In this paper, we tackle the problem of measuring similarity among graphs that represent real objects with noisy data. To account for noise, we relax the definition of similarity using the maximum weighted co-k-plex relaxation method, which allows dissimilarities among graphs up to a predetermined level. We then formulate the problem as a novel quadratic(More)
Quantum annealing is a promising technique which leverages quantum mechanics to solve hard optimization problems. Considerable progress has been made in the development of a physical quantum annealer, motivating the study of methods to enhance the efficiency of such a solver. In this work, we present a quantum annealing approach to measure similarity among(More)

Attention Deficit Disorder (ADD) could be considered a clinically heterogeneous condition that involves three sets of symptoms: inattention, impulsive behaviors, hyperactivity or a combination of them. Magnetic Resonance Imaging (MRI) has demonstrated size changes at cerebellum and basal ganglia of ADD in comparison with healthy child. The purpose of our(More)
