This talk explores ways to use sketching so as to improve the scalability of algorithms for diverse classes of optimization problems and applications, from linear to nonlinear, local to global, derivative-based to derivative-free. Regression problems and Gauss-Newton techniques will receive particular attention. Numerical illustrations on standard optimization test problems as well as on some machine learning set-ups will be presented.<\/p>\n<p><em>Please note that the meeting URL for this event can be seen on the <\/em><a href=\"https:\/\/wordpress.cels.anl.gov\/cels-seminars\/event\/virtual-lans-seminar-12\/\">cels-seminars website<\/a><em>, which requires an Argonne login.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Seminar Title: Dimensionality Reduction Techniques for Large-Scale Optimization Problems Speaker: Coralia Cartis, Professor, Oxford University Date\/Time: September 30, 2020 \/ 10:30 AM &#8211; 11:30 AM Location: See meeting URL on the cels-seminars website (requires Argonne login) Description: Known by many &hellip; <a href=\"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/event\/virtual-lans-seminar-14\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":43,"featured_media":0,"template":"","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_tribe_events_status":"","_tribe_events_status_reason":"","footnotes":"","_members_access_role":[],"_members_access_error":""},"tags":[],"tribe_events_cat":[2],"class_list":["post-2664","tribe_events","type-tribe_events","status-publish","hentry","tribe_events_cat-seminar","cat_seminar"],"acf":[],"_links":{"self":[{"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tribe_events\/2664","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tribe_events"}],"about":[{"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/types\/tribe_events"}],"author":[{"embeddable":true,"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/users\/43"}],"version-history":[{"count":1,"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tribe_events\/2664\/revisions"}],"predecessor-version":[{"id":2665,"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tribe_events\/2664\/revisions\/2665"}],"wp:attachment":[{"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/media?parent=2664"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tags?post=2664"},{"taxonomy":"tribe_events_cat","embeddable":true,"href":"https:\/\/wordpress.cels.anl.gov\/lans-seminars\/wp-json\/wp\/v2\/tribe_events_cat?post=2664"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
