New theory explains Transformer generalization delay via Bayesian inference

Researchers have proposed a new theory explaining why Transformer models delay generalization after memorizing training data. The theory frames attention mechanisms as implicit Bayesian posteriors over task dependency graphs, suggesting that generalization requires both a suitable MLP capacity and a novel Bayesian structural condition. This condition mandates that attention must assign sufficient weight to all informative tokens, and its failure leads to delayed structural inference, which can be bypassed with specific interventions.
