The preprocessing python script works for the following tested datasets at least:

• USPS: [https://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/multiclass.html#usps]
• Skin_nonskin: [https://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/binary.html#skin_nonskin]
• gas sensor: [https://archive.ics.uci.edu/ml/datasets/Gas+Sensor+Array+Drift+Dataset+at+Different+Concentrations]
  • (semi-auto) please manually remove semicolon in the raw data

Usage of preprocessing script:

Usage: python dataPreprocessing.py <flag> <path/of/inputDataset> <path/of/outputDataset> <name>, flag 0 for LIBSVM; 1 for UCI repository 
for example: python dataPreprocessing.py 0 datasets/ datasets/ skin_nonskin
