Empirical Bayes Method for Boltzmann Machines
Muneki Yasuda, Tomoyuki Obuchi
In this study, we consider an empirical Bayes method for Boltzmann machines and propose an algorithm for it. The empirical Bayes method allows estimation of the values of the hyper…

Cross validation in sparse linear regression with piecewise continuous nonconvex penalties and its acceleration
Tomoyuki Obuchi, Ayaka Sakata
We investigate the signal reconstruction performance of sparse linear regression in the presence of noise when piecewise continuous nonconvex penalties are used. Among such penalti…

Perfect reconstruction of sparse signals with piecewise continuous nonconvex penalties and nonconvexity control
Ayaka Sakata, Tomoyuki Obuchi
We consider compressed sensing formulated as a minimization problem of nonconvex sparse penalties, Smoothly Clipped Absolute deviation (SCAD) and Minimax Concave Penalty (MCP). The…
