# Referring Expression Comprehension on RefCOCO+ UNC (test-A) Source: [Referring Expression Comprehension on RefCOCO+ UNC (test-A)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:58:11.306Z Evaluation of Referring Expression Comprehension performance on the test-A split of the RefCOCO+ UNC dataset, typically measured using Prec@0.5 IoU. 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 | Prec@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 - [Prec@0.5 IoU](): Higher is better; unit: PERCENT. ## Recorded results | Method | Prec@0.5 IoU | Result date | Report paper | | --- | --- | --- | --- | | GSVA-Llama2-13B | 84.45 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-13B | 81.69 | Not recorded | 68fa729f1e209131cea5799e | | u-LLaVA-7B | 81.16 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-13B | 81.08 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Llama2-13B | 80.56 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-7B | 79.46 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Llama2-13B | 79.1 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-7B | 78.78 | Not recorded | 68fa729f1e209131cea5799e | | u-LLaVA-7B | 76.32 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-7B | 75.62 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-13B | 73.9 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Llama2-13B | 73.77 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-13B | 70.24 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-7B | 68.93 | Not recorded | 68fa729f1e209131cea5799e | ### GSVA-Llama2-13B Prec@0.5 IoU: 84.45.
