Further, convolution kernels of three different sizes are adopted in the third convolutional layer, which learns features of different sizes hidden in the spectral data from the raw spectral data. In this disclosure, data is not pre-processed, and the original data may be directly processed. This method has a high generalization ability when a spectral noise distribution of a test set is different from that of a training set.
