Transformers are ubiquitous. They influence nearly every aspect of modern AI. However, the mechanics of their training remain poorly understood. This poses a problem for the field due to the immense amounts of data, computational power, and energy being invested in the training of these networks. I highlight a recent intriguing empirical result from our group. Specifically, although self-attention catastrophically fails to train without a skip connection under standard conditions, deep transformers can in fact be trained successfully without them. In this talk, I explore what makes this possible and what it reveals about the fundamental training dynamics of modern transformers. I also speculate on why truly deep networks may be important for improving generalization and efficiency.
