The calculation of basis spectra from a spectral library is an important prerequisite of any compact imaging spectrometer. In this paper. we compare the basis spectra computed by singular-value decomposition (SVD) and principal component analysis (PCA) in terms of estimation performance with respect to resolution. presence of noise. https://csdtbeldfov3p.timeblog.net/70682667/adaptive-spp-cnn-lstm-att-wind-farm-cluster-short-term-power-prediction-model-based-on-transitional-weather-classification
