Bilinear Interpolation is an mathematical technique, primarily used for scaling purposes. It is an extension of linear interpolation, for interpolating functions of two variables on a rectangular grid. The key idea is to perform linear interpolation first in one direction (e.\+g., along x-\/axis), and then again in the other direction (i.\+e., y-\/axis), on four different known points in the grid. This way, we represent any arbitrary point, present within the grid, as a function of those four points. \begin{DoxyTemplParams}{Template Parameters} {\em Input\+Data\+Type} & Type of the input data (arma\+::colvec, arma\+::mat, arma\+::sp\+\_\+mat or arma\+::cube). \\ \hline {\em Output\+Data\+Type} & Type of the output data (arma\+::colvec, arma\+::mat, arma\+::sp\+\_\+mat or arma\+::cube). \\ \hline \end{DoxyTemplParams} Definition at line 39 of file bilinear\+\_\+interpolation.\+hpp. \subsection{Constructor \& Destructor Documentation} \mbox{\label{classmlpack_1_1ann_1_1BilinearInterpolation_a8373b0b3b099c636a8e438baadfa3baf}} \index{mlpack\+::ann\+::\+Bilinear\+Interpolation@{mlpack\+::ann\+::\+Bilinear\+Interpolation}!Bilinear\+Interpolation@{Bilinear\+Interpolation}} \index{Bilinear\+Interpolation@{Bilinear\+Interpolation}!mlpack\+::ann\+::\+Bilinear\+Interpolation@{mlpack\+::ann\+::\+Bilinear\+Interpolation}} \subsubsection{Bilinear\+Interpolation()\hspace{0.1cm}{\footnotesize\ttfamily [1/2]}} {\footnotesize\ttfamily \textbf{ Bilinear\+Interpolation} (\begin{DoxyParamCaption}{ }\end{DoxyParamCaption})} Create the Bilinear Interpolation object. \mbox{\label{classmlpack_1_1ann_1_1BilinearInterpolation_ad384fa6deb9134484dea8961a70df35f}} \index{mlpack\+::ann\+::\+Bilinear\+Interpolation@{mlpack\+::ann\+::\+Bilinear\+Interpolation}!Bilinear\+Interpolation@{Bilinear\+Interpolation}} \index{Bilinear\+Interpolation@{Bilinear\+Interpolation}!mlpack\+::ann\+::\+Bilinear\+Interpolation@{mlpack\+::ann\+::\+Bilinear\+Interpolation}} \subsubsection{Bilinear\+Interpolation()\hspace{0.1cm}{\footnotesize\ttfamily [2/2]}} {\footnotesize\ttfamily \textbf{ Bilinear\+Interpolation} (\begin{DoxyParamCaption}\item[{const size\+\_\+t}]{in\+Row\+Size, }\item[{const size\+\_\+t}]{in\+Col\+Size, }\item[{const size\+\_\+t}]{out\+Row\+Size, }\item[{const size\+\_\+t}]{out\+Col\+Size, }\item[{const size\+\_\+t}]{depth }\end{DoxyParamCaption})} The constructor for the Bilinear Interpolation. \begin{DoxyParams}{Parameters} {\em in\+Row\+Size} & Number of input rows. \\ \hline {\em in\+Col\+Size} & Number of input columns. \\ \hline {\em out\+Row\+Size} & Number of output rows. \\ \hline {\em out\+Col\+Size} & Number of output columns. \\ \hline {\em depth} & Number of input slices. \\ \hline \end{DoxyParams} \subsection{Member Function Documentation} \mbox{\label{classmlpack_1_1ann_1_1BilinearInterpolation_a633ef28f24c29c3438a9205786e817a3}} \index{mlpack\+::ann\+::\+Bilinear\+Interpolation@{mlpack\+::ann\+::\+Bilinear\+Interpolation}!Backward@{Backward}} \index{Backward@{Backward}!mlpack\+::ann\+::\+Bilinear\+Interpolation@{mlpack\+::ann\+::\+Bilinear\+Interpolation}} \subsubsection{Backward()} {\footnotesize\ttfamily void Backward (\begin{DoxyParamCaption}\item[{const arma\+::\+Mat$<$ eT $>$ \&}]{, }\item[{const arma\+::\+Mat$<$ eT $>$ \&}]{gradient, }\item[{arma\+::\+Mat$<$ eT $>$ \&}]{output }\end{DoxyParamCaption})} Ordinary feed backward pass of a neural network, calculating the function f(x) by propagating x backwards through f.
