General
~~~~~~~
MaxPool operation performs the computation following the below formulas. Variable names follow the standard :ref:`Naming Conventions <doxid-dev_guide_conventions>`.
.. math::
\dst(n, c, oh, ow) = \max\limits_{kh, kw} \left( \src(n, c, oh \cdot SH + kh \cdot (DH + 1) - PH_L, ow \cdot SW + kw \cdot (DW + 1) - PW_L) \right)
