摘要：The prefitting and backfitting methods are commonly used to sparsify the full solution of naive kernel minimum squared error. As known to us, the forward learning methods including prefitting and backfitting only assist us in finding the suboptimal solutions. To enhance the testing real time further, in this paper by virtue of the idea of incorporating the backward learning algorithm into the forward learning algorithm, two improved schemes on the basis of prefitting and backfitting are proposed. Compared with the original versions, two improved algorithms obtain fewer significant nodes, which indicates much better testing real time. Due to the addition of the backward learning to the forward learning, the proposed algorithms need more training computational costs. Investigations on benchmark data sets and a robot arm example are reported to demonstrate the improved effectiveness.
