Process of searching for the preictal interval. Each example of the six data distribution categories is represented by the projected UMAP components (labelled x, y, and z). The seizure occurs at 0 min. Category 1 was obtained from patient 21902, seizure 4, reduced multivariate features. Category 2 was obtained from patient 98102, seizure 5, reduced univariate nonlinear features. Category 3 was obtained from patient 58602, seizure 4, reduced multivariate features. Category 4 was obtained from patient 110602, seizure 3, reduced univariate linear features. Category 5 was obtained from patient 98202, seizure 2, reduced univariate nonlinear features. Category 6 was obtained from patient 123902, seizure 2, reduced univariate linear features.
