# PhysioEx — Pretrained Sleep Staging Models
Pretrained deep learning models for automatic sleep staging from [PhysioEx](https://github.com/guidogagl/physioex) (Gagliardi et al. 2025).
All models follow the AASM 5-class standard: **W, N1, N2, N3, REM**.
## Available Models
| Model | Architecture | Training Dataset | ACC | F1 | κ | Params | Reference |
|---|---|---|---|---|---|---|---|
| `sleeptransformer-phan` | Transformer | SHHS | **0.866** | **0.796** | **0.810** | 2.1M | Phan et al. 2022 |
| `tinysleepnet-supratak` | CNN + LSTM | Sleep-EDF | 0.842 | 0.790 | 0.784 | 83K | Supratak & Guo 2020 |
| `seqsleepnet-phan` | BiLSTM + Attention | Sleep-EDF | 0.810 | 0.758 | 0.742 | 659K | Phan et al. 2019 |
| `chambon2018` | Braindecode CNN | MASS SS3 | 0.826 | 0.731 | 0.736 | 29K | Chambon et al. 2018 |
| `tsinalis-2016` | 2-layer CNN | Sleep-EDF | 0.773 | 0.661 | 0.683 | 145K | Tsinalis et al. 2016 |
## Usage
```python
from physioex.models import load_from_pretrained
model = load_from_pretrained("sleeptransformer-phan", verbose=True)
# Extract or download embeddings
from physioex.models import load_embeddings
path = load_embeddings("sleeptransformer-phan", "hmc", verbose=True)
```
