Estimating Orbital Parameters of Direct Imaging Exoplanet Using Neural Network
Warm-starting parallel-tempered MCMC with flow-matching posterior proposals infers β Pictoris b's orbit about 78-365× faster than conventional samplers with comparable posteriors, though the comparison is not fully apples-to-apples.
