Linear-time Detection of Non-linear Changes in Massively High Dimensional Time Series

no code implementations28 Oct 2015 Hoang-Vu Nguyen, Jilles Vreeken

Change detection in multivariate time series has applications in many domains, including health care and network monitoring.

Change Detection Time Series +1

Flexibly Mining Better Subgroups

no code implementations28 Oct 2015 Hoang-Vu Nguyen, Jilles Vreeken

For nominal attributes, this is relatively straightforward, as we can consider individual attribute values as binary features.

Attribute Subgroup Discovery

Canonical Divergence Analysis

no code implementations28 Oct 2015 Hoang-Vu Nguyen, Jilles Vreeken

We aim to analyze the relation between two random vectors that may potentially have both different number of attributes as well as realizations, and which may even not have a joint distribution.

Universal Dependency Analysis

no code implementations28 Oct 2015 Hoang-Vu Nguyen, Jilles Vreeken

For practical use, such a measure should be universal in the sense that it captures correlation in subspaces of any dimensionality and allows to meaningfully compare correlation scores across different subspaces, regardless how many dimensions they have and what specific statistical properties their dimensions possess.
