Previous studies in automated screening have found a maximum accuracy of 92.6%. Methods: This work proposes a classification methodology based on efficient coding of the(More)
— In this paper, a method to design online optimal policies that encompasses Hamilton-Jacobi-Bellman (HJB) equation solution approximation and heuristic dynamic programming (HDP) approach is proposed. Recursive least squares (RLS) algorithms are developed to approximate the HJB equation solution that is supported by a sequence of greedy policies. The(More)
