However, existing analyses of the algorithm for strongly log-concave distributions suggest that, as the dimension $d$ of the problem increases, the number of iterations required to ensure convergence within a desired error in the $W_2$ metric scales in proportion to $d$ or $\\sqrt{d}$. In this work, we argue that, despite this poor scaling of the $W_2$ error for the full set of variables, the behavior for a \\emph{small number} of variables can be significantly better: a number of iterations proportional to $K$, up to logarithmic terms in $d$, often suffices for the algorithm to converge to within a desired $W_2$ error for all $K$-marginals. We refer to this effect as \\textit{delocalization of bias}. We show that the delocalization effect does not hold universally and prove its validity for Gaussian distributions and strongly log-concave distributions with certain sparse interactions. Our analysis relies on a novel $W_{2,\\ell^\\infty}$ metric to measure convergence. A key technical challenge we address is the lack of a one-step contraction property in this metric. Finally, we use asymptotic arguments to explore potential generalizations of the delocalization effect beyond the Gaussian and sparse interactions setting.", "occurrence_notes":null, "guid":"130777-21866873@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/130777", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"EH4448", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"https:\/\/sites.google.com\/view\/probsemumich\/future-talks", "sponsors":[ { "group_name":"Probability and Analysis Seminar - Department of Mathematics", "group_id":"5203", "website":"https:\/\/sites.google.com\/view\/probsemumich\/future-talks" }, { "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":21866873 } }
