1. A sensor device comprising:
a vision sensor that comprises a pixel array having a plurality of pixels each being configured to receive light and to perform photoelectric conversion to generate an electrical signal, based on which electrical signals a data stream is formed;
encoding circuitry that receives the data stream and generates a series of representations that represent states of the data stream;
trigger circuitry that is configured to receive a current representation from the encoding circuitry, to compare the current representation with a reference representation, and to generate trigger signal based on said comparison; and
processing circuitry configured to
receive the trigger signals and to carry out predetermined processing based on representations for which the predetermined processing was indicated to be allowed by the respective trigger signal, and
use a first machine learning module to carry out the predetermined processing.
