1. An encoder device for determining a kinematic value of the movement of a first object relative to a second object, wherein the encoder device comprises:
a standard associated with the first object;
at least one scanning unit associated with the second object for producing at least one scanning signal by detection of the standard; and
a control and evaluation unit that is configured to determine the kinematic value from the at least one scanning signal,
wherein the control and evaluation unit is further configured to determine the kinematic value by an evaluation of the at least one scanning signal using a method of machine learning, with the method of machine learning being pre-trained with a plurality of scanning signals and associated kinematic values.
