众所周知且流行的Savitzky-Golay滤波器具有若干缺点。一个非常有吸引力的替代方案是基于惩罚最小二乘的平滑器，扩展了惠特克80年前提出的想法。这个平滑器非常快，可以连续控制平滑度，自动插值，并允许快速的留一交叉验证。它可以用几行Matlab代码编程。理论，实现和应用。
The well-known and popular Savitzky-Golay filter has several disadvantages. A very attractive alternative is a smoother based on penalized least squares, extending ideas presented by Whittaker 80 years ago. This smoother is extremely fast, gives continuous control over smoothness, interpolates automatically, and allows fast leave-one-out cross-validation. It can be programmed in a few lines of Matlab code. Theory, implementation, and applications are presented.
