WebJan 15, 2024 · The original definition of the Ising model is silent on such matters, but the programmer must make a commitment one way or another. This is where Glauber dynamics enters the story. Glauber presented a … Webof Markovian dynamics from observed data governed by local interactions. Concretely, we suppose that such local interactions are represented by a graphical model. We observe a single-site dynamics, specifically the so-called Glauber dynamics, and wish to learn the graph underlying the model. This work fits within a broader theme of learning

In statistical physics, Glauber dynamics is a way to simulate the Ising model (a model of magnetism) on a computer. It is a type of Markov Chain Monte Carlo algorithm. See more Metropolis–Hastings algorithm gives identical results as Glauber algorithm does, but it is faster. In the Metropolis algorithm, selecting a spin is deterministic. Usually, one may select the spins one by one following some … See more • Metropolis algorithm • Ising model • Monte Carlo algorithm • Simulated annealing See more The algorithm is named after Roy J. Glauber. See more • Simulation package IsingLenzMC provides simulation of Glauber Dynamics on 1D lattices with external field. CRAN. See more WebMarkov chain known as the Glauber dynamics converges very quickly to its stationary distribution in the tree uniqueness region, i.e., decay of correlations region. The Glauber dynamics is the quintessential example of a local Markov chain, and its convergence rate is of great interest due to its simplicity and wide applicability. Webstudy Glauber dynamics for families of finite graphs of bounded degree. We show that if the inverse spectral gap of the Glauber dynamics on the ball centered at ρstays bounded as the ball grows, then the correlation between the state of a vertex ρand the states of vertices at distance rfrom ρ, must decay exponentially in r.
