Parametric dictionaries can increase the ability of sparse representations to meaningfully capture and interpret the underlying signal information, such as encountered in biomedical problems. Given a mapping function from the atom parameter space to the actual atoms, we propose a sparse Bayesian framework for learning the atom parameters, because of its(More)
The phenomenon of Bose-Einstein condensates refers to a system of particles obeying the Bose statistics. In particular, under a critical temperature T c , a macroscopical number of particles (in analogy with their total number) share the same quantum state. Such a situation gives rise to fundamental physical phenomena as superfluidity in liquid helium and(More)
