Evaluation of Medical Re-identification performance on the CXR CheXpert dataset, typically measured using Rank-1 (R1) and mean Average Precision (mAP).

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Medical Re-identification |
| Dataset (including any stated split) | CXR CheXpert (external) |
| Metric | R1 |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 3 of 3 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [R1](<https://www.sota2.com/research/sota/medical-re-identification-on-cxr-chexpert-external.md?metric=R1>): Higher is better; unit: PERCENT.

- [mAP](<https://www.sota2.com/research/sota/medical-re-identification-on-cxr-chexpert-external.md?metric=mAP>): Higher is better; unit: PERCENT.
