Extended Data Fig. 9. Interpretability ratio of feature heatmaps.
Interpretability ratio of feature heatmaps - a) Two heatmap examples of a seizure snapshot of Patient_01 (NIH treated, ECoG, CC1, Engel I, ILAE 1) with the beta frequency band (left) and the neural fragility heatmap (right). Both colormaps show the relative feature value normalized across channels over time. The black line denotes electrographic seizure onset. (b) A box plot of the interpretability ratio that is defined in Results Section 8.12 computed for every feature. The y-axis shows an effect size difference between the interpretability ratios of success and failed outcomes. The interpretability ratio for each patient’s heatmap is defined as the ratio between the feature values in the two electrode sets (SOZ/SOZC). Neural fragility is significantly greater then the beta band (alpha level=0.05).
