A new paper formally proves that transformer architectures can function as complete Bayesian processes. The research, conducted within the measure-theoretic kernel framework, demonstrates that when transformers meet specific Bayes joint-distribution conditions, their internal computations are equivalent to exact Bayesian posterior inference. This equivalence holds from core Bayesian transformers to full multilayer stacks, with the softmax attention mechanism specifically shown to induce a valid probability distribution. AI
IMPACT This research provides a formal theoretical foundation for understanding transformer architectures as Bayesian inference engines, potentially guiding future model design and interpretability efforts.
