Abstract: In a computer-implemented method for cardinality-based index caching of time series data, a cardinality of an index of a time series data monitoring system is determined. The cardinality of the index is compared to a cardinality threshold. Responsive to determining that the cardinality of the index exceeds the cardinality threshold, the index is cached in a local memory cache of a query node of the times series data monitoring system. Responsive to determining that the cardinality of the index does not exceed the cardinality threshold, the index is cached in a distributed memory cache of the times series data monitoring system.

Abstract: Systems and methods for audio anomaly detection in a voice signal are provided. In some embodiments, a system comprises a voice history database storing historic audio metadata of past voice signals acquired during operation of a user audio device; a data clustering processor, connected to the voice history database and configured for cluster analysis of the historic audio metadata into a normal operation cluster and an anomalous operation cluster and to provide a user audio model therefrom; a voice model database, configured to receive and to store the user audio model; and a classification processor, connected with the voice model database. The classification processor may receive current audio metadata of the voice signal from the user audio device; compare the current audio metadata with the user audio model; and determine if the voice signal corresponds to a normal operating mode or an anomalous operating mode of the user audio device.

Abstract: A method may include configuring a processor to monitor, in an application, composition of an electronic communication addressed to a second user from a first user, the electronic communication associated with a set of parameters; determine an intent of the electronic communication based on the set of parameters; search an associative data structure to retrieve content associated with the intent, the content previously transmitted to a third user from the first user or content(s) received from a fourth user(s); and present a suggestion in the application to include the retrieved content in the electronic communication
