Distortion classification and Hotspot recognition dataset

The first column of the sample is wavelength, the second column is reflectance, and the third column is category. In the hotspot recognition dataset, category "0" represents no hotspot occurrence, while category "1" represents hotspot occurrence. In the distortion recognition dataset, category "1" represents "normal spectrum", category "2" represents "broadened distortion spectrum", category "3" represents "asymmetric distortion spectrum", and category "4" represents "broadened and asymmetric distortion spectrum"
