Tsinalis-2016 Embeddings

Pre-extracted per-epoch embeddings from TsinalisCNN (Tsinalis et al. 2016), trained on Sleep-EDF via PhysioEx.

Each subject directory contains:

embeddings.npy — (n_epochs, 500) per-epoch embeddings (bfloat16)
labels.npy — (n_epochs,) AASM sleep stage labels

Note: Tsinalis concatenates L=5 epochs before convolution. Embeddings are extracted using centered windows (each epoch gets the feature vector from the window centered on it).

Usage

from physioex.models import load_embeddings
path = load_embeddings("tsinalis-2016", "hmc", verbose=True)
