Einladung zum Informatik-Kolloquium des Instituts für Informatik

Am Montag, dem 30.11.2009, wird Prof. Themis Palpanas, University of Trento, Italy, zum Thema Getting the Most Out of Your Streams vortragen.

Abstract:
In the last few years, we have been witnessing an evergrowing need
for continuous observation and monitoring applications. This need
is driven by recent technological advances that have made
streaming applications possible, and by the fact that analysts in
various domains have realized the value that such applications can
provide.

In this presentation, we propose a general framework for computing
efficiently an approximation of multi-dimensional distributions of
streaming data. This framework enables the development of a wide
variety of complex streaming applications. In addition, we
demonstrate how our framework can operate in a distributed fashion,
thus, making better use of the available resources.
We motivate our techniques using two concrete problems, both in the
challenging context of resource-constrained sensor networks. The
first problem is outlier detection, while the second is detection
and tracking of homogeneous regions. Experiments with synthetic and
real data show that our method is efficient and accurate, and
compares favorably to other proposed techniques for both the
problems that we studied.

Veranstaltungsort ist die Oettingenstraße 67, Raum U151.
