Em Learning Error

Post by xavier7179 »

Hello,

I'm tried to better handle your learning classes, so I wrote a program which can be basically summarized as:
  • open a network
  • generate a Dataset from the network
  • copy the original network in new one, also perturbing the CPT
  • run the EM algorithm on the copied/perturbed net.
I got the following message which has not much meaning to me: "EM: non-fixed deterministic and Noisy Adder nodes not supported".

What I got wrong?

Thanks,
Alessandro

It seems that your network has non-fixed deterministic and Noisy Adder nodes (which are not supported by EM algorithm). You should try other learning algorithm or modify your network to fit EM.
