For me, wealth management means more than providing my clients with investment advice. The Earth Mover's Distance (EMD) was introduced by Rubner, Tomasi and Guidbas [9] to measure the similarity between bags of vectors. It turns out that the Normalized Cuts algorithm of Shi and Malik (1), originally presented as a graph-theoretic algorithm, can be interpreted as such an algorithm. Most differential trackers compute motion only relative to one previous frame, accumulating errors indefinitely. Hospitals identify the type of coronary artery bypass graft (CABG) surgery admission as routine, urgent, or emergency, and identify CABG admissions as elective, from another hospital, from a long-term healthcare facility, and an admission that results from an emergency room visit.
