Change-point detection in variance-covariance matrix
Ying Lin, Benjamin Poignard
We consider the joint estimation of change-point locations and the sparsity pattern of the variance-covariance matrix, which is assumed to evolve in a piecewise constant manner. By…
Beyond Static Bias: Adaptive Multi-Fidelity Bandits with Improving Proxies
Muyun Lu, Haoyang Hong, Huazheng Wang +1
As an extension of the classical multi-armed bandit problem, multi-fidelity multi-armed bandits (MF-MAB) enable individual arms to be evaluated using diverse feedback sources that…
FCOM: A Federated Collaborative Online Monitoring Framework via Representation Learning
Tanapol Kosolwattana, Huazheng Wang, Raed Al Kontar +1
Online learning has demonstrated notable potential to dynamically allocate limited resources to monitor a large population of processes, effectively balancing the exploitation of p…
Online Modeling and Monitoring of Dependent Processes under Resource Constraints
Tanapol Kosolwattana, Huazheng Wang, Ying Lin
Adaptive monitoring of a large population of dynamic processes is critical for the timely detection of abnormal events under limited resources in many healthcare and engineering sy…
