WebT-Fixup. T-Fixup is an initialization method for Transformers that aims to remove the need for layer normalization and warmup. The initialization procedure is as follows: Apply Xavier initialization for all parameters excluding input embeddings. Use Gaussian initialization N ( 0, d − 1 2) for input embeddings where d is the embedding dimension. WebHowever, fixup initializtion is able to solve this problem and even improve the convergence of the algorithm.
