# Referring Expression Comprehension on RefCOCO UNC (test-A) Source: [Referring Expression Comprehension on RefCOCO UNC (test-A)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:58:50.580Z Evaluation of Referring Expression Comprehension performance on the test-A split of the RefCOCO UNC dataset. 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 | Referring Expression Comprehension | | Dataset (including any stated split) | RefCOCO UNC (test-A) | | Metric | Precision@0.5 IoU | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 14 of 14 | | 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 - [Precision@0.5 IoU](): Higher is better; unit: PERCENT. ## Recorded results | Method | Precision@0.5 IoU | Result date | Report paper | | --- | --- | --- | --- | | GSVA-Llama2-13B | 92.08 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-13B | 90.49 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Llama2-13B | 89.54 | Not recorded | 68fa729f1e209131cea5799e | | u-LLaVA-7B | 89.47 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-7B | 89.22 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-13B | 89.05 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-7B | 88.84 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Llama2-13B | 88.84 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-7B | 88.01 | Not recorded | 68fa729f1e209131cea5799e | | u-LLaVA-7B | 87.13 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-13B | 87.01 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Llama2-13B | 85.56 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-13B | 83.26 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-7B | 81.72 | Not recorded | 68fa729f1e209131cea5799e | ### GSVA-Llama2-13B Precision@0.5 IoU: 92.08.
