See https://pytorch.org/docs/master/nn.functional.html#torch.nn.functional.instance_norm about the exact behavior of this functional. See the documentation for torch::nn::functional::InstanceNormFuncOptions class to learn what optional arguments are supported for this functional. Example: namespace F = torch::nn::functional; F::instance_norm(input, F::InstanceNormFuncOptions().running_mean(mean).running_var(variance).weight(weight).bias(bias).momentum( 0.1).eps(1e-5));

InstanceNorm1d. Applies Instance Normalization over a 3D input (a mini-batch of 1D inputs with optional additional channel dimension) as described in the paper Instance Normalization: The Missing Ingredient for Fast Stylization. The mean and standard-deviation are calculated per-dimension separately for each object in a mini-batch. \beta β are ...

InstanceNorm3d is applied on each channel of channeled data like 3D models with RGB color, but LayerNorm is usually applied on entire sample and often in NLP tasks. Additionally, LayerNorm applies elementwise affine transform, while InstanceNorm3d usually don’t apply affine transform. Parameters num_features – C C from an expected input of size

torch.norm(input, p='fro', dim=None, keepdim=False, out=None, dtype=None) [source] Returns the matrix norm or vector norm of a given tensor. Warning. torch.norm is deprecated and may be removed in a future PyTorch release. Its documentation and behavior may be incorrect, and it is no longer actively maintained.
