Edited: (1) The following link explains expressivity and generalization power in machine learning: https://blog.evjang.com/2017/11/exp-train-gen.html
So my question is whether the superformula constitute an example of great expressivity and powerful generalization for curve fitting by using machine learning models.
Edited: (2) In the following link they use the superformula, Automatic Generation of Smooth Curves from Interpretable Low-Dimensional Parameters.
So the intuition seems fruitful. https://arxiv.org/pdf/1808.08871.pdf
Looks like six to me:
m, n1, n2, n3, a, b.
