OpenMHC LSM2 (weekly)
Reference checkpoint for OpenMHC. Window: weekly (10080 minute, patch 60), 19 sensor channels.
An extension of LSM2-daily to 7-day (10080 minute) context. Same masked-autoencoder ViT architecture, but pre-trained on week-long sequences with a larger 60-minute patch size — useful when downstream tasks need multi-day context. Wrapped here for the OpenMHC imputation evaluation track.
Usage
from openmhc.imputers import LSM2Imputer
import openmhc
imp = LSM2Imputer.from_release("hf://MyHeartCounts/openmhc-lsm2-weekly")
results = openmhc.evaluate_imputation(imp, version="xs")
print(results.summary())
Requires the matching optional extras: pip install 'openmhc[lsm2,hf]'.
