GraphTS: Graph-represented time series for subsequence anomaly detection

R Zarei, G Huang, J Wu - Plos one, 2023 - journals.plos.org
Automatic detection of subsequence anomalies (ie, an abnormal waveform denoted by a
sequence of data points) in time series is critical in a wide variety of domains. However, most …

On the Complexity of 2-club Cluster Editing with Vertex Splitting

FN Abu-Khzam, T Davot, L Isenmann… - arXiv preprint arXiv …, 2024 - arxiv.org
Editing a graph to obtain a disjoint union of s-clubs is one of the models for correlation
clustering, which seeks a partition of the vertex set of a graph so that elements of each …
