Subject Re: Nightly Build fails occasionally
Date Wed, 07 Aug 2013 03:20:06 GMT
I am currently working on a refined version of NeuralNetwork (HAMA-770),
the new MLP will be implemented based on it. To quickly fix this problem
you mentioned, I will simply increase the training time to reduce the
chance of training failed.
