Subspace Clustering of Very Sparse High-Dimensional Data
Hankui Peng, Nicos Pavlidis, Idris Eckley +1
In this paper we consider the problem of clustering collections of very short texts using subspace clustering. This problem arises in many applications such as product categorisati…
A linear time method for the detection of point and collective anomalies
Alexander T. M. Fisch, Idris A. Eckley, Paul Fearnhead
The challenge of efficiently identifying anomalies in data sequences is an important statistical problem that now arises in many applications. Whilst there has been substantial wor…
Minimum Spectral Connectivity Projection Pursuit
David P. Hofmeyr, Nicos G. Pavlidis, Idris A. Eckley
We study the problem of determining the optimal low dimensional projection for maximising the separability of a binary partition of an unlabelled dataset, as measured by spectral g…
