Researchers have introduced OneFlowSBI, a novel framework for simulation-based inference (SBI) that utilizes masked flow matching. This approach trains a single network to handle multiple types of queries, such as conditionals and marginals, by using a ternary mask to denote observed, generated, or absent data points. OneFlowSBI demonstrates improved performance on high-dimensional tasks like image denoising and shallow water inference, outperforming existing methods in posterior error and sampling speed while also providing likelihood and marginals without retraining.
