SUMMARY:Brown bag: Immanuel Trummer
DESCRIPTION:Title: Query optimization for data analysis\nSpeaker:
	 Immanuel Trummer\nAbstract: Business and industry and almost all
	 scientific disciplines rely nowadays on large-scale data analysis. Some
	 of the most popular analysis tools offer declarative interfaces where
	 users simply describe the data they need instead of specifying how to
	 generate it. In order to enable such interfaces\, we must however solve
	 the NP-hard query optimization problem. \n\nIn this talk\, I will give
	 an overview of my recent work on query optimization. I will explain how
	 the specific context of large-scale data analysis motivates novel
	 problem variants that are particularly hard to solve. Then I will show
	 how techniques such as approximation\, parallelization\, and
	 pre-processing make solving those problems under real-time constraints
	 practical. I will quickly cover recent results of a collaboration with
	 NASA in which we used a D-Wave 2X adiabatic quantum computer for solving
	 certain query optimization variants. Finally\, I will discuss a project
	 on large-scale text mining and machine learning at Google Mountain View
	 that could benefit from all proposed techniques. \n\nAt the end of the
	 talk\, I will give an overview of future and ongoing projects in the
	 database group. \n\nBiography: Immanuel Trummer is assistant professor
	 for computer science at Cornell University. His research led to various
	 publications at the main database conferences\, his publications were
	 selected for the ACM SIGMOD Research Highlight Award\, for \"Best of
	 VLDB\"\, and for publication in CACM as CACM Research Highlight. He is
	 recipient of the European Google PhD Fellowship in structured data
	 analysis and alumnus of the German National Academic Foundation
	 (\"Studienstiftung des deutschen Volkes\").
