Consistency of a range of penalised cost approaches for detecting multiple changepoints
Chao Zheng, Idris A. Eckley, Paul Fearnhead
A common approach to detect multiple changepoints is to minimise a measure of data fit plus a penalty that is linear in the number of changepoints. This paper shows that the genera…
Subset Multivariate Collective And Point Anomaly Detection
Alexander T M Fisch, Idris A Eckley, Paul Fearnhead
In recent years, there has been a growing interest in identifying anomalous structure within multivariate data streams. We consider the problem of detecting collective anomalies, c…
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…
