init

public MPSNNConcatenationNode init()

Overrides:

init in class MPSNNFilterNode

initWithSources

public MPSNNConcatenationNode initWithSources(NSArray<? extends MPSNNImageNode> sourceNodes)

Init a node that concatenates feature channels from multiple images

In some neural network designs, it is necessary to append feature channels from one neural network filter to the results of another. If we have three image nodes with M, N and O feature channels in them, passed to -initWithSources: as @[imageM, imageN, imageO], then feature channels [0,M-1] will be drawn from image M, feature channels [M, M+N-1] will be drawn from image N and feature channels [M+N, M+N+O-1] will be drawn from image O.

As all images are padded out to a multiple of four feature channels, M, N and O here are also multiples of four, even when the MPSImages are not. That is, if the image is 23 feature channels and one channel of padding, it takes up 24 feature channels worth of space in the concatenated result.

Performance Note: Generally, concatenation is free as long as all of the sourceNodes are produced by filters in the same MPSNNGraph. Most MPSCNNKernels have the ability to write their results at a feature channel offset within a target MPSImage. However, if the MPSNNImageNode source nodes come from images external to the MPSNNGraph, then we have to do a copy operation to assemble the concatenated node. As a result, when deciding where to break a large logical graph into multiple smaller MPSNNGraphs, it is better for concatenations to appear at the ends of subgraphs when possible rather than at the start, to the extent that all the images used in the concatenation are produced by that subgraph.

Parameters:

sourceNodes - The MPSNNImageNode representing the source MPSImages for the filter

Returns:

A new MPSNNFilter node that concatenates its inputs.

nodeWithSources

public static MPSNNConcatenationNode nodeWithSources(NSArray<? extends MPSNNImageNode> sourceNodes)

Init a autoreleased node that concatenates feature channels from multiple images

In some neural network designs, it is necessary to append feature channels from one neural network filter to the results of another. If we have three image nodes with M, N and O feature channels in them, passed to -initWithSources: as @[imageM, imageN, imageO], then feature channels [0,M-1] will be drawn from image M, feature channels [M, M+N-1] will be drawn from image N and feature channels [M+N, M+N+O-1] will be drawn from image O.

As all images are padded out to a multiple of four feature channels, M, N and O here are also multiples of four, even when the MPSImages are not. That is, if the image is 23 feature channels and one channel of padding, it takes up 24 feature channels worth of space in the concatenated result.

Parameters:

sourceNodes - The MPSNNImageNode representing the source MPSImages for the filter

A new MPSNNFilter node that concatenates its inputs.
