Table 1.
Performance of the individual human experts and the neural network on the test set. Note that high percentages of correct identifications are associated with high percentages of incorrect identifications, and vice versa.
identifier | % correct | % ambiguous | % incorrect |
---|---|---|---|
Expert 1 | 67 | 3 | 31 |
Expert 2 | 58 | 25 | 17 |
Expert 3 | 58 | 25 | 17 |
Expert 4 | 42 | 44 | 14 |
Expert 5 | 58 | 22 | 19 |
neural network (no ambiguous cases) | 86 | 0 | 14 |
neural network (0.4–0.6 treated as ambiguous) | 67 | 22 | 11 |
