Mining Large Time-evolving Data Using Matrix and Tensor Tools
SDM 2007 tutorial, Minneapolis, MN
DESCRIPTION - OBJECTIVES
How can we find patterns in sensor streams (eg., a
sequence of temperatures, water-pollutant measurements, or
machine room measurements)?
How can we mine Internet traffic graph over time?
Further, how can we make the process incremental?
We review the state of the art in four related fields:
(a) numerical analysis and linear algebra (b) multi-linear/tensor analysis
(c) graph mining and (d) stream mining.
We will present both theoretical results and algorithms as well as
case studies on several real applications.
Our emphasis is on the intuition behind each method,
and on guidelines for the practitioner.
