# Changelog

All notable changes to **`nvidia/PhysicalAI-VANTAGE-Bench`** on Hugging Face.

## 2026-05-18

- Dataset card refresh based on Slack review feedback:
  - **Tasks and Submission Formats** table: Single Object Tracking now categorized as `Spatio-Temporal`. Metric updates: `2D Object Localization → F1@0.5`, `2D Referring Expressions → mIoU`, `Single Object Tracking → AUC`. The per-task submission-format column has been removed; expected formats and the leaderboard will be published soon.
  - **Metric Notes** refreshed: added `mIoU`, `F1@0.5`, `AUC`; dropped `mAP@IoU`, `Acc@IoU`, `HOTA`.
  - **Dataset Quantification** table: `Videos` column renamed to `Media`. Per-task counts updated. Totals now report `Total Entries (Annotations): 35,027` and `Total Media Samples (across tasks, with overlaps): 3,346`.
  - **Evaluation Server** description: clarified that the GitHub repo is a sample evaluation pipeline. Predictions are submitted to the official leaderboard, live by end of May 2026.
  - **Task overview figure** in References now renders full-width via inline HTML `<img width="100%">`.

## 2026-05-15

- Per-task `prompt.json` added under `data/2dbbox/` and
  `data/dense_captioning/` (schema: `{"prompt": "<text>"}`).
- Question-only annotation JSONs added under
  `data/vqa/data_jsons/annotations/`,
  `data/temporal_localization/data_jsons/annotations/`,
  `data/event_verification/filtered/**`,
  and `data/referring/refdrone_test_llava.json`. Answer fields
  (`gt`, `gt_option`, `answer`, GT bbox coordinates, etc.) are
  stripped — only the question side ships.
- `Metropolis2DPointing` references renamed to `Vantage2DPointing`.
- New `data/README.md` summarizing the dataset layout and listing the
  per-task prompts.

## 2026-05-09

- **`data/` restructured.** Top-level task directories renamed:
  `dense_captioning/`, `event_verification/`, `pointing/`,
  `referring/`, `temporal_localization/`, `vqa/`. The legacy
  `Spatial/` directory was dropped.

## 2026-05-04

- **Initial release**: full release uploaded to
  `nvidia/PhysicalAI-VANTAGE-Bench` under `data/` (PR #2).
