| # AI4Sci brain-computer-interface decoding: public tracks |
|
|
| Prepared data for three of the five tracks of the `brain-computer-interface-decoding` task in |
| [T0-RSI/ai4sci-tasks](https://github.com/T0-RSI/ai4sci-tasks) and |
| [sunnweiwei/science-speedrun](https://github.com/sunnweiwei/science-speedrun). Each was built by |
| the task's `environment/data/materialize.py` from pinned public sources: |
|
|
| | track | source | classes | shape (channels, seconds, 200 Hz) | train / val / test windows | |
| | --- | --- | --- | --- | --- | |
| | `ad65` | [OpenNeuro ds004504](https://openneuro.org/datasets/ds004504) derivatives (CC0) | 3: Alzheimer's, frontotemporal dementia, control | 19 × 10 × 200 | 3,774 / 1,343 / 1,376 | |
| | `openbmi` | [GigaDB 100542](https://gigadb.org/dataset/100542) motor-imagery sessions (CC0) | 2: left, right | 62 × 4 × 200 | 12,800 / 4,400 / 4,400 | |
| | `longitudinal` | [OpenNeuro ds007176](https://openneuro.org/datasets/ds007176) (CC0) | 2: eyes closed, open | 58 × 2 × 200 | 28,523 / 8,418 / 10,028 | |
|
|
| Subjects are split with seed 3407 (test 20%, then validation 25% of the rest; AD65 stratified by |
| diagnosis); every session stays with its subject. Arrays are float32 microvolts in NumPy shards. |
|
|
| ```text |
| runtime/development/<track>/{train,val}/ manifest.json (id, label, subject, session, path, index), shards |
| runtime/private/<track>/public/ test inputs: manifest without labels, shards in random order |
| runtime/private/<track>/truth.jsonl test labels, subjects and sessions (verifier only) |
| records/<track>/ subject splits, preprocessing statistics, build receipt |
| release-manifest.json size and SHA-256 of every file |
| ``` |
|
|
| The FACED and TUEV tracks are not redistributable and come from a separate controlled-access |
| release. The task's `environment/data/materialize.sh release ROOT` installs all five tracks and |
| verifies every file against `release-manifest.json`. Only `runtime/development` may be mounted |
| into an agent's workspace; `runtime/private` is for the verifier. |
