In this paper, we propose an algorithm to improve the performance of the mu-law PNLMS algorithm (MPNLMS) for nonsparse impulse responses. Although the existing MPNLMS algorithm wa...

We propose a sparse non-negative image coding based on simulated annealing and matrix pseudo-inversion. We show that sparsity and non-negativity are both important to obtain part-...

We study trajectory inverse kinematics: to find a feasible trajectory in angle space that produces a given trajectory in workspace. We explicitly represent the multivalued invers...
