Detailed Description

The L1 loss is a loss function that measures the mean absolute error (MAE) between each element in the input x and target y.

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

L1Loss ( const bool mean = true )

Create the L1Loss object.

Parameters

mean	Reduction type. If true, it returns the mean of the loss. Else, it returns the sum.

Ordinary feed backward pass of a neural network.

Parameters

input	The propagated input activation.
target	The target vector.
output	The calculated error.

Computes the L1 Loss function.

Parameters

input	Input data used for evaluating the specified function.
target	The target vector.
