Evaluation of Unsupervised Domain Adaptation for Person Re-identification, specifically testing transfer from the MSMT17 dataset to the Market-1501 test set, typically measured using mAP and Rank-1 accuracy.

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 | Unsupervised Domain Adaptation Person Re-identification |
| Dataset (including any stated split) | MA2MS MSMT17 to Market-1501 (test) |
| Metric | mAP |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 9 of 9 |
| 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

- [mAP](<https://www.sota2.com/research/sota/unsupervised-domain-adaptation-person-re-identification-on-ma2ms-msmt17-to-market-1501-test.md?metric=mAP>): Higher is better; unit: PERCENT.

- [Rank-1 Accuracy](<https://www.sota2.com/research/sota/unsupervised-domain-adaptation-person-re-identification-on-ma2ms-msmt17-to-market-1501-test.md?metric=Rank-1%20Accuracy>): Higher is better; unit: PERCENT.
