This has resulted in temporally\nand spatially data-rich environment that provides unprecedented opportunities\nfor improving complex system operations in various applications including\nmanufacturing, healthcare, emerging energy systems, etc. Meanwhile, it also raises\nnew research challenges on data analysis and decision making\ndue to the complex data structures of waveform signals, such as heterogeneous\ndata dependency, high-dimensional and non-stationary characteristics. In this\ntalk, two topics will be discussed in detail to present the essential need of\nmultidisciplinary efforts in the development of new engineering-driven data\nanalysis methods for effectively analyzing waveform signals. In the first topic,\na new method of \u201chierarchical non-negative Garrote for group variable selection\u201d\nwill be presented, which is developed for informative sensor and feature selection\namong massive multistream sensing signals. The second topic is to discuss a new\nmethod for \u201ccharacterization of nonlinear profiles variations using mixed-effect\nmodels and wavelets\u201d, which is developed to effectively model both within-profile\nvariations and between-profile variations for enhancing variation root cause diagnosis.\nAfterwards, a brief overview of my other research topics will also be presented.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Waveform Signal Analysis for System Performance Improvement"}],"uid":"27187","created_gmt":"2011-11-16 12:14:21","changed_gmt":"2016-10-08 01:56:37","author":"Anita Race","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2011-11-22T10:00:00-05:00","event_time_end":"2011-11-22T11:00:00-05:00","event_time_end_last":"2011-11-22T11:00:00-05:00","gmt_time_start":"2011-11-22 15:00:00","gmt_time_end":"2011-11-22 16:00:00","gmt_time_end_last":"2011-11-22 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EJennifer Harris\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
