I'm having lots of problems with my neural network. This is the error i get and my code.
Please help.

Check if "network" is null.

[Webuser]

provide us the object code

NeuralDataSet traindata = new BasicNeuralDataSet(netinput, netideal);

[JosAH]

provide us the object code

No, the exception stack trace showed this:

at neural_network.NetworkTrain.training(NetworkTrain. java:35)

so the OP'd better show us line 35 of the file NetworkTrain.java, because that line is on the track where the exception occurred; don't obfuscate people by writing nonsense and please don't beg for rep points, that is so adolescent. You haven't supplied (m)any useful answers yet.

kind regards,

Since the actual exception is thrown from:
at org.encog.neural.networks.training.propagation.bac k.Backpropagation.<init>(Unknown Source)

and the only line doing an init on Backpropagation is:
final Train train = new Backpropagation(network, traindata, 0.7, 0.2);

I would guess that that's line 35, so either network or traindata is null, and traindata is initialised two lines beforehand...

Of course, it could be some other internal thing to Backpropagation, but I would lay odds on it being network is null.
