From: Claudia H Hofemann on 14 Apr 2010 03:48 Hi, I am working with a simple feed-forward network with the aim to compare the information content of four different datasets. Unfortunately is the output of the neural networks varying which makes it kind of hard to compare the different sets. My input data is divided by divideblock, so the reason can't be the random data division. I really hope that one of you out there has a good idea to solve this problem!! Thanks a lot in advance, Claudia

Hi Greg, thanks a lot for you tip, I wasn't even aware of the fact that I am generating random number ... Could you give me one more hint - how do I control those generators \ where do I find them ? thanks a lot in advance ... Claudia |
