However, existing algorithms could suffer from insufficient sample size under optimal treatments, especially for chronic diseases involving long stages of decision-making. To address these challenges, we propose a novel individualized learning method which estimates the DTR with a focus on prioritizing alignment between the observed treatment trajectory and the one obtained by the optimal regime across decision stages. By relaxing the restriction that the observed trajectory must be fully aligned with the optimal treatments, our approach substantially improves the sample efficiency and stability of inverse probability weighted based methods. In particular, the proposed learning scheme builds a more general framework which includes the popular outcome weighted learning framework as a special case of ours. Moreover, we introduce the notion of stage importance scores along with an attention mechanism to explicitly account for heterogeneity among decision stages. We establish the theoretical properties of the proposed approach, including the Fisher consistency and finite-sample performance bound. Empirically, we evaluate the proposed method in extensive simulated environments and a real case study for COVID-19 pandemic.\r\n\r\n\r\nhttps:\/\/faculty.sites.uci.edu\/qulab\/", "occurrence_notes":null, "guid":"132382-21870849@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/132382", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"340", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["seminar"], "website":"https:\/\/lsa.umich.edu\/stats", "sponsors":[ { "group_name":"Department of Statistics", "group_id":"3473", "website":"" }, { "group_name":"Department of Statistics Seminar Series", "group_id":"3585", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/02\/event_132382_original-1.jpeg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2025\/02\/crop-event_132382_original-1.jpeg" }, "occurrence_count":1, "first_occurrence":21870849 } , "84303-21621543": { "datetime_modified":"20240130T121551", "datetime_start":"20250314T100000", "datetime_end":"20250314T200000", "has_end_time":1, "date_start":"2025-03-14", "date_end":"2025-03-14", "time_start":"10:00:00", "time_end":"20:00:00", "time_zone":"America\/Detroit", "event_title":"Unsettling Histories: Legacies of Slavery and Colonialism", "occurrence_title":"", "combined_title":"Unsettling Histories: Legacies of Slavery and Colonialism", "event_subtitle":"", "event_type":"Exhibition", "event_type_id":"7", "description":"Organized as a response to the Museum\u2019s recent acquisition of Titus Kaphar\u2019s Flay (James Madison), this upcoming reinstallation of one of our most prominent gallery spaces forces us to grapple with our collection of European and American art, 1650-1850.\n \nIn recent times, growing public awareness of the continued reverberations of the legacy of slavery and colonization has challenged museums to examine the uncomfortable histories contained in our collections, and challenged the public to probe the choices we make about those stories. Choices about which artists you see in our galleries, choices about what relevant facts we share about the works, and choices about what - out of an infinite number of options - we don\u2019t say about them.\n \nPieces in this exhibition were made at a time when the world came to be shaped by the ideologies of colonial expansion and Western domination. And yet, that history and the stories of those marginalized do not readily appear in the still lives and portraits on display here. By grappling with what is visible and what remains hidden, we are forced to examine whose stories and histories are prioritized and why.\u00a0\u00a0\n \nIn this online exhibition, you can explore our efforts to deeply question the Museum\u2019s collection and our own past complicity in favoring colonial voices. In the Museum gallery, which will open in early 2021, you\u2019ll be able to experience the changes we\u2019re making to the physical space to highlight a more honest version of European and American history.\u00a0\n \nBy challenging our own practice, and continuing to add to what we know and what we write about the works we display, UMMA tells a more complex and more complete story of this nation - one that unsettles, and fails to settle for, simple narratives.\u00a0\n \n\u201cInvisible things are not necessarily \u2018not there\u2019.... Certain absences are so stressed, so ornate, so planned, they call attention to themselves; arrest us with intentionality and purpose, like neighborhoods that are defined by the population held away from them.\u201d\u00a0\n \n\u2014 Toni Morrison\n\nLead support for Unsettling Histories: Legacies of Slavery and Colonialism\u00a0is provided by the University of Michigan Office of the Provost,\u00a0the U-M Arts Initiative, and the Susan and Richard Gutow Endowed Fund.\n\u00a0", "occurrence_notes":null, "guid":"84303-21621543@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/84303", "building_id":"1000151", "building_name":"Museum of Art", "campus_maps_id":"11", "room":"European and American Decorative Art", "location_name":"Museum of Art", "has_livestream":0, "cost":"", "tags":["History","UMMA","Museum","Art","Exhibition","European"], "website":"https:\/\/www.facebook.com\/ummamuseum\/", "sponsors":[ { "group_name":"University of Michigan Museum of Art (UMMA)", "group_id":"1177", "website":"http:\/\/www.umma.umich.edu\/" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2022\/08\/event_84303_original-5.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2022\/08\/event_84303_original-5.jpg" }, "occurrence_count":470, "first_occurrence":21621195 } }
