[PDP-discuss] Higher error in test than train?

[Frank Leoné]

Hi all,

I'm experiencing a strange problem. After I have trained my network, it 
reaches an error of about 2, which is good enough. But if I then run a 
test-run (so without changing the weights) with the same data, the error is 
about the ten-fold. How can this be if it is exactly the same data?

Earlier I got an even higher error and when I then continued training the 
error rose really high, without going down anymore. This was because I had 
the send delta on in the train trial and not in the test-trial, which 
resulted in the properties of the neurons being changed (I think).

     kind regards,

             Frank
