Bi-Anchor Interpolation Solver for Accelerating Generative Modeling

The Bi-Anchor Interpolation Solver (BA-solver) has been introduced to enhance the efficiency of Flow Matching models by addressing the latency issues associated with iterative ODE solving. By incorporating a lightweight SideNet that approximates future and historical velocities, BA-solver achieves high-quality generation comparable to a 100+ Neural Function Evaluations (NFEs) Euler solver using only 10 NFEs, while allowing for minimal training costs and seamless integration into existing generative models. This advancement is significant for practitioners as it enables faster and more versatile generative modeling without sacrificing output fidelity, facilitating applications like image editing.
