Hi all
I'm trying to train the neural networks with the NNScripts, but I don't know what to put in
the learning rate estimation list (lre.scp).
if someone could guide me...
thx
ana

The learning rate in gradient descent algorithm is being decreased
during training. The decrement is done if the classification accuracy
stops growing (< 0.5%). The accuracy is evaluated on a cross-validation
set very often. But any set can be used for this. For example, it is
better to use a training set if the cross-validation set is
non-representative or too small, not to step out of the "global" minimum
due to a bad estimation of the step length (learning rate).
