This work addresses the challenge of abrupt temporal metric anomalies in large-scale base station testing, often caused by resource allocation errors, which necessitate efficient unsupervised detection methods. The authors propose CALM, a framework that leverages nonparametric kernel density estimation combined with bootstrap-based dynamic thresholding to enable real-time anomaly detection at the individual testbed level. To mitigate alert fatigue and identify globally significant anomalies, they further introduce AggCALM, which aggregates signals across multiple testbeds. Requiring no labeled data, the approach offers high timeliness and scalability, demonstrating strong performance on both simulated and real-world base station datasets. Beyond ensuring stable operation in complex testing environments, the method is readily transferable to other system health monitoring scenarios.
This study investigates boundedness relationships between the simultaneous 𝒞-number and classical graph parameters, aiming to characterize which parameters can upper-bound the simultaneous 𝒞-number. By leveraging structural graph theory, parameterized complexity, set-representation techniques, closure properties of graph classes, and function-mapping methods, the work establishes for the first time a systematic equivalence between boundedness of parameters such as cliquewidth and mim-width within the simultaneous 𝒞-number framework—while showing that modular-width does not share this property. It also fully characterizes the graph-class conditions under which parameters like treewidth upper-bound the simultaneous 𝒞-number. As an application, the results yield efficient algorithms for the Clique problem on the corresponding graph classes.
