Abstract: In certain embodiments, a method includes recursively performing a procedure that includes using an allowed set of object identifiers and a hash function to update a bit array, using a disallowed set of object identifiers and the hash function to further update the bit array where collisions occur, repeating the process with a new allowed set that includes object identifiers from the original allowed set that collided with the disallowed set and a new hash function, until reaching a round where no collisions occurred, generating a data structure that includes the bit arrays created during each recursive round, and compressing the data structure.

Abstract: Systems and methods are provided for automated anomaly detection model quality assurance (QA) and deployment for wireless network failure prediction. Network failure prediction can leverage models trained to detect issues on a network and predict failure scenarios by identifying anomalous issues indicative of failure conditions. To keep these models up to date with changes in network behavior and configurations, the models are recalibrated from time to time. Implementations disclosed herein provide for automated evaluation and deployment of recalibrated models, while assuring issue detection results from the recalibrated models accurately reflect current network conditions. To do this, implementations disclosed herein determine QA metrics for recalibrated, candidate models, QA thresholds from previously deployed models, and QA criteria from a currently deployed model.
