Abstract We describe the Artificial Neural Networks （ANNS） and its appli-cation in Raman Spectrum data processing. Studing the back-propagation neu- ral network with different learning rate coefficients （μ）， we found that the net-works performed optimally when the value of μ was 0．5． By comparing the re- sults of the process and the original data， we illustrated that the networks with the sigmoid transfer functions could correct the slight spectral distortions， ob-tain better signal－to－noise ratios， and it could improve the resolution a little.
