Abstract: For improved provision of an alarm relating to an accuracy of a trained function, such as detecting an accuracy decrease of a trained function under a distribution drift of incoming data, the following computer-implemented method is suggested: receiving input data messages (140) relating to at least one variable of at least one device (142); applying a trained function (120) to the input data messages (140) to generate output data (152), the output data (152) being suitable for analyzing, monitoring, operating and/or controlling the respective device (142); determining at least one respective distance of the respective variable of a respective received input data message (140) to a reference data set, determining an accuracy value of the trained function (120) using the respective distance and a regression model (130); and if the determined accuracy value is smaller than an accuracy threshold: providing an alarm (150) relating to the determined accuracy value to a user, to the respective device (142) and/or a

Abstract: For improved provision of an alarm relating to anomaly scores assigned to input data, a method includes receiving input data relating to at least one device. The input data includes incoming data batches X relating to at least N separable classes. Respective anomaly scores are determined for the respective incoming data batch X relating to the at least N separable classes using N anomaly detection models. The anomaly detection models are applied to the input data to generate output data. A difference is determined, for the respective incoming data batch X, between the determined respective anomaly scores for the at least N separable classes and given respective anomaly scores of the N anomaly detection models. When the respective determined difference is greater than a difference threshold, an alarm relating to the determined difference is provided to a user, the respective device, and/or an IT system connected to the respective device.
