Model Card for REVE-base
<!-- Provide a quick summary of what the model is/does. -->
REVE (project page here) is a transformer-based foundation model for EEG signal processing. It was trained on 60k hours of EEG data from various sources and is designed to be adaptable to any electrode configuration and a wide range of EEG-based tasks.
Model Details
Architecture
<!-- Provide a longer summary of what this model is. -->
REVE (Representation for EEG with Versatile Embeddings), a pretrained encoder explicitly designed to generalize across diverse EEG signals. REVE introduces a novel 4D positional encoding scheme that enables it to process signals of arbitrary length and electrode arrangement. Using a masked autoencoding objective, we pretrain REVE on over 60,000 hours of EEG data from 92 datasets spanning 25,000 subjects.

Uses
Example script to extract embeddings with REVE, using our position bank:
from transformers import AutoModel
pos_bank = AutoModel.from_pretrained("brain-bzh/reve-positions", trust_remote_code=True)
model = AutoModel.from_pretrained("brain-bzh/reve-base", trust_remote_code=True)
eeg_data = ... # EEG data as a torch Tensor (batch_size, channels, time_points), must be sampled at 200 Hz
electrode_names = [...] # List of electrode names corresponding to the channels in eeg_data
positions = pos_bank(electrode_names) # Get positions (channels, 3)
# Expand the positions vector to match the batch size
positions = positions.expand(eeg_data.size(0), -1, -1) # (batch_size, channels, 3)
output = model(eeg_data, positions)License and Responsible Use
