Abstract: A data processing apparatus is provided that includes storage circuitry that stores a plurality of future time series forecasters of an aspect of a system and, for each of the future time series forecasters, a representation of a confidence interval associated with that future time series forecaster. Unknown-unknown detection circuitry determines whether a new measurement falls outside confidence intervals generated from the representation of the confidence interval associated with each future time series forecaster of the aspect of the system, and in response to the new measurement falling outside the confidence intervals, labels the new measurement as an unknown-unknown.
