getDropoutMask

A instance of the class <code><a href="/link/?package=darch&version=0.12.0" darch'="" data-mini-rdoc="darch::"></a>'>DArch</code>.

darch

Layer index or 0 for input dropout mask.

The dropout mask is applied to the weights between layer i and i+1, for 0 &lt; i
&lt; numLayers. For i = 0, the dropout mask for the input layer is returned,
which will be applied to the initial input data.

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 (2006) <DOI:10.1162/neco.2006.18.7.1527>) and "Reducing the
dimensionality of data with neural networks" (G. E. Hinton, R. R.
Salakhutdinov (2006) <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.
