A Mutually Exciting Latent Space Hawkes Process Model for Continuous-time Networks
Zhipeng Huang, Hadeel Soliman, Subhadeep Paul +1
Networks and temporal point processes serve as fundamental building blocks for modeling complex dynamic relational data in various domains. We propose the latent space Hawkes (LSH)…
Multi-criteria Anomaly Detection using Pareto Depth Analysis
Ko-Jen Hsiao, Kevin S. Xu, Jeff Calder +1
We consider the problem of identifying patterns in a data set that exhibit anomalous behavior, often referred to as anomaly detection. In most anomaly detection algorithms, the dis…
Adaptive Evolutionary Clustering
Kevin S. Xu, Mark Kliger, Alfred O. Hero
In many practical applications of clustering, the objects to be clustered evolve over time, and a clustering result is desired at each time step. In such applications, evolutionary…
