The method involves tracking the birth and death of topological features as one varies a tuning parameter. Features with short lifetimes are informally considered to be \u201ctopological noise.\u201d I am interested in bringing statistical ideas to persistent homology in order to distinguish topological signal from topological noise and to derive meaningful, yet computable, summaries of large datasets.\u0026nbsp; In this talk, I will define some of the existing topological summaries of data, and show how we can provide statistical guarantees of these summaries.\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.fasy.us\u0022 target=\u0022_blank\u0022\u003Ewww.fasy.us\u003C\/a\u003E\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Providing Statistical Guarantees for Topological Summaries of Data"}],"uid":"27466","created_gmt":"2014-11-25 19:04:53","changed_gmt":"2017-04-13 21:21:01","author":"Dani Denton","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2014-12-08T12:00:00-05:00","event_time_end":"2014-12-08T12:00:00-05:00","event_time_end_last":"2014-12-08T12:00:00-05:00","gmt_time_start":"2014-12-08 17:00:00","gmt_time_end":"2014-12-08 17:00:00","gmt_time_end_last":"2014-12-08 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"350171":{"id":"350171","type":"image","title":"Brittany Terese Fasy","body":null,"created":"1449245702","gmt_created":"2015-12-04 16:15:02","changed":"1475895075","gmt_changed":"2016-10-08 02:51:15","alt":"Brittany Terese Fasy","file":{"fid":"201081","name":"brittany-fasy.jpg","image_path":"\/sites\/default\/files\/images\/brittany-fasy_0.jpg","image_full_path":"http:\/\/tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/brittany-fasy_0.jpg","mime":"image\/jpeg","size":117529,"path_740":"http:\/\/tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/brittany-fasy_0.jpg?itok=BSz8iqFd"}}},"media_ids":["350171"],"groups":[{"id":"47223","name":"College of Computing"},{"id":"50875","name":"School of Computer Science"},{"id":"70263","name":"ARC"}],"categories":[],"keywords":[{"id":"5660","name":"algorithms"},{"id":"438","name":"data"},{"id":"111251","name":"Guarantees"},{"id":"4584","name":"randomness"},{"id":"168002","name":"Statistical"},{"id":"111261","name":"Topological"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1789","name":"Conference\/Symposium"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EDani Denton\u003Cbr \/\u003E\u003Ca href=\u0022mailto:denton@cc.gatech.edu\u0022\u003Edenton@cc.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
