I will present a normal\u2013tangent decomposition of the conditional score that separates the effect of the observed constraints from the remaining uncertainty in the distribution. This decomposition provides a way to characterize the discrepancy between the unconditional and conditional diffusion dynamics, and to relate this discrepancy to information-theoretic quantities.\n\nBased on this perspective, I will introduce a sampling method that combines projected Langevin initialization on the constraint set with guided reverse diffusion. I will discuss theoretical and information-theoretic guarantees for the resulting sampler, as well as numerical results illustrating its behavior on linear inverse problems. At the end, I will also briefly discuss related results showing how the information content and structural properties of a target distribution can reduce the dependence of diffusion sampling on the ambient dimension.", "occurrence_notes":null, "guid":"150579-21909651@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/150579", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"1360", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Financial\/Actuarial Mathematics Seminar - Department of Mathematics", "group_id":"4890", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21909651 } , "150494-21909516": { "datetime_modified":"20260820T071619", "datetime_start":"20260902T163000", "datetime_end":"20260902T183000", "has_end_time":1, "date_start":"2026-09-02", "date_end":"2026-09-02", "time_start":"16:30:00", "time_end":"18:30:00", "time_zone":"America\/Detroit", "event_title":"A Counter-Constitutional Revolution: Donald Trump and the Rule of Law", "occurrence_title":"", "combined_title":"A Counter-Constitutional Revolution: Donald Trump and the Rule of Law: Annual Law & Ethics Lecture with Professor Kim Scheppele", "event_subtitle":"Annual Law & Ethics Lecture with Professor Kim Scheppele", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"Please join us as Professor Kim Scheppele delivers the 2026 Law & Ethics Lecture, co-sponsored by the University of Michigan Law School and the U-M Department of Philosophy. \n\nSince Donald Trump returned to the presidency, his administration has operated with lightning speed to upend many certainties of law and politics. How can we understand these changes? In this lecture, Prof. Scheppele will argue that we need to deconstruct attacks on the rule of law into different streams, each run by different people with different legal logics. Some policies stretch preexisting law in unrecognizable ways, while other policies seek to destroy law without replacement. Some policies enforce the law selectively, putting the president and his inner circle above the law even as they subject others to harsh enforcement of that same law. In perhaps the most revolutionary aspect of the Trump presidency, some within his administration have launched a counter-constitutional revolution to remake the US Constitution as we knew it, replacing the prior system of checks and balances with a super-presidency, thus destroying democracy by law. By disentangling these different strands, we can see that Trump is not a \u201che\u201d but a \u201cthey.\u201d Given the multiplicity of attacks on the rule of law, we may need a multipronged effort to restore the rule of law when the Trump era is over.", "occurrence_notes":null, "guid":"150494-21909516@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/150494", "building_id":"0", "building_name":"Jeffries Hall", "campus_maps_id":"637", "room":"1225", "location_name":"Jeffries Hall", "has_livestream":0, "cost":"", "tags":["Lecture","Discussion","Faculty","Free","Graduate","Graduate School","Graduate Students","History","Humanities","In Person","Law","Philosophy","Politics","Pre-Law","Public Policy","Research","Scholarship","Social Impact","Social Justice","Social Sciences","Talk","Activism"], "website":"https:\/\/michigan.law.umich.edu\/events-calendar", "sponsors":[ { "group_name":"University of Michigan Law School", "group_id":"3148", "website":"http:\/\/www.law.umich.edu" }, { "group_name":"Department of Philosophy", "group_id":"3186", "website":"http:\/\/www.lsa.umich.edu\/philosophy" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21909516 } , "102102-21910748": { "datetime_modified":"20260829T022109", "datetime_start":"20260902T170000", "datetime_end":"20260902T190000", "has_end_time":1, "date_start":"2026-09-02", "date_end":"2026-09-02", "time_start":"17:00:00", "time_end":"19:00:00", "time_zone":"America\/Detroit", "event_title":"Maize & Blue Cupboard Volunteering", "occurrence_title":"MBC Operating Hours", "combined_title":"Maize & Blue Cupboard Volunteering: Multiple conference events and sessions: MBC Operating Hours", "event_subtitle":"Multiple conference events and sessions", "event_type":"Conference \/ Symposium", "event_type_id":"5", "description":"Come help us during normal operating hours; as well as, unload our weekly Food Gatherers deliveries and stock our shelves!\u00a0If you are outside the U-M community, please reach out to maize.blue.cupboard@umich.edu to sign up.", "occurrence_notes":null, "guid":"102102-21910748@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/102102", "building_id":"", "building_name":"", "campus_maps_id":"", "room":"", "location_name":"Maize and Blue Cupboard inside Betsy Barbour", "has_livestream":0, "cost":"", "tags":["Sessions"], "website":"https:\/\/sessions.studentlife.umich.edu\/p\/track\/3152", "sponsors":[ { "group_name":"Sessions @ Michigan", "group_id":"4791", "website":"https:\/\/sessions.studentlife.umich.edu\/" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":35, "first_occurrence":21906688 } , "149925-21907378": { "datetime_modified":"20260829T003208", "datetime_start":"20260902T170000", "datetime_end":"20260902T180000", "has_end_time":1, "date_start":"2026-09-02", "date_end":"2026-09-02", "time_start":"17:00:00", "time_end":"18:00:00", "time_zone":"America\/Detroit", "event_title":"Ready, Set, Intern! for First Year Students", "occurrence_title":"", "combined_title":"Ready, Set, Intern! for First Year Students", "event_subtitle":"", "event_type":"Careers \/ Jobs", "event_type_id":"2", "description":"Navigating when and how to land an internship\u2014or knowing what you should even be doing in your first year\u2014can feel a little overwhelming.
