Table 5. Validation of species counts against expert classifications for image sets with a single species.
| Species Counts | * Validated | Proportion Exactly Correct | Proportion within+/−1 bin |
|---|---|---|---|
| 1 | 1,662 | 0.975 | 1.000 |
| 2 | 626 | 0.827 | 1.000 |
| 3 | 401 | 0.721 | 0.965 |
| 4 | 309 | 0.621 | 0.942 |
| 5 | 213 | 0.507 | 0.897 |
| 6 | 202 | 0.386 | 0.797 |
| 7 | 136 | 0.397 | 0.794 |
| 8 | 98 | 0.286 | 0.653 |
| 9 | 84 | 0.298 | 0.726 |
| 10 | 54 | 0.185 | 0.704 |
| 11–50 | 456 | 0.713 | 0.776 |
| 51+ | 16 | 0.438 | 0.938 |
* Validated is the total number of counts validated by experts. Proportion Exactly Correct reflects the proportion of algorithm-derived counts that matched expert classifications exactly. Proportion within +/−1 reflects the proportion of algorithm-derived accounts that fell within 1 count bin above or below the expert classification.
