摘要
Low-cost tin oxide gas sensors are inherently nonspecific, In addition, they have several undesirable characteristics such as slow response, nonlinearities, and long-term drifts, This paper shows that the combination of a gas-sensor array together with self-organizing maps (SOM's) permit success in gas classification problems, The system is able to determine the gas present in an atmosphere with error rates lower than 3%. Correction of the sensor's drift with an adaptive SOM has also been investigated.
