, it is shown that perfect classification is possible. The second method fits a CNN to the data. We derive a rate for the misclassification error depending on the sample size and the number of pixels /d^2 /. Both classifiers are empirically compared on images generated from the MNIST handwritten digit database. The event takes place in room L016 in the CWI building, Science Park 123, Amsterdam. The Seminar++ Meetings are part of the Machine Learning Theory Semester Programme <https://www.cwi.nl/en/events/cwi-research-semester-programs/research-progra…>, which runs in Spring 2023.

May 10, 15:00 Machine Learning Theory Seminar++ Meeting with Rianne de Heide
by Wouter Koolen-Wijkstra 21 Apr '23

21 Apr '23

Dear researchers, Apologies for re-sending, this is to test a config update to prevent future email bounces. Centrum Wiskunde & Informatica (CWI) kindly invites you to the fifth Seminar++ meeting on Machine Learning Theory, taking place on Wednesday May 10 from 15:00 - 17:00. These Seminar++ meetings consist of a one-hour lecture building up to an open problem, followed by an hour of brainstorming time. The meeting is intended for interested researchers including PhD students. These meetings are freely accessible without registration. Cookies, coffee and tea will be provided in the half-time break. The meeting of 10 May will be hosted by: Rianne de Heide <https://riannedeheide.github.io/> (Assistant Professor at the Vrije Universiteit Amsterdam <https://vu.nl/>) *Multiple testing with e-values: overview and open problems* Abstract: Researchers in genomics and neuroimaging often perform hundreds of thousands of hypothesis tests simultaneously. The scale of these multiple hypothesis testing problems is enormous, and with extreme dimensionality comes extreme risk for false positives. The field of multiple testing addresses this problem in various ways. Recently, the new theory of hypothesis testing with e-values has been brought to the field of multiple testing. In this talk I will give an overview of the most important frameworks in multiple testing and recent developments in multiple testing with e-values. Finally, I will open the discussion for open problems in this area, focusing on FDP estimation and confidence with e-values. This will create a framework for fully interactive multiple testing. The event takes place in room L016 in the CWI building, Science Park 123, Amsterdam. The Seminar++ Meetings are part of the Machine Learning Theory Semester Programme <https://www.cwi.nl/en/events/cwi-research-semester-programs/research-progra…>, which runs in Spring 2023.
