Web16 aug. 2024 · Pytorch’s nn.layernorm layer is a normalization layer for neural networks. It is used to normalize the input data to have zero mean and unit variance. The layer is commonly used in Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs). The layer has been shown to improve the accuracy of both CNNs and RNNs.
