I'm currently doing a thesis using TDA. Excuse my shameless opportunism, but the topic I've come up with is using figure h [1] as a channel selection mechanism to select EEG channels [2]. I plan to then use a Gaussian process (similar to an SVM) to detect the time when a seizure occurs. From your position of expertise, can you see any major problems off the top of your head?
