ABSTRACT:
A method for identifying a chemical substance from a set of output states provided by a chemical sensor array being exposed to the chemical substance, the method including: selecting, with an evaluation circuit, from a set of class descriptions for different chemical substances a first class description and one or more further class descriptions, wherein the first class description is related to a first chemical substance and a further class description is related to a further chemical substance; and estimating, with one or more estimating units, a first likelihood value and one or more further likelihood values, wherein the first likelihood value represents a probability that the set of output states corresponds to the first class description, and a respective further likelihood value represents a probability that the set of output states corresponds to a respective further class description.
