Suppose I have handwritten graph of some function, and what I want is to have some ML algorithm that find some simple function (in form of a string like “f(x) = 2 cos(x) + log(x)^2”) that fit my graph as well as possible. I tried to make something like this myself and find out that this task is surprisingly difficult, unless the function is trivial. Although I’m not a researcher, so maybe I just have lack of knowledge to crack this problem. I wonder if there any research papers relative to simiar problems. Or any suggestions how to approach this will be helpful as well.
