getDropoutMasks

A instance of the class <code><a href="/link/?package=darch&version=0.10.0" darch'="" data-mini-rdoc="darch::"></a>'>DArch</code>.

darch

Only available during fine-tuning, returns an empty list otherwise. Unlike
<a rd-options="" href="/link/getDropoutMask?package=darch&version=0.10.0" data-mini-rdoc="darch::getDropoutMask">getDropoutMask</a>, this list is 1-based, starting with the
dropout mask for the input layer at index 1. So <code>getDropoutMask(darch,
0)</code> returns the same as <code>getDropoutMasks(darch)[[1]]</code>.

The darch package is built on the basis of the code from G. E.
Hinton and R. R. Salakhutdinov (available under Matlab Code for deep belief
nets). This package is for generating neural networks with many layers (deep
architectures) and train them with the method introduced by the publications
"A fast learning algorithm for deep belief nets" (G. E. Hinton, S. Osindero,
Y. W. Teh; doi: 10.1162/neco.2006.18.7.1527) and "Reducing the
dimensionality of data with neural networks" (G. E. Hinton, R. R.
Salakhutdinov; doi: 10.1126/science.1127647). This method includes a pre
training with the contrastive divergence method published by G.E Hinton
(2002; doi: 10.1162/089976602760128018) and a fine tuning with common known
training algorithms like backpropagation or conjugate gradients.
Additionally, supervised fine-tuning can be enhanced with maxout and
dropout, two recently developed techniques to improve fine-tuning for deep
learning.
