Accurate derivatives enable efficient gradient-based inference, and for the Point/Finite sub-degeneracy in KMT-2025-BLG-1314, HMC mixes more robustly than traditional MCMC.http://haibinren.com/works/microlux/Tue, 21 Jan 2025 00:00:00 +0000http://haibinren.com/works/microlux/We develop a differentiable binary microlensing model with adaptive contour integration. The code extends VBBinaryLensing and uses JAX to compute accurate light curves and derivatives for optimization and inference.
