Analytic bridge diffusions offer controlled path generation without neural networks

Researchers have developed a new method called Analytic Bridge Diffusions (LQ-GM-PID) that can generate controlled paths without relying on neural networks for optimization. This approach analytically solves a restricted class of transport problems, providing closed-form solutions for score, intermediate marginals, and protocol gradients. The method is demonstrated to be efficient, achieving sub-50ms precomputation on a laptop for complex tasks, and serves as a benchmark for current neural bridge-diffusion techniques. AI
