PhysioEx — Pretrained Sleep Staging Models

Pretrained deep learning models for automatic sleep staging from PhysioEx (Gagliardi et al. 2025).

All models follow the AASM 5-class standard: W, N1, N2, N3, REM.

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

`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)
