WebExperiments with MNIST dataset. The plots below illustrate the training process of ResNet50 with Batch Normalization (left) and Fixup Initialization (right). Despite the training with Batch Normalizaion is more stable, training with Fixup Initialization coverages faster and yields better accuracy. WebHowever, fixup initializtion is able to solve this problem and even improve the convergence of the algorithm. Experiments with MNIST dataset The plots below illustrate the training process of ResNet50 with Batch Normalization (left) and Fixup Initialization (right). Webinitialization strategies for weight normalization and it is a common practice to use initialization schemes designed for un-normalized networks as a proxy. We study initialization conditions for weight normalized ReLU networks, and propose a new initialization strategy for both plain and residual architectures.
