BP Neural Network Applying in NIR Spectrum Data Processing

In NIR (Near Infrared) spectrum analysis NIR spectrum data is complicated, so it is difficult to analysis the NIR spectrum data. Adopting the linear processing method the data deviation will influence the measuring result. But BP neural network applying in NIR spectrum detection can effectively avoid the data deviation influence. So the paper brings the method of applying BP neural networks in NIR spectrum measurement system, and designs the structure of BP neural network, and establishes correction model by BP neural network.
