The tests are assumed to accept pools of individuals rather than just single individuals, with a test returning a positive result iff at least one individual in the pool is actually infected. Mathematically we ask for information-theoretic lower bounds showing that a certain number of tests is necessary to correctly learn the set of infected individuals as well as algorithmic upper bounds showing that a certain number of tests suffice. In this talk I am going to present some mathematical results, some experimental results and some open problems.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E----------------------------------\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Ca href=\u0022https:\/\/simons.berkeley.edu\/people\/amin-coja-oghlan\u0022\u003ESpeaker\u0026#39;s Webpage\u003C\/a\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cem\u003EVideos of recent talks are available at: \u003C\/em\u003E\u003Ca href=\u0022http:\/\/arc.gatech.edu\/node\/121\u0022\u003Ehttp:\/\/arc.gatech.edu\/node\/121\u003C\/a\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Ca href=\u0022https:\/\/mailman.cc.gatech.edu\/mailman\/listinfo\/arc-colloq\u0022\u003EClick here to subscribe to the seminar email list: arc-colloq@Klauscc.gatech.edu \u003C\/a\u003E\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Group Testing - Virtual via Bluejeans at 11:00am"}],"uid":"27544","created_gmt":"2021-03-17 14:36:19","changed_gmt":"2021-03-17 14:36:19","author":"Francella Tonge","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-04-12T12:00:00-04:00","event_time_end":"2021-04-12T13:00:00-04:00","event_time_end_last":"2021-04-12T13:00:00-04:00","gmt_time_start":"2021-04-12 16:00:00","gmt_time_end":"2021-04-12 17:00:00","gmt_time_end_last":"2021-04-12 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"70263","name":"ARC"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"177814","name":"Postdoc"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
