Signal classification - recognise a signal with AI

Question

I have a problem with recognising a signal. Let say the signal is a quasiperiodic signal, the period time has finite limits. The "shape" of the signal must match some criteria, so the actual algorithm using signal processing techniques such as filtering, derivating the the signal, looking for maximum and minimum values. It has a good rate at finding the good signals, but the problem is it also detects wrong shapes too.

So I want to use Aritifical Intelligence - mainly Neural Networks - to overcome this problem. I thought that a multi layer network with some average inputs (the signal can be reduced) and one output whould shows the "matching" from 0..1. However the problem is that I never did such a thing, so I am asking for help, how to achive something like this? How to teach the neural network to get the expected results? (let say I have vectors for inputs which should give 1 as output)

Or this whole idea is a wrong approximation for the problem? I am open to any learning algorithms or idea to learn and use to overcome on this problem.

So here is a figure on the measured signal(s) (values and time is not a concern now) and you can see a lot "wrong" ones, the most detected signals are good as mentioned above.

Answer 1

Your question can be answered in a broad manner. You should consider editing it to prevent it to be closed.

But anyway, Matlab had a lot of built-in function and toolbox to support Artificial Intelligence, with a lot of sample code available, which you can modify and refer to. You can find some in Matlab FileExchange.

And I know reading a lot of technical paper for Artificial Intelligence is a daunting task, so good luck!
