Researchers have developed a new method called Langevin simulated bifurcation (LSB) for faster and more parallel sampling from Boltzmann distributions, which are fundamental in various applications. To address the challenge of estimating the effective temperature of samples generated by these fast samplers, they introduced conditional expectation matching (CEM). This estimation method is efficient for energy-based models with exploitable conditional independence structures. Combining these, a learning framework named sampler adaptive learning (SAL) was created to adaptively adjust model temperature to match that of the distribution induced by fast non-MCMC sampling, demonstrating effectiveness on semi-restricted Boltzmann machines.
