Abstract

Principal curve pass through the middle of a multidimensional data set, to express the distributing shape of the points in the data set, we model principal curve for it. The new method of modeling the complex principal curve, based on B-spline network, is proposed. This method combines the polygonal line algorithm of learning principal curve with B-spline network. At one time, the algorithm finding a bifurcate point of the complex principal curve is presented. Our experimental results on simulate data demonstrate that it is feasible and effective.
