想知道一下哪些参数会影响smoothing的结果
比如fd,还有就是后面的data symbol的估计准确性等等。

introducing forgeting factor hurts the performance if fd = 0, intuitively ..
. but if fd is not zero, forgeting factor may improves or degrades the
performance, still intuitively ... smoothing should have the same effect ..
by the way, you do realize that you are implementing a LS algorithm that is
not optimal if the fd is known or has a known distribution?

曲线是光滑流形
但函数就是不SMOOTH,换了坐标就不是这个函数了

All following are in the paper:
D. Gottlieb, M.Y. Hussaini and S.A. Orzag, 1984
Theory and application of spectral methods.
(SIAM-CBMS, Philadelphia, PA, 1984) pp 1-94.
Given a smooth function f(x), to get its upto n-degree
polynomials interpolation.
Assume domain : [-1,1],
take Xj= cos(j*pi/n) as the interpolation points.
take Tj(x)=cos( j* acos(x)) as the n+1 basis.
Note Tj is just j-degree polynomial.
let f_n = A0*T0 + ... + An*Tn, then by definition of interpolation
A0*T0(X0) + ...

The plot of data shows the irregular upward trend in 2008-12.
I would like to draw a smooth line across my data points.
Any suggestion would be greatly appreciated!!!!!!
