Table 1 Performance of oligo kernel classifiers with oligomer length K = 1,...,6. The first line shows the mean classification error, given in percent, on the test sets. The rates are averages over 50 runs on randomly partitioned data. The second line shows the standard deviation of the classification error. The last line shows the mean over the 50 optimal values of σ which had been chosen from the set {0.5,0.75,1,1.5,2} for each run to minimize the error on a validation set.
