Lipschitz Constrained Parameter Initialization for Deep Transformers [PDF]

open access: yesProceedings of the 58th Annual Meeting of the Association for Computational Linguistics, 2020
The Transformer translation model employs residual connection and layer normalization to ease the optimization difficulties caused by its multi-layer encoder/decoder structure. Previous research shows that even with residual connection and layer normalization, deep Transformers still have difficulty in training, and particularly Transformer models with
