Detailed Description
This depends on Metal.framework. Specifies the addition gradient operator. This arithmetic gradient filter requires the following inputs:
gradient image from the previous layer (going backwards) and either the primary or the secondary source image from the forward pass. You
will need a separate filter for the primary and secondary source images.
Without broadcasting, the arithmetic add gradient operation is a copy operation on the input gradient image. It is the same operation for
both the primary and secondary source images (for x + y, d/dx(x + y) = 1, d/dy(x + y) = 1). This copy operation can be optimized away by
the graph interface.
Setting the broadcasting parameters results in a reduction operation (sum) across all of the applicable broadcasting dimensions (rows,
columns, feature channels, or any combination thereof) to produce the destination image of the size that matches the primary/secondary
input images used in the forward pass.
