The authors propose a variant of the nonlinear conjugate gradient method for solving the tensor completion problem that employs the framework Riemannian optimization techniques on the manifold of tensors of fixed multilinear rank. Some preliminary numerical results are reported to investigate the effectiveness of the proposed algorithm.
