1. A method for monitoring of industrial devices, the method comprising:
receiving sensor signal data of one or more industrial devices and one or more events associated with operation of the one or more industrial devices;
identifying, using a first autoencoder, an abnormal behavior of the one or more industrial devices based on the sensor signal data;
creating or updating an additional autoencoder based on the sensor signal data associated with a time window relating to the abnormal behavior;
associating one or more of the events located within the time window with the additional autoencoder, wherein the one or more events are associated with textual information, and wherein the textual information is used to assign a cause for the abnormal behavior to the additional autoencoder for transmission of a notification; and
transmitting, by the additional autoencoder, the notification after the identifying of the abnormal behavior, wherein the notification comprises the textual information associated with the additional autoencoder.
