The goal is to achieve the highest accuracy for a specific combination of the input variables. For example, I only evaluated three different combinations of the input, while we have other combinations like y=f(x1,x4), y=f(x3,x4,x5), y=f(x3), and so on.
As you know evaluation of all possible combinations is time-consuming. Is there any way to get the best combination of inputs?
Any help would be greatly appreciated.
We might need a bit more information about what you're trying to do here.
Is this a very generic ML question about grooming the input forms? If that's the case there is no simple answer, domain knowledge will be a great help, but I'd suggest a search for one of the many tutorials on this area on ML sites or youtube.
If that's not the case, we need more info about the problem you're trying to solve.
