Spectral Characteristic Analysis and Spectral Identification of Desert Plants in Yanchi, Ningxia
Fig. 1. The original reflectance spectra of desert grassland plants
Fig. 2. Obfuscation matrix of random forest model Note: the off-diagonal bubbles represent misjudgment, and the size of the bubbles represents the number of judgment. The larger the number of samples, the larger the bubble
Fig. 3. Variale importance of random forest classification model Note: The blue column in the figure is the importance of the variable. The larger the value of the variable, the stronger the importance of the variable. The yellow column is the Gini coefficient. The higher the coefficient, the better the classification cut
