Data for: A near-infrared hyperspectral data recognition algorithm for construction waste and its experimental study

Including "training_data" and "testing_data", both of them have 225 cols, which has 224 reflectivity in bands range 900 to 1700nm and the last cols represent the tabel of corresponding row. In the data sets, label"1" is represent wood, label "2" is represent "plastic", label "3" is represent "brick", label "4" is represent "concrete", label 5 is represent "black brick", and label "7" is represent rubber. There is no label "6" because the rubber is special because it's color, I want rubber as the final label. So the "6" is reserved.
