Unlike regular polynomials, the Bernstein polynomials offer smooth fitting with no wild deviations that occur when the order of the fitting classical polynomial is high. I vaguely remember learning about Chebyshev polynomials for this purpose. As I recall, Chebyshev fits have the nice property of having a hard upper bound on the error, which is within a constant (a factor of about 3 IIRC) of the worst-case error of the optimal fit. I'd have to dig around to find that textbook, though, it may have been lost in the mists of time... |
