Cosh
Cosh // Elementwise hyperbolic cosine operation
Description
Produces a tensor of the same element type and shape as arg,
where
the value at each coordinate of output
is the hyperbolic cosine of
the value at the corresponding coordinate of arg.

Mathematical Definition
\mathtt{output}_{i_0, \ldots, i_{n-1}} = \cosh(\mathtt{arg}_{i_0, \ldots, i_{n-1}})
Backprop
\overline{\mathtt{arg}} \leftarrow \Delta\ \sinh(\mathtt{arg})
