# Referring-expression grounding on RefCOCOg Avg Source: [Referring-expression grounding on RefCOCOg Avg]() Collection index: [llms.txt]() Data updated: 2026-06-09T10:44:20.729Z Evaluation of Referring Expression Grounding performance on the RefCOCOg Avg split/average, reporting Accuracy at IoU threshold 0.5. 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 grounding | | Dataset (including any stated split) | RefCOCOg Avg | | Metric | Accuracy@0.5 | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 4 of 4 | | 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 - [Accuracy@0.5](): Higher is better; unit: PERCENT. ## Recorded results | Method | Accuracy@0.5 | Result date | Report paper | | --- | --- | --- | --- | | Visual Para-Thinker++ (3B) | 89.8 | Not recorded | 6a279e5b90966ade919bfa4c | | Visual Para-Thinker (3B) | 87.1 | Not recorded | 6a279e5b90966ade919bfa4c | | Sequential | 85 | Not recorded | 6a279e5b90966ade919bfa4c | | Qwen2.5-VL-3B | 83.9 | Not recorded | 6a279e5b90966ade919bfa4c | ### Visual Para-Thinker++ (3B) Accuracy@0.5: 89.8.
