Can I still use Gradient Descend as the optimizer?
I look through the code and find that the optimizer is set to LBFGS by
default. And there is no code for Gradient Descend optimizer.
If I want to use gradient descend as the optimizer, how to change the code?
By replace
` private val optimizer = new LBFGS(gradient, updater).`
with ` private val optimizer = new GradientDescend(gradient, updater)`?
Thank you for your reply :)
