Cnn affine
WebThe mean and standard-deviation are calculated per-dimension over the mini-batches and γ \gamma γ and β \beta β are learnable parameter vectors of size C (where C is the number of features or channels of the input). By default, the elements of γ \gamma γ are set to 1 and the elements of β \beta β are set to 0. The standard-deviation is calculated via the biased … WebAug 9, 2016 · Watch, create, and react to the best in live.
