This research aims to establish a reproducible method for differentiating labor from pregnancy using electrohysterography data.
Utilized the Icelandic 16-electrode EHG Database for multichannel recordings.
Signals were processed with detrending, band-pass filtering, and downsampling.
Divided recordings into non-overlapping 60-second windows to extract six key features.
Applied a cost-sensitive Random Forest model using 5-fold cross-validation with adjusted decision thresholds.
The model achieved an AUROC of 0.759 and an AUPRC of 0.319.
Recorded recall of 60.7% and specificity of 79.2% at the calibrated point.
Demonstrated effectiveness of fixed-window features for labor triage.
