  1. This table shows the LOOCV error rates when no seed is inserted in group 1 and five seeds of length 6 are inserted in group 2 with the seed density 0.005.
  2. “# of selected” indicates the number of feature selected in each level. “features” indicates the k-tuple feature with the particular value of k. “all” is the situation when all the 4k features are used. “-” is the feature selection level does not exist for the particular k value. “NaN” means the method failed to converge to a result within a given amount of time.
