Data Driven Adaptive Spline Smoothing

  title={Data Driven Adaptive Spline Smoothing},
  author={Ziyue Liu and Wensheng Guo},
In classical smoothing splines, the smoothness is controlled by a single smoothing parameter that penalizes the roughness uniformly across the whole domain. Adaptive smoothing splines extend this framework to allow the smoothing parameter to change in the domain, adapting to the change of roughness. In this article we propose a data driven method to… CONTINUE READING
