Additional to the preprocessing done there (see LibSVM site for details), this dataset was created as follows: \n-join test, train and rest datasets   \n-normalize each file columnwise according to the following rules:    \n-If a column only contains one value (constant feature), it will set to zero and thus removed by sparsity.    \n-If a column contains two values (binary feature), the value occuring more often will be set to zero, the other to one.    \n-If a column contains more than two values (multinary\/real feature), the column is divided by its std deviation.    \n\nNOTE: please keep in mind that cod-rna has many duplicated data points, within each file (train,test,rest) and also accross these files. these duplicated points have not been removed!",
