Doing a non-map-reduce neural network in Mahout would be of substantial interest. I don't see a role for something that is 10x slower than it should be. On Tue, Feb 25, 2014 at 10:03 AM, Maciej Mazur wrote: > I understand that neural networks aren't perfectly suitable for MapReduce. > But if th

I understand that neural networks aren't perfectly suitable for MapReduce. But if there is very large network and lagre training set it seems to be a good solution to use MapReduce. RBMs and Autoencoders are used for pretraining. It allows to learn better representation for deep architectures (ac

Since the training methods for neural network largely requires a lot of iterations, it is not perfect suitable to implement it in MapReduce style. Currently, the NeuralNetwork is implemented as an online learning model and the training is conducted via stochastic gradient descent. Moreover, curre
