ANN performance using function
显示 更早的评论
I have produced an ANN that is predicting power output of wind turbines based on inputs. I have foudn the below function on mathworks site:
perform(net,t,y)
I ahve incorporated this in my code and it returns a value. My questions is what exactly does the number mean/reate to? Is there an 'ideal' value for this (ie. closeest to 0 is desirable)
Thanks

Hi,
The value perform function returns network performance calculated according to the net.performFcn and net.performParam property values which would differ on the train function you have used. You could check for these property values and get the used error performance metric.
For example
[x,t] = simplefit_dataset;
net = feedforwardnet(20);
net = train(net,x,t);
y = net(x);
perf = perform(net,t,y)
net.performFcn
net.performParam
