Catastrophic Collapse of the Atlantic Overturning Circulation: Is it near a tipping point?
The Atlantic Meridional Overturning Circulation (AMOC) plays a crucial role in the climate of the Northern Hemisphere. By transporting warm water north, it keeps Western Europe and Eastern US and Canada warm. It is commonly thought that if AMOC slows or collapses, Northern Hemisphere would enter an ice age, as it apparently happened in the distant past. […]
A simple recipe for CREPE: Controlling REPlica-Exchange via neural transports
Markov Chain Monte Carlo (MCMC) is a powerful algorithmic framework for sampling from complex probability distributions. Standard MCMC methods struggle with high-dimensional distributions containing well-separated modes, becoming trapped in local regions. Replica-exchange/Parallel tempering (PT) addresses this by using intermediate annealing distributions to bridge a tractable reference (e.g., Gaussian) and an intractable target distribution. However, classical […]
