This is the cod-rna dataset, retrieved 2014-11-14 from the libSVM site. Additional to the preprocessing done there (see LibSVM site for details), this dataset was created as follows:
-join test, train and rest datasets
-normalize each file columnwise according to the following rules:
-If a column only contains one value (constant feature), it will set to zero and thus removed by sparsity.
-If a column contains two values (binary feature), the value occuring more often will be set to zero, the other to one.
-If a column contains more than two values (multinary/real feature), the column is divided by its std deviation.
NOTE: 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!
