Table 3.
Precision, recall, and F-score of species identification by Xception in color class experiment. F/M within a parenthesis represents female/male. Precision is the number of correct predictions as a certain class divided by the number of all predictions as the class returned by Xception. Recall, which is equivalent to sensitivity, is the number of correct predictions as a certain class divided by the number of test datasets as the class. F-score is the harmonic average of the precision and recall, (2 × precision × recall)/(precision + recall).
