| # refcoco-grounding |
|
|
| Human referring expressions from RefCOCO, RefCOCO+ and RefCOCOg, joined to COCO2014. |
|
|
| One shared image cache and mirror; views retain their native question identities. |
| The union of all held-out image IDs is reserved from training across variants; |
| overlapping validation/test images stay in test only. Original split names and |
| per-image Flickr licenses are recorded without excluding noncommercial or |
| unresolved sources. Original images are redistributed unchanged; optional pixel |
| augmentations remain subject to each image's original terms. |
| Only native COCO object boxes supply options; no invented distractors. |
|

| Original data: [jxu124/refcoco](https://huggingface.co/datasets/jxu124/refcoco), [jxu124/refcocoplus](https://huggingface.co/datasets/jxu124/refcocoplus), [jxu124/refcocog](https://huggingface.co/datasets/jxu124/refcocog), [Untitled111/refcoco-train2014-assets](https://huggingface.co/datasets/Untitled111/refcoco-train2014-assets). Repackaged as parquet for [tasksource](https://github.com/sileod/tasksource) by [scripts/repackage_dataset/grounding.py](https://github.com/sileod/tasksource/blob/main/scripts/repackage_dataset/grounding.py#L88). |

| Images are stored once with grouped `qa` records: train: 100,000 questions / 8,526 image groups, validation: 24,527 questions / 2,566 image groups, test: 30,903 questions / 3,980 image groups. |
