We present AI-Descartes (generator-verifier paradigm), AI-Hilbert (unified hypothesis generation and testing), and AI-Noether (algebraic-geometric theory revision via abductive reasoning) as transformative approaches to mathematical model discovery. These frameworks advocate for conceptual evolution of the scientific method toward deeper AI integration in pursuing both interpretable and universal models.\r\n\r\nWednesday, September 10, 4 pm, East Hall 1360: Matrix-Mimetic Tensor Algebra: Optimal Decompositions and Equivariant Learning\r\nThis lecture introduces a novel tensor-tensor algebra that preserves essential matrix-algebraic properties while overcoming limitations of conventional tensorial frameworks, culminating in an Eckart-Young-like theorem that resolves a decades-long open problem in tensor analysis. We demonstrate how this framework enables seamless retrofitting of existing computational workflows (Hamiltonian neural networks, tensor Graph Convolutional Networks) and extends to tensor group symmetry theory for equivariant learning applications. This work opens pathways to new tensorial algebras that can reveal deeper patterns in high-dimensional information previously inaccessible to traditional methods.\r\n\r\nThursday, September 11, 4 pm, East Hall 4448: From Big Data to Right Data: Information-Theoretic Optimal Experimental Design\r\nThis lecture addresses the modern paradox where unprecedented data accumulation capabilities make selective identification of informative samples more critical than ever for meaningful model development. We review theoretical foundations of experimental design within inverse problems frameworks, examining strategies for well-posed and ill-posed settings while establishing approaches for design preferences, budget allocation, and risk assessment. Through information-theoretic principles, we demonstrate how optimal experimental design creates a paradigm shift from data volume to information content, with transformative implications for resource-constrained scientific methodology.\r\n\r\nDr. Lior Horesh is a Principal Research Scientist, Master Inventor and a Senior Manager of the \u200eMathematics & Theoretical Computer Science (formerly Mathematics of AI) department at IBM Research.

Our focal system for this work involves natural populations of Plantago host plants and their powdery mildew pathogens. We use observational, experimental, and theoretical approaches to study these plant-fungus interactions along a large latitudinal gradient (spanning from southern Louisiana to northern Minnesota) and across an urbanization gradient in St. Louis, Missouri. Key research questions we have recently asked include: How does climate shape the geographic distribution and seasonality of powdery mildew on Plantago around the world? Are powdery mildew strains locally adapted to temperature or to host genotypes along a latitudinal gradient? In what geographic regions and seasons can powdery mildew undergo sexual reproduction? How do powdery mildew dynamics vary within and between host populations across a gradient of urbanization? Why are there larger powdery mildew epidemics in more urban populations? Our answers to these questions fill critical gaps in understanding wild plant-pathogen interactions in an increasingly warm and urbanized world.", "occurrence_notes":null, "guid":"137278-21880018@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/137278", "building_id":"1005169", "building_name":"Biological Sciences Building", "campus_maps_id":"631", "room":"1060", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["Biology","Ecology And Evolutionary Biology","seminar","Workshop"], "website":"https:\/\/penczykowskilab.com\/", "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Thursday Seminars", "group_id":"3822", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/08\/event_137278_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2025\/08\/event_137278_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/08\/event_137278_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/08\/event_137278_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/08\/event_137278_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/08\/event_137278_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/08\/event_137278_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/08\/event_137278_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2025\/08\/event_137278_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/08\/event_137278_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2025\/08\/event_137278_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/08\/event_137278_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/08\/event_137278_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/08\/event_137278_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/08\/event_137278_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2025\/08\/event_137278_original-1.png" }, "occurrence_count":1, "first_occurrence":21880018 } }
