Neural Network Fitting Finding Desired points

Dear community;

First, very new to neural networks. That being said, I have used feedforwardnet() and train() to fit curves before. What I want to do not is to use a neural network to help me find specific points on the curve.

Imagine, I would like to find everytime, regardless of position or high that abrupt change (see image below). I know there are traditional ways to do that but I am interested in the neural network approach so I can apply it to other situations.

Thanks for your help.

Hi

Essentially the curve you shared is in the form of a sequential data starting from x=0.

Since you need to find point where there is an abrupt change, you can think of this problem as classifying time steps in a sequential data, where each time step would fall under two classes: Abrupt change or not.

You can refer, the following example to look at this approach in more detail.

Hope this helps.

Thanks
