One area of functional trait ecology that remains understudied is temporal variation in functional traits, especially in understory forest communities, and its impact on functional diversity. I leveraged an experimental chronosequence at the University of Michigan Biological Station to investigate how functional traits of understory plants vary at three time scales - within the growing season, between two years, and along the chronosequence - and in coordination with environmental changes, species turnover, and intraspecific variation. This project calls attention to the temporal variability of plant communities that goes unnoticed in single time-point studies and highlights the use of chronosequences for studying community assembly.", "occurrence_notes":null, "guid":"121492-21846607@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/121492", "building_id":"1005169", "building_name":"Biological Sciences Building", "campus_maps_id":"631", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["Biology","AEM Featured","Biosciences","Bsbsigns","Ecology & Biology","Ecology And Evolutionary Biology","eeb","Herbarium","Museum - Herbarium","Museum - Zoology","Museum Of Zoology"], "website":"", "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"Program in Biology", "group_id":"3783", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" }, { "group_name":"Research Museums Center", "group_id":"4159", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2024\/04\/event_121492_original-1.jpeg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2024\/04\/crop-event_121492_original-1.jpeg" }, "occurrence_count":1, "first_occurrence":21846607 } , "121494-21846608": { "datetime_modified":"20240415T160400", "datetime_start":"20240425T150000", "datetime_end":"20240425T160000", "has_end_time":1, "date_start":"2024-04-25", "date_end":"2024-04-25", "time_start":"15:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"899 Seminar Series: Ashwin Pananjady", "occurrence_title":"", "combined_title":"899 Seminar Series: Ashwin Pananjady: Sharply predicting the behavior of complex iterative algorithms with random data", "event_subtitle":"Sharply predicting the behavior of complex iterative algorithms with random data", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"Presenter Bio:\r\nAshwin Pananjady is an Assistant Professor at Georgia Tech, with a joint appointment between the Schools of Industrial and Systems Engineering and Electrical and Computer Engineering. He received his PhD in Electrical Engineering and Computer Science from UC Berkeley and his BTech in Electrical Engineering from IIT Madras. His research interests lie in high dimensional statistics, optimization, signal processing, and information theory, and their applications to machine learning, reinforcement learning, and data science. Pananjady has received research awards from Adobe and Amazon, a Best Paper Prize (runner-up) for Young Researchers in Continuous Optimization from the Mathematical Optimization Society, the Lawrence D.

His teaching has been recognized at both UC Berkeley and Georgia Tech.\r\n\r\n\r\nAbstract:\r\nIterative algorithms are the workhorses of modern signal processing and statistical learning and are widely used to fit complex models to random data. While the choice of an algorithm and its hyperparameters determines both the speed and fidelity of the learning pipeline, it is common for this choice to be made heuristically, either by expensive trial-and-error or by comparing upper bounds on convergence rates of various candidate algorithms. Motivated by these issues, we develop a principled framework that produces sharp, iterate-by-iterate characterizations of solution quality for complex iterative algorithms on several nonconvex model-fitting problems with random data. Such sharp predictions can provide precise separations between families of algorithms while also revealing nonstandard convergence phenomena. We will showcase the general framework on several canonical models in statistical machine learning.", "occurrence_notes":null, "guid":"121494-21846608@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/121494", "building_id":"1000429", "building_name":"Industrial and Operations Engineering Building", "campus_maps_id":"73", "room":"2717", "location_name":"Industrial and Operations Engineering Building", "has_livestream":0, "cost":"", "tags":["899 Seminar Series","Industrial And Operations Engineering"], "website":"", "sponsors":[ { "group_name":"Industrial & Operations Engineering", "group_id":"3301", "website":"http:\/\/ioe.engin.umich.edu\/" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2024\/04\/event_121494_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2024\/04\/event_121494_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2024\/04\/event_121494_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2024\/04\/event_121494_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2024\/04\/event_121494_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2024\/04\/event_121494_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2024\/04\/event_121494_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2024\/04\/event_121494_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2024\/04\/event_121494_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2024\/04\/event_121494_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2024\/04\/event_121494_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2024\/04\/event_121494_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2024\/04\/event_121494_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2024\/04\/event_121494_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2024\/04\/event_121494_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2024\/04\/event_121494_original-1.png" }, "occurrence_count":1, "first_occurrence":21846608 } }
