<p><strong>Abstract:</strong> A problem that has been of recent interest in statistical
inference, machine learning and signal processing is that of
understanding the asymptotic behavior of regularized least squares
solutions under random measurement matrices (or dictionaries). The Least
Absolute Shrinkage and Selection Operator (LASSO or least-squares with
l1 regularization) is perhaps one of the most interesting examples. In
this talk, we review precise expressions for the asymptotic performance
of such problems for a number of different cases, in particular when the
elements of the dictionary matrix are sampled independently from a
Gaussian distribution. We further mathematically confirm that these
expressions remain valid under a milder assumption of sub-Gaussian
matrices. In particular, we establish the universality of the asymptotic
statistics (e.g., the average quadratic risk) of LASSO with
non-Gaussian dictionaries.</p>https://www.chalmers.se/en/centres/chair/events/Pages/From-Philosophy-to-Ethics-to-Law-to-Technology-and-Back.aspxhttps://www.chalmers.se/en/centres/chair/events/Pages/From-Philosophy-to-Ethics-to-Law-to-Technology-and-Back.aspxFrom Philosophy to Ethics to Law to Technology and Back – Thoughts on Current European State Of The Art<p>EC, lecture hall, Hörsalsvägen 11, EDIT trappa C, D och H</p><p>Welcome to a seminar under the theme: AI ETHICS at Chalmers, with the speaker Gordana Dodig Crnkovic, Professor, Interaction Design division, Department of Computer Science and Engineering at Chalmers and the University of Gothenburg.</p>https://www.chalmers.se/en/departments/cse/calendar/Pages/Licentiate-Seminar-Claudio-Augustin-Mista.aspxhttps://www.chalmers.se/en/departments/cse/calendar/Pages/Licentiate-Seminar-Claudio-Augustin-Mista.aspxClaudio Augustín Mista, Computer Science and Engineering<p>EA, lecture hall, Hörsalsvägen 11, EDIT trappa C, D och H</p><p>DRAGEN: Automated Derivation of Random Generators for Algebraic Data Types</p>
