autoencoder_Ninput=100_Nhidden=25_rho=1e-2: A trained autoencoder example with 25 hidden units

Description Usage Format Examples

Description

autoencoder.object is an example object of class autoencoder containing the weights, biases and other parameter of a sparse autoencoder with N.input=100, N.hidden=25, with sparsity parameter rho=0.01, trained on a dataset of 5000 image patches of 10 by 10 pixels, randomly cropped from decoloured nature photos.

Usage

1
data('autoencoder_Ninput=100_Nhidden=25_rho=1e-2')

## Load a pre-trained autoencoder object with N.input=100 and N.hidden=5*5,
## trained on unlabeled set of 5000 image patches of size Nx.patch by Ny.patch, 
## randomly picked from 10 nature photos, and visualize the features 
## learned by its hidden units:

data('autoencoder_Ninput=100_Nhidden=25_rho=1e-2')

## Visualize hidden units' learned features:
visualize.hidden.units(autoencoder.object,Nx.patch=10,Ny.patch=10)
