27 Jul 2012 SLM - Shape Language Modeling Least squares spline modeling using shape primitives Author: John D'Errico

I find this whole idea of nonparametric "fitting" very intriguing, as I have some data for which I do not have a function to fit to the data. I have position vs. time data points, and I need to get the acceleration vs. time. I have found that different fit functions certainly have different derivative behaviors, so will SLM give a reliable fit that is twice differentiable? You indicate it gives the fit plus derivatives.

If this could work in a way I could have confidence in, it would be a godsend!
