Example hourly forecasts showing high, medium, and low risk states, and medium and high risk thresholds. Predicted seizure likelihood (black line) derived from the hourly forecaster for P4 from the end of September to the end of January. Seizures are marked with red triangles. High, medium and low risk states are indicated by the red, orange and green regions, respectively, and are separated by the medium and high risk thresholds. Note that the medium risk and high risk thresholds—indicated by the orange and red lines, respectively—can change after weekly retraining. The cyclical seizure likelihood is mostly attributable to multiday heart rate cycles.
