Nettet13. jan. 2024 · In this report, we will look into yet another widely used normalization technique in deep learning: group normalization. First introduced by Wu et.al.[1], group normalization serves as an alternative to layer normalization and Instance normalization for tackling the same statistical instabilities posed by batch normalization. NettetAn instance normalization layer normalizes a mini-batch of data across each channel for each observation independently. To improve the convergence of training the convolutional neural network and reduce the sensitivity to network hyperparameters, use instance normalization layers between convolutional layers and nonlinearities, such as ReLU … the hub grill and bar menu
