A two-layer nested cross-validation (CV) is applied to select and evaluate models, where outer CV randomly splits the dataset into 10 folds with 9 as validation set, and inner CV then randomly splits validation set to 10 folds with 9 as training set. The whole procedure is performed 30 times, and the average performance is computed over these trails. Possible parameters of a graph kernel are also tuned during this procedure. |
