The \doxyref{Highway}{p.}{classmlpack_1_1ann_1_1Highway} class can vary its behavior between that of feed-\/forward fully connected network container and that of a layer which simply passes its inputs through depending on the transform gate. Note that the size of the input and output matrices of this class should be equal.
