# Submission Format

A submission is a single JSON file (`.json`) containing a top-level array of 500 prediction objects — one per question.

## Schema

```json
[
  {"example_id": 1,   "predicted_answer": "A"},
  {"example_id": 2,   "predicted_answer": "C"},
  {"example_id": 500, "predicted_answer": "B"}
]
```

**Required keys (per object):**
- `example_id` — integer in `[1, 500]`, matching `example_id` in `annotations_public.json`.
- `predicted_answer` — single uppercase letter that appears in that question's `options` dict.

**Important:** questions have **between 4 and 10 options**. The valid answer letters for any given question are exactly the keys of its `options` dict. Most are A-F; Event Ordering questions can extend to A-J. A letter outside the question's option set is rejected.

**Optional keys (ignored, but useful for your own debugging):** `raw_response`, `confidence`, `tokens`, etc.

## Rules

1. Top-level must be a JSON array (not an object).
2. The submission must cover **exactly 500 unique `example_id`s**, one per question.
3. Duplicate `example_id`s are rejected.
4. Letters must be uppercase (whitespace is trimmed).
5. File extension must be `.json`.

## Converting from existing eval-script output

The reference inference scripts in the [EgoMemReason GitHub repo](https://github.com/Ziyang412/EgoMemReason) write a list of records with a `pred` field. One-liner to convert:

```python
import json
src = json.load(open("results_my_model.json"))
sub = [{"example_id": r["example_id"], "predicted_answer": r["pred"]} for r in src]
json.dump(sub, open("submission.json", "w"))
```

## How submissions are scored

Accuracy (%) for each of the six `query_type` splits:

- Cumulative State Tracking (100 Qs)
- Temporal Counting (100 Qs)
- Event Ordering (100 Qs)
- Event Linking (100 Qs)
- Spatial Preference (50 Qs)
- Activity Pattern (50 Qs)

plus **Overall** accuracy on all 500. All seven values appear on the leaderboard; ranking is by Overall descending.

## Submission limits

- **5 submissions per HF user per 24-hour window.**
- The 24-hour window is rolling, not midnight-aligned.

## Selected submission

Submit as many times as you like under the cap. In the **Manage my submissions** tab you can mark **one** of your past submissions as your *selected* entry. The default leaderboard view shows only each team's selected entry; the "Show all submissions" toggle reveals all.

## Required metadata fields

When you submit you must fill in:

| Field | Required | Notes |

| `team_name` | yes | Team or affiliation |
| `method_name` | yes | Short title displayed on the leaderboard |
| `uses_external_data` | yes (yes/no) | Did you train / finetune on anything beyond EgoLife? |
| `uses_video_frames` | yes | one of `frames-only` · `video-only` · `frames+audio` · `captions-only` · `other` |
| `model_size` | no | e.g. `8B`, `32B`, `API` |
| `method_description` | no | Free-form description |
| `project_url` | no | Project page |
| `publication_url` | no | arXiv / OpenReview link |
