Created ARFF files that will be used for testing in WEKA. I used the following filters: NumericToNominal (for fixing labels), RemoveUseless(99.9) (for removing useless attributes), ReplaceMissingValues (fills in column means for NAs), Randomize (for randomizing the instance order), RemovePercentage (for splitting data in 80% train 20% test). The wholedataset with 50000 instances is in Data.ARFF, training data with 40000 instances in Train.ARFF, and finally test data with 10000 instances in Test.ARFF
