# EEGPT Pretrained Model
|
| 11 |
+
|
| 12 |
+
Pretrained EEGPT encoder weights for EEG signal processing from [EEGPT: Pretrained Transformer for Universal and Reliable Representation of EEG Signals](https://proceedings.neurips.cc/paper_files/paper/2024/file/4540d267eeec4e5dbd9dae9448f0b739-Paper-Conference.pdf).
|
| 13 |
+
|
| 14 |
+
This model was pretrained on a large-scale EEG dataset using masked dual self-supervised learning.
|
| 15 |
+
|
| 16 |
+
## Model Details

| 19 |
+
- **Embedding dimension:** 512
|
| 20 |
+
- **Number of attention heads:** 8
|
| 21 |
+
- **Patch size:** 64
|
| 22 |
+
- **Parameters:** ~10M
|
| 23 |
+
|

+
## Usage
|
| 25 |
+
|
| 26 |
+
```python
|
| 27 |
+
from braindecode.models import EEGPT
|
| 28 |
+
import mne
|
| 29 |
+
|
| 30 |
+
# Create channel info (example with 22 channels)
|
| 31 |
+
ch_names = ["Fz", "FC3", "FC1", "FCz", "FC2", "FC4", "C5", "C3", "C1", "Cz",
|
| 32 |
+
"C2", "C4", "C6", "CP3", "CP1", "CPz", "CP2", "CP4", "P1", "Pz", "P2", "POz"]
|
| 33 |
+
ch_types = ["eeg"] * len(ch_names)
|
| 34 |
+
info = mne.create_info(ch_names=ch_names, sfreq=250., ch_types=ch_types)
|
| 35 |
+
|
| 36 |
+
# Load pretrained model
|
| 37 |
+
model = EEGPT.from_pretrained(
|
| 38 |
+
"braindecode/eegpt-pretrained",
|
| 39 |
+
n_outputs=4, # number of classes for your task
|
| 40 |
+
n_chans=22,
|
| 41 |
+
n_times=1024,
|
| 42 |
+
chs_info=info["chs"],
|
| 43 |
+
sfreq=250.0
|
| 44 |
+
)
|
| 45 |
+
|
| 46 |
+
# Use for downstream tasks
|
| 47 |
+
# model can now be fine-tuned on your specific EEG classification task
|
