class mlpack::ann::Subview< InputDataType, OutputDataType >

Implementation of the subview layer.

The subview layer modifies the input to a submatrix of required size.

Template Parameters

InputDataType	Type of the input data (arma::colvec, arma::mat, arma::sp_mat or arma::cube).
OutputDataType	Type of the output data (arma::colvec, arma::mat, arma::sp_mat or arma::cube).

Constructor & Destructor Documentation

Subview()

Subview ( const size_t  inSize = 1, const size_t  beginRow = 0, const size_t  endRow = 0, const size_t  beginCol = 0, const size_t  endCol = 0  )

inline

Create the Subview layer object using the specified range of input to accept.

Parameters

inSize	Width of sample.

Member Function Documentation

Backward()

void Backward ( arma::Mat< eT > &&  , arma::Mat< eT > &&  gy, arma::Mat< eT > &&  g  )

inline

Ordinary feed backward pass of a neural network, calculating the function f(x) by propagating x backwards trough f.

Using the results from the feed forward pass.

Parameters

input	The propagated input activation.
gy	The backpropagated error.
g	The calculated gradient.

Definition at line 130 of file subview.hpp.

Forward()

void Forward ( InputType &&  input, OutputType &&  output  )

inline

Ordinary feed forward pass of a neural network, evaluating the function f(x) by propagating the activity forward through f.

Parameters
