The Diffusion-Attention Connection

Transformers, diffusion-maps, and magnetic Laplacians are usually treated as separate tools; we show they are all different regimes of a single Markov geometry built from pre-softmax query-scores. We define a QK “bidivergence” whose exponentiated and normalized forms yield attention, diffusion-maps, and magnetic diffusion. And use product of experts and Schrödinger-bridges to connect and organize them into equilibrium, nonequilibrium steady-state, and driven dynamics.
