# Changelog

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

## 2026-05-27
- **`data/pointing/VANTAGE_2DPointing.tsv` updated.** MCQ option
  coordinates (columns `A`–`D`) are now expressed in the normalized
  `0–1000` coordinate system (each cell is an `x,y` pair, with both
  components in `[0, 1000]` relative to the image dimensions). The
  public TSV ships only the question side: columns are
  `index, question_id, image_path, question, A, B, C, D`; the
  ground-truth fields (`answer`, `target_point`) are held server-side
  and are not included in the released file.
- **`data/event_verification/` flattened** to match the `vqa/` and
  `temporal_localization/` layout. The `filtered/.../{metropolis,tailgating,warehouse_near_miss}`
  subtree was removed; all 163 videos now live directly under
  `data/event_verification/videos/`, and the four annotation JSONs were
  moved + renamed to
  `data/event_verification/data_jsons/annotations/{metropolis_event_verification,tailgating_location_a,tailgating_location_b,warehouse_near_miss}.json`.
  Each `bcq[].video` is now the basename (e.g. `example.mp4`) and each
  `bcq[].id` is the stem (e.g. `example`); all other fields, entry
  order, and counts (163 total) are preserved. The `configs:` glob in
  the top-level README is updated accordingly.
- Renamed remaining active Metropolis-named annotation JSON artifacts to
  VANTAGE naming for public dataset consistency:
  `data/event_verification/data_jsons/annotations/metropolis_event_verification.json`
  → `data/event_verification/data_jsons/annotations/VANTAGE_EventVerification.json`;
  `data/vqa/data_jsons/annotations/Metropolis_VQA_Verification_Final_ITS_Data.json`
  → `data/vqa/data_jsons/annotations/VANTAGE_VQA_Verification_Final_ITS_Data.json`.
  File contents are unchanged; only filenames moved. The `configs:`
  globs in the top-level README already match the new filenames.
  `data/README.md` updated to reference the new event-verification
  filename.
- **`data/vqa/data_jsons/annotations/*.json` reduced to inference-oriented fields.**
  Each entry now carries exactly `{q_uid, question, options}`. The
  metadata fields `industry`, `event_type`, `start_time`, `end_time`,
  `video_duration`, `task_type`, and `dimension` were removed across all
  five files. Entry count (1,195) and values of the retained fields are
  unchanged. Smoke-tested against VLMEvalKit's `VANTAGE_VQA` inference
  preparation: TSV regeneration, prompt building, and video resolution
  all pass.
- **`data/temporal_localization/data_jsons/annotations/*.json` reduced
  to inference-oriented fields.** Each entry now carries exactly
  `{vid, question_id, question}` (key order preserved). The metadata
  fields `industry`, `event_type`, `task_type`, and `duration` were
  removed across all three files. Entry count (1,067) and values of the
  retained fields are unchanged; the 1,067 `question_id`s remain
  globally unique. Smoke-tested against VLMEvalKit's `VANTAGE_Temporal`
  inference preparation: TSV regeneration, prompt building, and video
  resolution all pass.
- Event Verification annotations were left unchanged in this pass; the
  current `data/event_verification/data_jsons/annotations/*.json`
  schema is treated as already inference-appropriate.

## 2026-05-19

- README YAML updated with a `configs:` block so the HF dataset viewer
  exposes one tab per task (`vqa`, `temporal_localization`,
  `event_verification`, `referring`, `pointing`, `tracking`, `2dbbox`,
  `dense_captioning`).
- Added `data/2dbbox/metadata.jsonl` and
  `data/dense_captioning/metadata.jsonl` so the image / video tasks are
  browsable in the viewer.

## 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).
