run for X = 50,100,150,200,250,300,350,400,all (so all graphs get 9 x values) and send me the results in exactly the same format and try the following variants: 1) {log,noLog} the attributes 2) it is known tht descritization can improve naiveBayes. so, for NB, try {none,3bins,5bins,10bins} , equal width bins (and for none, use the current gaussian) note that combinations of (1) * (2) will include logging and not logging , then descritizing, not descritizing. for all the above, generate graphs like the pdfs in results/*.pdf
