| # Working with agents: OLIVE FRP dataset |
|
|
| Orientation for an AI agent using this HuggingFace dataset (`ApocalyVec/olive-physio`). |
| See `README.md` (the dataset card) for full field docs. |
|
|
| ## Load it |
|
|
| ```python |
| from datasets import load_dataset |
| frp = load_dataset("ApocalyVec/olive-physio", "default") # fixation-locked FRP epochs |
| ern = load_dataset("ApocalyVec/olive-physio", "ern") # response-locked ERN epochs |
| ``` |
|
|
| Two configs: **`default`** (`data/frp_dataset.parquet`) and **`ern`** (`data/ern.parquet`). |
|
|
| ## Conventions an agent MUST respect |
|
|
| - **`y == 1` is the target**, `y == 0` non-target (default config). Targets are the minority |
| class (~40%). Do not assume `1`=non-target. |
| - **`task`** is a per-EPOCH label (`visual_search` = calibration blocks, `spaceshooter` = |
| gameplay blocks). Both occur within every study session; it is **not** a per-study field. |
| Filter by `task`, not by `user_study`, to separate the two tasks. |
| - **`p_target`** (default config) is a per-fixation implicit-evidence probability for |
| auditability / decoder-swap comparison; it is present for US2/US3 only (`NaN` for US1) and |
| is not the literal value used in the studies. |
| - **`condition`** (`IE`/`E`) is the as-published label; use it for anything that should agree |
| with the paper. `condition_ra` is an unresolved audit overlay; ignore it for paper-facing work. |
| - **ERN config**: `label` is `0`=correct (enemy hit) / `1`=error (friendly fire); epochs are |
| response-locked `[-200, 600] ms` @256 Hz (`[20, 205]`), 0.5 to 30 Hz filtered. |
| - `eeg` loads as a nested array; reshape a row via `np.array(row.tolist(), dtype=np.float32)` |
| → `[20, 230]` (default) / `[20, 205]` (ern). EEG is 256 Hz; FRP window is `[-0.1, 0.8] s`. |
| - `saccade_*` / `fixation_duration` are `NaN` by default (a separate opt-in derivation). |
| |
| ## Cohort & provenance |
| |
| 25 subjects (the OLIVE IE+E cohort with data). The paper describes the studies and the |
| implicit-evidence channel; this card does not duplicate that. Code + reproduction: |
