| # BCICIV-2a EEG Motor Imagery |
|
|
| ## Provenance |
|
|
| This repository contains one consolidated CSV shard derived from the local |
| research copy identified as the Kaggle dataset |
| [`aymanmostafa11/eeg-motor-imagery-bciciv-2a`](https://www.kaggle.com/datasets/aymanmostafa11/eeg-motor-imagery-bciciv-2a), |
| which describes the BCI Competition IV 2a motor-imagery recordings associated |
| with the Graz BCI laboratory. The uploader has represented that they have the |
| right to redistribute this research copy. The repository owner must preserve |
| any upstream attribution and terms that apply to the source dataset. |
|
|
| This card does not assert a SPDX license. `license: other` is intentional until |
| the upstream terms are independently mapped to a recognized license identifier. |
|
|
| ## Contents |
|
|
| - `BCICIV_2a_all_patients.csv` |
| - 2,448 epochs from 9 subject identities |
| - 22 EEG channels per epoch |
| - 201 samples per epoch at 250 Hz |
| - labels: `left`, `right`, `foot`, `tongue` |
| - identity fields: `patient` (subject) and `epoch` (session boundary) |
|
|
| The CSV is a tabular, already-windowed representation. It must not be pooled |
| with Brennan, D01, Chisco, D09, or SparrKULee. |
|
|
| ## Intended use |
|
|
| Research and reproducibility testing for the THINKING EEG pipeline, including |
| schema validation, checksum verification, leakage-safe subject/session splits, |
| and controlled training experiments. |
|
|
| ## Limitations and safety |
|
|
| - This dataset is not a clinical diagnostic resource. |
| - The scientific gate for the current BCICIV-2a encoder is **false**; no |
| deployability or scientific headline is claimed by this repository. |
| - Do not infer identity beyond the explicit `patient` and `epoch` fields. |
| - Do not use random epoch splits for scientific evaluation. |
| - Consumers must verify the immutable catalog revision and shard SHA-256 before |
| training. |
| - The repository contains EEG-derived human-subject data. Users are responsible |
| for complying with the source terms, applicable law, institutional review |
| requirements, and any restrictions imposed by the data custodian. |
|
|
| ## Integrity |
|
|
| Measured source shard: |
|
|
| - bytes: `214848010` |
| - SHA-256: `fa52c442278b63c9add50939b453f0668719ff1137dd596b5b1cac90fe3aa6cd` |
|
|
| The GitHub catalog must pin the actual 40-character Hugging Face commit SHA; |
| `main` and other moving revisions are not valid for scientific runs. |
|
|
| ## Citation and attribution |
|
|
| Cite the original BCI Competition IV 2a dataset and the upstream Kaggle source |
| when using this derived tabular copy. Do not represent this repository as the |
| original competition distribution. |
|
|
| ## Release status |
|
|
| `gate_pass: false` for the current scientific evaluation. This publication |
| provides versioned data access only; it does not certify model quality or |
| clinical/deployment readiness. |
