This dissertation contributes unified graph-based algorithms and models to help solve large-scale societal problems affecting millions of individuals\u0027 daily lives, from cyber-attacks involving malware to tobacco and alcohol addiction. The main thrusts of our research are:\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E(1) Propagation-based Graph Mining Algorithms: We develop graph mining algorithms to propagate information between the nodes to infer important details about the unknown nodes. We present three examples: AESOP (patented) unearths malware lurking in people\u0027s computers with a 99.61% true positive rate at 0.01% false positive rate; our application of ADAGE on malware detection (patent-pending) enables to detect malware in a streaming setting, and EDOCS (patent-pending) flags comment spammers among 197 thousand users on a social media platform accurately and preemptively.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E(2) Graph-induced Behavior Characterization: We derive new insights and knowledge that characterize certain behavior from graphs using statistical and algorithmic techniques. We present two examples: a study on identifying attributes of smoking and drinking abstinence and relapse from an addiction cessation social media community; and an exploratory analysis of how company insiders trade.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EOur work has already made impact to society: deployed by Symantec, AESOP is protecting over 120 million people worldwide from malware; EDOCS has been deployed by Yahoo and is guarding multiple online communities from comment spammers.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Graph-based Algorithms and Models for Security, Healthcare, and Finance"}],"uid":"27690","created_gmt":"2016-02-26 12:43:05","changed_gmt":"2016-10-08 02:16:45","author":"Jacquelyn Strickland","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-03-11T10:00:00-05:00","event_time_end":"2016-03-11T12:00:00-05:00","event_time_end_last":"2016-03-11T12:00:00-05:00","gmt_time_start":"2016-03-11 15:00:00","gmt_time_end":"2016-03-11 17:00:00","gmt_time_end_last":"2016-03-11 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"119191","name":"PhD Dissertation Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
