I'm new in NN stuff and I've got a problem.
I want to project a neural network which can estimate amplitudes and frequencies of periodic signal with additional noise. This signal is a sum of 2-4 sine waves (+noise). I tried to solve it in several ways but nothing works. Maybe can you give me any advice, what should I give to input, and what kind of array/matrix I need to put on target output? What kind of network should it be? I tried to put on output every single A*sin(2*pi*f*t) but on training data - that works, on testing data - definitely no.
I will be so grateful for every advice! Hope you can help me! :) Thank you.
