Witryna11 kwi 2024 · Aiming at the problem of sparse measurement points due to test conditions in engineering, a smoothing method based on zero-padding in the wavenumber domain is proposed to increase data density. Firstly, the principle of data extension and smoothing is introduced. The core idea of this principle is to extend the discrete data … Witryna13 sty 2004 · However, the GCV score (not shown) has some local minima around the global minimum. As mentioned earlier, the smoothing spline regression is a linear estimate of the data and can be severely affected by outliers.
