# Referring Expression Comprehension on RefCOCO+ UNC (val) Source: [Referring Expression Comprehension on RefCOCO+ UNC (val)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:58:50.615Z Evaluation of Referring Expression Comprehension performance on the validation split of the RefCOCO+ UNC dataset, 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 (val) | | 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 | 79.74 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-13B | 76.52 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-13B | 74.86 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Llama2-13B | 74.46 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-7B | 74.23 | Not recorded | 68fa729f1e209131cea5799e | | u-LLaVA-7B | 74.09 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Llama2-13B | 73.89 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-7B | 72.81 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-7B | 70.21 | Not recorded | 68fa729f1e209131cea5799e | | u-LLaVA-7B | 68.74 | Not recorded | 68fa729f1e209131cea5799e | | GSVA-Vicuna-13B | 68.14 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Llama2-13B | 67.91 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-13B | 63.77 | Not recorded | 68fa729f1e209131cea5799e | | LISA-Vicuna-7B | 62.92 | Not recorded | 68fa729f1e209131cea5799e | ### GSVA-Llama2-13B Precision@0.5 IoU: 79.74.
