However, designing VA systems for power users poses various challenges, such as addressing diversity in user expertise, metric selection, user modeling to automatically infer preferences, evaluating the success of these systems, etc. Through my research, I investigate how power users can communicate their preferences to interactively construct machine learning models in support of various data analytic goals.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ESpecifically, I explore and analyze several VA techniques such as multi-model steering, model selection, interactive objective functions, conflict resolution in objective functions etc. to\u0026nbsp;facilitate specification of user goals and objectives to underlying model(s) using VA systems.\u0026nbsp;In the end, I summarize my contribution(s) and then reflect on assumptions, strengths, and limitations of the research to inform potential future direction of this work.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EMS Teams Meeting Invitation\u003C\/strong\u003E\u003Cstrong\u003EMedium\u003C\/strong\u003E\u003Cstrong\u003E: (Via MS Teams on Chrome\/MS Edge browser or MS Teams App.)\u003C\/strong\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EMedium: (Via MS Teams on Chrome\/MS Edge browser or MS Teams App.)\u0026nbsp; \u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003E________________________________________________________________________________\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EMicrosoft Teams meeting\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EJoin on your computer or mobile app\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Ca href=\u0022https:\/\/teams.microsoft.com\/l\/meetup-join\/19%3ameeting_NTY0MzM4NDctNjE2OC00YmQ5LTlmNGYtYzc2NGU3ZjVlMzBj%40thread.v2\/0?context=%7b%22Tid%22%3a%22482198bb-ae7b-4b25-8b7a-6d7f32faa083%22%2c%22Oid%22%3a%2293ce84d0-7766-4111-980b-f193311ad802%22%7d\u0022 target=\u0022_blank\u0022 title=\u0022https:\/\/teams.microsoft.com\/l\/meetup-join\/19%3ameeting_nty0mzm4ndctnje2oc00ymq5ltlmngytyzc2ngu3zjvlmzbj%40thread.v2\/0?context=%7b%22tid%22%3a%22482198bb-ae7b-4b25-8b7a-6d7f32faa083%22%2c%22oid%22%3a%2293ce84d0-7766-4111-980b-f193311ad802%22%7d\u0022\u003EClick here to join the meeting\u003C\/a\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Ca href=\u0022https:\/\/aka.ms\/JoinTeamsMeeting\u0022 target=\u0022_blank\u0022 title=\u0022https:\/\/aka.ms\/jointeamsmeeting\u0022\u003ELearn More\u003C\/a\u003E | \u003Ca href=\u0022https:\/\/teams.microsoft.com\/meetingOptions\/?organizerId=93ce84d0-7766-4111-980b-f193311ad802\u0026amp;tenantId=482198bb-ae7b-4b25-8b7a-6d7f32faa083\u0026amp;threadId=19_meeting_NTY0MzM4NDctNjE2OC00YmQ5LTlmNGYtYzc2NGU3ZjVlMzBj@thread.v2\u0026amp;messageId=0\u0026amp;language=en-US\u0022 target=\u0022_blank\u0022 title=\u0022https:\/\/teams.microsoft.com\/meetingoptions\/?organizerid=93ce84d0-7766-4111-980b-f193311ad802\u0026amp;tenantid=482198bb-ae7b-4b25-8b7a-6d7f32faa083\u0026amp;threadid=19_meeting_nty0mzm4ndctnje2oc00ymq5ltlmngytyzc2ngu3zjvlmzbj@thread.v2\u0026amp;messageid=0\u0026amp;language=en-us\u0022\u003EMeeting options\u003C\/a\u003E\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"EMPOWERING USERS COMMUNICATE THEIR PREFERENCES TO MACHINE LEARNING MODELS IN VISUAL ANALYTICS "}],"uid":"27707","created_gmt":"2020-11-12 15:47:07","changed_gmt":"2020-11-12 15:47:07","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-11-20T16:00:00-05:00","event_time_end":"2020-11-20T18:00:00-05:00","event_time_end_last":"2020-11-20T18:00:00-05:00","gmt_time_start":"2020-11-20 21:00:00","gmt_time_end":"2020-11-20 23:00:00","gmt_time_end_last":"2020-11-20 23:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"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":""}}}
