Researchers have developed a mean-field theory to analyze multi-head self-attention models trained with cross-entropy. The study treats each attention head as a particle, using the empirical law of heads as a state variable in an infinite-head limit. This framework establishes a nonlinear Wasserstein gradient-flow equation and provides theoretical bounds and convergence rates for training dynamics, offering a rigorous baseline for understanding attention mechanisms.
