1Linear kernel, C = 0.01. 2Radian basis function kernel, gamma = 0.009, C = 0.2. 3,4Number of trees = 650, min_samples_split = 2, min_samples_leaf = 1. 5min_samples_split = 5, min_samples_leaf = 30, max_depth = 4. #“Both” means the two PSD feature vectors are appended in column-wise order. Mean accuracy of top-tier classifiers using a 10-fold cross-validation scheme with 20% of the corpus was randomly holdout. Verification results are based on the dataset in Table 1. Note that each species contains both sexes. Mean and standard deviation of accuracy measure over all folds (% mean/SD over). Linear SVC: linear support vector classifier; RBF SVM: radial basis function support vector machine; XGBC: extreme gradient boosting classifier; RF: random forests; X-TREE: extra randomized trees; GBC: gradient boosting classifier. |
