WebChannel Shuffle is an operation to help information flow across feature channels in convolutional neural networks. It was used as part of the ShuffleNet architecture. If we allow a group convolution to obtain input data from different groups, the input and output channels will be fully related. Specifically, for the feature map generated from the previous … WebFeb 5, 2016 · The Shuffle is an expensive operation since it involves disk I/O, data serialization, and network I/O. And the why? During computations, a single task will operate on a single partition — thus, to organize all the data for a single reduceByKey reduce task to execute, Spark needs to perform an all-to-all operation.
