Abstract
An anomaly detector for controlling a system is provided. The system comprises one or multiple tools to perform one or multiple tasks. The anomaly detector collects a feedforward signal indicative of a sequence of control inputs to the plurality of actuators and a feedback signal indicative of a sequence of outputs of the system caused by the plurality of actuators operated based on the sequence of control inputs. The anomaly detector further combines input state variables extracted from the feedforward signal and output state variables extracted from the feedback signal to form a sequence of extended states of the system. The attention model further encodes the sequence of extended states to produce an encoding of each extended state of the sequence of extended states in a latent space. The anomaly detector further detects an anomaly in a current operation of the system based on the encoded sequence of extended states.
