XCB poly-radio devices as finders, locators, scanners, sensors, and Bluetooth (BT) radio topology reporters as part of a global lost-and-found services system. XCB devices function as “smart objects” and combine dual transceivers operating in the telecommunications and the low power ISM radio spectra, with default power management overrides under local control of the BT modem. “Familiar zones” are defined, and a “familiarity index” versus a “strangeness index” based on meta-analysis of BT radio contact logs are used to assign location. Location, in concert with other sensor data, is coupled to conditional logic rules programmable by the user or the system administrator. Locations, determined by monitoring familiar and unfamiliar BT radio topology, trigger executable commands to smartphones, to smart devices generally, and to remote machines, and can for example, generate alerts to a user if radiotagged assets, children or pets have strayed, are lost, or are left behind. When tied to cloud predictive services or increased edge computing capacity, incipient loss of radiotag objects can be detected before an owner knows the smart object is lost. In another embodiment, XCB devices having a novel chip architecture for improved power management of cellular and MCU circuits mediated by BT radio modem that achieves “situational awareness” by monitoring the BT signal environment around the device.

A system manager is implemented on one or more computing devices operating according to special-purpose instructions to detect anomalies and iteratively collect feedback for model re-evaluation. The system manager trains a machine learning model to detect anomalies and determines an accuracy score of the trained model at detecting anomalies in a set of data items. The system manager also determines a contiguous anomaly score value region that includes a threshold portion of incorrectly labeled outputs. The trained model is used to make predictions on production data, and the system manager determines an accuracy of the predictions by selecting a subset of the production data within the contiguous anomaly score value region, clustering the subset into clusters, and selectively sampling data items from the clusters. The accuracy of the predictions on the production data is combined with the accuracy score of the trained model to determine an updated accuracy score. The system manager determines whether to retrain the model based on the updated accuracy score.
