Complex Refractive Indices of Ginseng/American Ginseng Tablets

The data are the computed THz complex refractive indices of Asian ginseng (AsG) and American ginseng (AmG) tablets, used in " Discrimination between Panax ginseng and Panax quinquefolius with Deep Learning Terahertz Spectroscopy". In total there are 42 tablets, split into 6 groups.
Upon decompression of "Dataset.rar", there should be 18 csv files in total. The "data_nj.csv" files (j = 1~6) contains the real refractive index data of the tablet samples from j-th group; "data_aj.csv" files (j = 1~6), are the absorption coefficient data of the tablet samples from j-th group. The first columns in these files are the corresponding frequency, in THz, and the remaining 2nd to 8th column are the optical constants. The units of real refractive indices are R.I.U., while those for absorption coefficients are in cm^-1.
The labels for classification are specified in "label_j.csv" files (j = 1~6), while "1" stands for AsG and "0" for AmG.
