wav2sleep

Cardio-respiratory sleep staging (4-class: Wake, Light, Deep, REM)

Model Description

This is a wav2sleep model for automatic sleep stage classification from cardio-respiratory signals (ECG, PPG, respiratory). wav2sleep is a unified multi-modal deep learning approach that can process various combinations of physiological signals for sleep staging.

Usage

from wav2sleep import load_model

# Load model from Hugging Face Hub
model = load_model("hf://joncarter/wav2sleep")

# Or load from local checkpoint
model = load_model("/path/to/checkpoint")

For inference on new data:

from wav2sleep import load_model, predict_on_folder

model = load_model("hf://joncarter/wav2sleep")
predict_on_folder(
    input_folder="/path/to/edf_files",
    output_folder="/path/to/predictions",
    model=model,
)

Training Data

The model was trained on polysomnography data from multiple publicly available datasets managed by the National Sleep Research Resource (NSRR).
