October 10 seminars on data driven control
by Anders Rantzer 04 Oct '24

04 Oct '24

Dear all, As previously announced at the information coffee, Olle's dissertation on October 11 will be preceded by a seminar series in the afternoon of October 10. See below. Welcome! /Anders ---------------------------------------------------------------------- October 10 at 13:15-14:00 in the Seminar Room M:3170-73 in the M-building, LTH. Jack Umenberger, Oxford University Title: No such thing as a model-free lunch? Model-free search and reliable decision making. Abstract: Inspired by breakthrough results in the processing of complex data, machine learning is being increasingly applied to problems in decision-making and control. However, to be suitable for deployment in applications, we require learning-based algorithms that come with guarantees of reliability, robustness, and safety. This talk will focus on the reliability of model-free policy search, addressing the question: when do such methods find optimal solutions, and when do they get trapped in poor local minima? Existing work has considered static policies; however, for dynamic policies that remember past observations - necessary for optimal decision making in many applications - these questions have hitherto remained unanswered. Focusing on the classic control-theoretic problem of output estimation, I will present the first model-free policy search algorithm for dynamic policies guaranteed to converge to the optimal solution. Along the way, I’ll also describe my path toward working on this problem, highlighting some of my contributions to model-based approaches for safe and reliable control, including data-driven robust control, system identification, and trajectory optimization. I will offer my perspective on the strengths and weaknesses of model-free and model-based methods, as well as the ways in which they complement each other. ---------------------------------------------------------------------- October 10 at 14:05-14:50 Håkan Hjalmarsson, KTH Title: Data-driven control: A statistical decision theory perspective There are many different methods for deriving a controller from a given data.set but little guidance is provided in the literature in terms of which methods are preferrable from a performance point of view. In this talk we focus on the information aspects of the problem. We use existing results from decision theory to establish necessary and sufficient conditions for a data-driven controller that guarantees that there is no other data-driven controller that uniformly (regardless of the underlying system) can outperform it in terms of average control cost. We discuss issues like direct vs indirect data-driven control from this perspective. ---------------------------------------------------------------------- October 10 at 15:30-16:15 Valentina Breschi, TU Eindhoven Title: Philosophies, promises and challenges of direct data-driven control Abstract: Direct data-driven control (DDC) has become a central focus in control research, advocating the direct use of data to achieve desired control objectives and, eventually, satisfy design constraints. By exploring a selected set of DDC techniques, this talk provides a (personal) take on the philosophy behind data-driven control, highlighting some of the promises that DDC approaches have already fulfilled and spotlighting some of the challenges yet to be faced. Bio: Valentina Breschi received her B.Sc. in Electronic and Telecommunication Engineering and her M.Sc. in Electrical and Automation Engineering from the University of Florence (Italy) in 2011 and 2014, respectively. She received her Ph.D. in Control Systems from IMT School for Advanced Studies Lucca (Italy) in 2018. From January to July 2017, she was a visiting scholar at the Department of Aerospace Engineering, University of Michigan (United States). From 2018 to 2020, she was a post-doctoral researcher at Politecnico di Milano (Italy), where she then held a fixed-term position as a junior Assistant Professor from 2020 to 2023. In 2023, she joined the Department of Electrical Engineering at Eindhoven University of Technology (The Netherlands) as an Assistant Professor. Her main research interests include data-driven control, system identification, with a focus on piecewise affine and switching systems, collaborative learning, and human-centered policy design, focusing on mobility systems. ---------------------------------------------------------------------- October 10 at 16:20-17:05 Babak Hassibi, Caltech Title: Distributionally Robust Control Abstract: Traditional methods in control either assume that the disturbances are random processes with known statistics (stochastic or H_2 control) or that they are adversarial (robust or H_infinity control). Recently, there has been growing interest in a framework, called distributional robustness, that can interpolate between these two extremes. In distributionally robust control one assumes that the disturbances have a distribution that lies in a given uncertainty set and the goal is to design a controller that minimizes the worst case expected control cost over all distributions in this set. A not-very-well-known fact is that, if the uncertainty set is a Kullback-Liebler ball around a nominal Gaussian distribution, then distributionally-optimal controllers are given by central H_infinity controllers. These days Wasserstein-2 balls are mostly considered for distributional robustness because, unlike KL divergence, they do not require the support of all the distributions within the ball to be identical, and because of their connections to optimal transport theory. In this talk we consider the problem of designing distributionally robust optimal (DRO) controllers in the Wasserstien-2 metric. We characterize the optimal control policy and show that, although it lacks a finite-order state-space realization (i.e., it is non-rational), it can be characterized by a finite-dimensional parameter. Leveraging this, we develop an efficient frequency-domain algorithm to compute the optimal control policy and present a convex optimization method to construct a rational state-space controller that best approximates the optimal non-rational controller in the H_infinity norm. This approach leads to efficiently computable control strategies and we demonstrate its advantages over conventional H_2 and H_infinity control through several examples.

This is a total variation-regularized least squares problem which is usually solved using first-order iterative minimization algorithms, e.g. ISTA or FISTA. These methods all require as input an appropriate step length. This step length is related to the Lipschitz constant for the gradient of the quadratic loss function, and equals the square of the largest singular value of the measurement map. In applications, this number is usually computed directly as the largest eigenvalue of a huge square matrix - a compuation that sometimes becomes a bottleneck in an otherwise optimized algorithm. We have effectively eliminate this bottleneck for CASSI reconstructions by showing how the Lipschitz constant can be calculated from a square matrix whose size is easily three orders of magnitudes smaller than in the direct approach. ** *Upcoming breakfast seminar* The breakfast seminars are scheduled once per month with the main purpose of triggering multi-disciplinary discussions and potential collaborations. These are the upcoming planned slots: * *Nov 5*, 09:00-10:00 @ Control * *Dec 3*, 09:00-10:00 @ Math Speaker and registration details will be sent out closer to each slot. Welcome!

Reminder - please check you vacationdays
by Cecilia Edelborg 27 Sep '24

27 Sep '24

Dear all, This is a kind reminder, you can always ask Eva or me if you have any questions. All employees are entitled to at least 25 days of annual leave per year, but as a public sector employee, through collective agreements, you have more than 25 days of annual leave as well as being entitled to paid annual leave as of your first year of employment, as the annual leave year coincides with the calendar year. In order to take out full paid annual leave, you must have been employed for the whole year. Remember that you can only take leave for whole days. The number of days of annual leave you have is determined by your age: * 28 days up to and including the year you turn 29. * 31 days from the year you turn 30. * 35 days from the year you turn 40. The year’s entire annual leave is primarily to be used during the year in question, but if you are entitled to more than 20 days of paid leave, you may choose to save one or several of the additional days for a subsequent calendar year. You must always use at least 20 days out of the year’s quota of leave during the year in question. The aim of allowing employees to save days of annual leave is to enable them to take a longer period of leave in a subsequent year. At most, you can save 30 days of leave. If you wish to take saved days of annual leave in connection with your main holiday, you are to apply for this when planning annual leave for the year. Sincerely and have a nice weekend😊 Cecilia Vänliga hälsningar/ Best regards Cecilia Edelborg Financial and HR Administrator [cid:image001.png@01DB1024.F85B9460] _______________________________________ Institutionen för Reglerteknik/ Department of Automatic Control Box 118, SE-221 00 LUND, Sweden Visiting address: Ole Römersväg 1 Phone: 046 -222 87 79/Int: +46 46 222 87 79 Mobile: 0707-52 63 22 E-mail: cecilia.edelborg(a)control.lth.se<mailto:cecilia.edelborg@control.lth.se> Confidentiality Notice: This message is confidential.
