Classification: CPC G  B | IPC B  G

Claim 11:
12. A chemical sensing system, comprising:
a plurality of sensors arranged on at least one substrate, wherein a first sensor and a second sensor of the plurality of sensors have different sensitivities to sense at least one analyte in a sample, each of the plurality of sensors being configured to output a signal in response to sensing the at least one analyte; and
a computer processor programmed to:
receive the signals output from the plurality of sensors; and
determine a concentration of the at least one analyte in the sample based, at least in part, on the received signals and a model trained to relate the signals or information derived from the signals to an output representation having bases corresponding to analytes, the analytes including the at least one analyte, wherein the concentration is a scalar value in conjunction with a particular unit of measurement,
wherein the model comprises:
a first model relating the signals output from the plurality of sensors to a feature representation; and
a second model relating the feature representation to the output representation, the second model comprising:
a first sub-model relating a straightened orthogonal representation to the output representation, wherein the sub-model:
relates the straightened orthogonal representation to a non-linearized output representation having standard bases associated with the analytes; and
relates the non-linearized output representation to the output representation; and
wherein a change in a location of a point in the output representation corresponding to an analyte concentration in the sample is a linear function of a change in the analyte concentration in the sample.
