What is the most common approximation algorithm for sine function which can be implemented with self-organizing maps algorithm? I was thinking of least-squares approximation but I can't find a description of it for sine(or any trigonometrical) function.

0Can you just sample the sine function at evenly space points and get something piecewise-linear? Then your SOM has to approach this collection of lines. – 2012-09-27
