Researchers have investigated geometric tempering as a method for sampling from probability distributions, framing it as an optimization problem. Their work analyzes the impact of using a sequence of moving targets on Wasserstein and Fisher-Rao gradient flows, establishing exponential convergence bounds. The study also examines time-discretized versions of these methods, finding that geometric mixtures of initial and target distributions do not accelerate convergence in the Fisher-Rao case. AI
