a, Confusion matrix of the actual class and predicted class for recognizing 8 gases (A: acetone, C: carbon monoxide, E: ethanol, F: formaldehyde, N: nitrogen dioxide, T: toluene, H: hydrogen, I: isobutylene) by using the testing data collected in the 2nd month. b, Confusion matrix of the actual class and predicted class for recognizing 8 gases by using the testing data collected in the 3rd month. c, Prediction accuracy by using the 1st month data as the training data and the 2nd and 3rd months data as the testing data.
