# REVE: results on public EEG datasets

Foundation model

REVE is a pretrained EEG encoder released in Small, Base and Large sizes, all trained on one corpus that its paper's appendix lists: public collections from TUH, PhysioNet, OpenNeuro and MOABB among others, with the recordings of the authors' own downstream tasks removed. BCI Report ran the Base and Large checkpoints frozen, with the published ridge head; their input removes each segment's per-channel mean, a deviation declared before scoring. The weights are under the REVE Responsible Use License, accepted for this site on 4 October 2026.

## Checkpoints, inputs and terms

What was run, as the v9 release records it: each checkpoint’s revision and SHA-256, its encoder parameters, the footnote its rows carry and its weights licence. No weights, adapted weights or LoRA deltas were kept or shared, and no endorsement by the model’s authors is implied.

### REVE Base

- Panel: A row beside the core matrix on every protocol page
- Encoder parameters: 69.19M
- Revision: `brain-bzh/reve-base @ dc2a075c`
- Checkpoint SHA-256: `8ecc650619598748286c2457f81f5c6bd12e8bb59db44f7b02af1955c44de8fe`
- Paper: [paper ↗](https://arxiv.org/abs/2510.21585)
- Weights licence: REVE Responsible Use License v1.0 (owner-approved 2026-10-04)
- Licence note: REVE Responsible Use License v1.0: aggregate scientific results only; no re-identification, model inversion, membership inference or non-consensual profiling; cite the REVE paper and name the model version; no adapted weights shared.
- Rights review: Accepted by the owner on 2026-10-04. Aggregate scientific results only; no re-identification, model inversion, membership inference or non-consensual profiling; the REVE paper is cited and the model version named; no adapted weights are shared.
- Row footnote: Input removes the per-segment per-channel mean before the published /100 scaling (declared before scoring); a no-mean-removal sensitivity run scores P300 0.71 percentage points higher and sleep 1.40 lower.
- Notes: REVE input removes the per-segment per-channel mean (declared before scoring; the published LaBraM/CBraMod rows did not); a no-mean-removal sensitivity run is stated in the row footnote.
- EEGMAT adaptation: Run: a head trained on the frozen encoder against LoRA rank 4, three seeds.

### REVE Large

- Panel: A row beside the core matrix on every protocol page
- Encoder parameters: 389.98M
- Revision: `brain-bzh/reve-large @ 317531c7`

- Licence note: REVE Responsible Use License v1.0 (as REVE Base).
- Rights review: Accepted by the owner on 2026-10-04. Aggregate scientific results only; no re-identification, model inversion, membership inference or non-consensual profiling; the REVE paper is cited and the model version named; no adapted weights are shared.
- Row footnote: Input removes the per-segment per-channel mean (declared before scoring); the no-mean-removal sensitivity run scores P300 2.06 percentage points lower and sleep 0.93 lower.
- Notes: REVE input removes the per-segment per-channel mean (declared before scoring); a no-mean-removal sensitivity run is stated in the row footnote.
- EEGMAT adaptation: Run: a head trained on the frozen encoder against LoRA rank 4, three seeds.

## Pretraining exposure, by dataset

Whether each core dataset is in the model authors’ published pretraining list, checked on 2026-10-04 and linked to the source. A dataset absent from the list is not proof that its recordings were never seen; recording-level audits were not done.

**Note on the check:** REVE's Table 7 counts 27 MOABB datasets but names 25 (26 with the open-subset card); the unnamed slot cannot be BETA or ds005342 because MOABB added those loaders only in March 2026.
