Web5 jul. 2024 · Re your MobileVit2, these two norms are not equivalent and it would be misleading to call it LayerNorm2d as the group norm w/ groups=1 is not equivalent. 'LayerNorm2d' is already used elsewhere in other nets. Might be worth retraining MobileVit2 with an actual LayerNorm or renaming the norm to just GroupNorm.

LayerNorm有什么作用 - CSDN
Web均值和标准差是在最后 D 维度上计算的,其中 D 是 normalized_shape 的维度。 例如,如果 normalized_shape 是 (3, 5)(二维形状),则在输入的最后 2 维(即 input.mean((-2, -1)))上计算平均值和标准差。\gamma 和 \beta 是 normalized_shape 的可学习仿射变换参数,如果 elementwise_affine 是 True 。 标准差是通过有偏估计器计算的 ... Web21 jul. 2016 · Layer normalization is very effective at stabilizing the hidden state dynamics in recurrent networks.
