Evaluation of Long-tailed Recognition performance on the test split of the ImageNet-LT Backward-LT dataset, reporting Top-1 Accuracy segmented by Inverse Ranking (IR) groups (IR=2 to IR=50).

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 | Long-tailed Recognition |
| Dataset (including any stated split) | ImageNet-LT Backward-LT (test) |
| Metric | Top-1 Acc (IR=2) |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 7 of 7 |
| 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.
