Among them, the gas concentration prediction performance of E-nose mainly depends on the goodness of the prediction model. Deep learning algorithms can utilize their multilayer networks to extract features from raw data, however, the current application of deep learning algorithms for gas concentration prediction of E-nose is still insufficient, and the prediction results using traditional neural networks often fail to be very fine.
