SUMMARY:Processing of Aggregations over Big Data Streams
DESCRIPTION:\nOnline analytics and real-time data processing in most
 advanced IoT\, scientific\, business\, and defense applications\, rely
 heavily on the efficient execution of large numbers of Aggregate Continuous
 Queries (ACQs). ACQs continuously aggregate streaming data and periodically
 produce results such as max or average over a given window of the latest
 data.&nbsp\; Low operational cost and timely processing are of paramount
 importance in these applications. To meet these requirements&nbsp\;under
 fixed resources\, we have developed incremental evaluation algorithms as
 well as scheduling\, stream partitioning and load shedding techniques for
 window-based aggregations.&nbsp\; In this talk\, we will first overview our
 aforementioned contributions and then focus on two recent ones\,
 (1)&nbsp\;SlickDeque&nbsp\;that optimizes the execution of multi-ACQs and
 (2)&nbsp\;Concept-driven&nbsp\;load shedding that adapts grouped
 aggregations to changing workloads.\n\n\n\nBio\n\n\n\nPanos K. Chrysanthis
 is a Professor of Computer Science and the founding director of the
 Advanced Data Management Technologies Laboratory in the School of Computing
 and Information at the University of Pittsburgh.&nbsp\; He is also an
 Adjunct Professor at the Carnegie Mellon University and University of
 Cyprus. His research interests lie at the intersection of data
 management&nbsp\;(Big Data\, Databases\, Data Streams &amp\; Sensor
 networks)\, distributed &amp\; mobile computing\, operating and real-time
 systems.&nbsp\; He is a recipient of the NSF CAREER Award&nbsp\;for his
 pioneer work on mobile data management\,&nbsp\;and he is an ACM
 Distinguished Scientist and a Senior Member of IEEE. He is also a recipient
 of the University of Pittsburgh Provost Award for Excellence in Mentoring
 (doctoral students). He is currently the Special Issues Coordinator for the
 Distributed and Parallel Databases Journal and&nbsp\;on the editorial board
 of several journals\, and has repeatedly served as a program committee
 chair and member in all major data management conferences.&nbsp\;He earned
 his BS degree from the University of Athens\, Greece and his MS and PhD
 degrees from the University of Massachusetts at Amherst.\n
