Sum

Description

The function that returns \mathsf{Sum} neural networks.

These are neural networks defined as such

\mathsf{Aff}_{\left[ \mathbb{I}_k \: \mathbb{I}_k \: \cdots \: \mathbb{I}_k\right],0_{k}}

Usage

Sum(n, k)

Arguments

n	number of copies of a certain vector to be summed.
k	the size of the summation vector.

Value

An affine neural network that will take a vector of size n \times k and return the summation vector that is of length k. See also Aff and Cpy.
