Adaptive Importance Tempering: A flexible approach to improve computational efficiency of Metropolis Coupled Markov Chain Monte Carlo algorithms on binary spaces
Alexander Valencia-Sanchez, Jeffrey S. Rosenthal, Yasuhiro Watanabe +2
Based on the algorithm Informed Importance Tempering (IIT) proposed by Li et al. (2023) we propose an algorithm that uses an adaptive bounded balancing function. We argue why imple…

Exploring the generalizability of the optimal 0.234 acceptance rate in random-walk Metropolis and parallel tempering algorithms
Aidan Li, Liyan Wang, Tianye Dou +1
For random-walk Metropolis (RWM) and parallel tempering (PT) algorithms, an asymptotic acceptance rate of around 0.234 is known to be optimal in certain high-dimensional limits. Ho…

Quantifying the Speed-Up from Non-Reversibility in MCMC Tempering Algorithms
Gareth O. Roberts, Jeffrey S. Rosenthal
We investigate the increase in efficiency of simulated and parallel tempering MCMC algorithms when using non-reversible updates to give them "momentum". By making a connection to a…
