| # TriDrive — warning-probe label tables (`benchmark/labels/`) | |
| Human labels of **cabin moments** ("episodes") from the BATON naturalistic-driving corpus, used to train and evaluate the TriDrive | |
| current-state warning probe (development name CockpitWM, warning head W). Each row is one labelled episode anchored on one row of the | |
| 0.2 s analysis grid of the regime stratum it belongs to. Raters saw the cabin + road video around the onset `t0` and answered whether a | |
| warning to the driver was **warranted** at that moment. Nothing in these tables is derived from a driver-monitoring model. | |
| ## Files | |
| | file | rows | strata (manual / engaged) | warranted | drivers | use | | |
| |---|---|---|---|---|---| | |
| | `train_979.csv` | 979 | 562 / 417 | 182 | 91 | training labels of the warning probe (devices of the TRAIN split only) | | |
| | `gold_512.csv` | 512 | 329 / 183 | 63 | 47 | every anchored clean-test episode; column `in_gold_509` marks the headline rows | | |
| | `gold_509.csv` | 509 | 327 / 182 | 31 + 32 = 63 | 46 | **headline gold** of the paper (Section 4.4 / Appendix D) | | |
| | `counts.json` | — | — | — | — | every count measured while building these files, the assertions and the file checksums | | |
| ## Label definitions | |
| * **Episode / onset `t0`.** A candidate cabin moment of the annotation tool (route-relative seconds). The consensus protocol used two | |
| independent raters plus adjudication; only consensus rows are released (single-rater legacy rows, auto-excluded rows, `unsure` rows | |
| and the rows of two lenient rater groups are dropped). | |
| * **`label` / `y`.** `warranted` (y = 1): a warning to the driver was warranted at `t0` (attention or hands); `not_warranted` (y = 0). | |
| No `unsure` row is released. | |
| * **Anchoring rule** (s15 `gold_eval` rule): the episode is attached to the latest grid row of its route with | |
| `t in [t0 - 2.0, t0 + 0.2]`; routes without usable video are skipped; episodes whose route has no grid row in the window are not | |
| released (consensus TRAIN rows before anchoring: 1148; defined clean-test rows: 568). | |
| * **Stratum = anchored regime.** The grid exists separately for the *manual* regime (human drives) and the *engaged* regime | |
| (openpilot or OEM assistance active). An episode is looked up in both regimes' packs of its split; the row with the latest | |
| anchor wins, ties go to the regime of the episode itself. `stratum` therefore means "the regime pack whose row the episode is | |
| anchored on" (0 training and 0 gold episodes were anchorable in both; the regime at the anchor decides). | |
| * **Splits.** Devices (drivers) are assigned to train / val / test once for the whole project; `train_979.csv` contains only | |
| TRAIN-split devices, `gold_*.csv` only TEST-split devices. No device appears in both files. | |
| * **The 509 rule.** The evaluation grid compares the probe with the openpilot-derived comparators on the *same* rows: within a | |
| stratum it keeps the rows where every core comparator score is finite ("common finite comparator score" rule of the project's evaluation code, `warning_gold.py`, which is not part of this snapshot). Three of the 512 anchored rows fail it and are excluded from the headline numbers: | |
| * idx 137 — no legacy (seed-0) comparator row at all -> legacy comparator columns NaN -> outside the common-finite mask; | |
| * idx 38989 — legacy risk chain not anchored at the anchor row (risk_anchored = False); NaN comparator columns ['cockpit@3s', 'persist@3s', 'risk@3s'] -> outside the common-finite mask; | |
| * idx 6209 — legacy risk chain not anchored at the anchor row (risk_anchored = False); NaN comparator columns ['cockpit@3s', 'persist@3s', 'risk@3s'] -> outside the common-finite mask. | |
| All three are `not_warranted` (two manual, one engaged); the 512-row file keeps them with `in_gold_509 = False`. | |
| ## Columns | |
| | column | meaning | | |
| |---|---| | |
| | `idx` | episode id of the annotation tool (stable across every file of this bucket, e.g. `human_eval_299/manifest_v1.csv:s15_idx`) | | |
| | `uid` | pseudonymised route-segment group `driver_N__route_M__route_a-b` (`route_a-b` = segment range of the original recording) | | |
| | `driver` | pseudonymised device `driver_N` (one device = one driver = one vehicle) | | |
| | `stratum` | `manual` or `engaged`: the regime pack whose grid row the episode is anchored on (see above) | | |
| | `split` | device split of the row: `train` (train_979) or `test` (gold_512 / gold_509) | | |
| | `row` | 0-based row index of the anchor within the 0.2 s anchor grid of (`stratum`, `split`) — the row order of the released grid packs under `../../data/` (see `../../data/README.md`) | | |
| | `t0` | onset of the episode, route-relative seconds | | |
| | `t_anchor` | time of the anchored grid row, route-relative seconds (`t0 - 2.0 <= t_anchor <= t0 + 0.2`) | | |
| | `label` | `warranted` / `not_warranted` | | |
| | `y` | 1 if `label == warranted` else 0 | | |
| | `in_gold_509` | (gold_512 only) `True` for the 509 headline rows | | |
| ## Identifiers | |
| `uid` and `driver` are pseudonyms shared by every file in this bucket and by the public BATON release; the raw device ids, the | |
| recording timestamps and the annotators' identities were removed. Group / protocol / free-text columns of the annotation store are | |
| not released. | |
