Neural network error plot


I am wondering if anybody could tell me how the neural network's error plot is calculated. I understand that the error term is recalculated in each iteration, but what is the actual formula used to calculate the error. 



Hi everyone, 

Please could I have a reply on this please? I couldn't find the answer in any of KNIME documentation




I don't know anything about the internals, but there are two possibilities to find out more:

  • The node descriptions often mention some papers that you might want to look into
  • If all else fails, you can always look into the source code. There you can find not only the actual algorithms, but often also some more documentation.

Hope that helps.

Thanks Marlin

Hello, did anyone receive or find an answer to this ?

what is the value of the error plot if we do not know what it should represent ?
