The explainability framework (based on gradient SHAP) is applied to each grid point in the domain, and through percolation analysis we identify coherent flow regions of high importance. These regions have around 70% overlap with the intense Reynolds-stress (Q) events in two-dimensional vertical planes. Interestingly, these importance-based structures have high overlap with classical turbulence structures (Q events, streaks and vortex clusters) in different wall-normal locations, suggesting that this new framework provides a more comprehensive way to study turbulence. We also discuss the application of deep reinforcement learning (DRL) to discover active-flow-control strategies for turbulent flows, including turbulent channels, three-dimensional cylinders and turbulent separation bubbles. In all the cases, the discovered DRL-based strategies significantly outperform classical flow-control approaches. We conclude that DRL has tremendous potential for drag reduction in a wide range of complex turbulent-flow configurations.\r\n\r\nBio: Dr. Ricardo Vinuesa is joining the Department of Aerospace Engineering at the University of Michigan in the Fall of 2025.

The works on view in this exhibition, all brought into the Museum between 2019 and the present, shows how institutions like UMMA are becoming more permeable to societal challenges, and more nimble in responding to them in service to all in their communities. In this exhibition you will find works that reflect on how global migrations, race, gender, and ecological change shape the way we engage with the world and inform our visions for the future.\n \nThis collection of artistic engagements with issues give us tools to envision who we want to be as individuals, as a museum, and as a society, connected to one another across space and experience.\n \nSo gather here to take in these latest works of art brought here for you. Gather here to be engulfed in their forms and meanings, to discuss their takes, to learn, to disagree. Gather to relax, make a friend, drink a coffee, finish the daily Wordle.

You won\u2019t look at leaves the same way again! \r\n\r\nThis project is a collaboration between MBGNA and the Weber and Vasconcelos labs in the Department of Ecology and Evolutionary Biology, led by PhD student Rosemary Glos.", "occurrence_notes":null, "guid":"130943-21867440@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/130943", "building_id":"0", "building_name":"Matthaei Botanical Gardens", "campus_maps_id":"554", "room":"", "location_name":"Matthaei Botanical Gardens", "has_livestream":0, "cost":"", "tags":["Biology","eeb","Family","Free","In Person","science"], "website":"https:\/\/mbgna.umich.edu\/event\/leaves-under-lens", "sponsors":[ { "group_name":"Matthaei Botanical Gardens & Nichols Arboretum", "group_id":"1072", "website":"" }, { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/01\/event_130943_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/01\/event_130943_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/01\/event_130943_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/01\/event_130943_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/01\/event_130943_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/01\/event_130943_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/01\/event_130943_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/01\/event_130943_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/01\/event_130943_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/01\/event_130943_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/01\/event_130943_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/01\/event_130943_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/01\/event_130943_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/01\/event_130943_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/01\/event_130943_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/01\/event_130943_original-1.png" }, "occurrence_count":72, "first_occurrence":21867427 } , "132381-21870848": { "datetime_modified":"20250211T093930", "datetime_start":"20250214T100000", "datetime_end":"20250214T110000", "has_end_time":1, "date_start":"2025-02-14", "date_end":"2025-02-14", "time_start":"10:00:00", "time_end":"11:00:00", "time_zone":"America\/Detroit", "event_title":"Statistics Department Seminar Series: Yixin Wang, Assistant Professor, Department of Statistics, University of Michigan.", "occurrence_title":"", "combined_title":"Statistics Department Seminar Series: Yixin Wang, Assistant Professor, Department of Statistics, University of Michigan.: \"Causal Inference for Unstructured Data\"", "event_subtitle":"\"Causal Inference for Unstructured Data\"", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Abstract: Causal inference traditionally relies on tabular data, where treatments, outcomes, and covariates are manually collected and labeled. However, many real-world problems involve unstructured data\u2014images, text, and videos\u2014where treatments or outcomes are high-dimensional and unstructured, or all causal variables are hidden within the unstructured observations. This talk explores causal inference in such settings.\r\n\r\nWe begin with cases where all causal variables (including treatments, outcomes, covariates) are hidden in unstructured observations. These causal problems require a crucial first step, extracting high-level latent causal factors from raw unstructured inputs. We develop algorithms to identify these factors. While traditional methods often assume statistical independence, causal factors are often correlated or causally connected. Our key observation is that, despite correlations, the causal connections (or the lack of) among factors leave geometric signatures in the latent factors' support - the ranges of values each can take. These signatures allow us to provably identify latent causal factors from passive observations, interventions, or multi-domain datasets (up to different transformations).\r\n\r\nNext, we tackle cases where unstructured data itself serves as either the treatment or the outcome. In these cases, standard causal queries like average treatment effect (ATE) are not suitable\u2014subtracting one text, image, or video outcome from another is meaningless. High-dimensional unstructured treatments also challenge the overlap assumption required for causal identification. To address these challenges, we propose new causal queries: for unstructured outcomes, we pinpoint outcome features most affected by the treatment; for unstructured treatments, we identify influential treatment features driving outcome differences. Finally, we extend these ideas to decision-making algorithms, such as optimizing natural language actions for desired outcomes.\r\n\r\nhttps:\/\/yixinwang.github.io\/", "occurrence_notes":null, "guid":"132381-21870848@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/132381", "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_132381_original-1.jpeg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/02\/crop-event_132381_original-1.jpeg" }, "occurrence_count":1, "first_occurrence":21870848 } }
