Are Vortex Quasi-Crystals New Phases of Vortex Matter? [article]

Wei Zhang, C. A. R. Sa de Melo
2006 arXiv   pre-print
It is argued that vortex quasi-crystals are stabilized due to imposed quasi-periodic potentials in large samples or due to boundary and surface energy effects for samples of special shapes and sizes.  ...  For finite size samples, it is proposed that a phase transition between a vortex crystal and a vortex quasi-crystal occurs as a function of magnetic field and temperature as the sample size is reduced.  ...  The general subject of vortex physics in superconductors is quite interesting since there seems to be a large variety of possible equilibrium vortex phases in superconductors [1] .  ...

2022 arXiv   pre-print
They used a technique called Gibbs Sampling with People [GSP; 35, see Fig. 2 ] that samples internal prior distributions by putting humans "in the loop" of a Gibbs sampler.  ...  This network is then used to generate samples, using the exact same process as used to generate samples from human priors using Gibbs sampling.  ...  The hyperparameter sweep was done by sampling from the space of hyperparameter using the Tree-Structured Parzen Estimator [48] .  ...

A generalisation of the honeycomb dimer model to higher dimensions [article]

Piet Lammers
2019 arXiv   pre-print
Each sample of the model is both a tiling and a height function. First, we derive a surprising identity for the covariance structure of the model.  ...  results rely on the development of the boundary swap, which is a versatile technique for understanding the model; it is inspired by the double dimer model, works in any dimension, and may be of independent interest  ...  The measure µ is called a Gibbs measure if for every finite R ⊂ X d , the distribution of f in µ is the same as the distribution of a sample f obtained by first sampling g from µ, then sampling f from  ...

The informed sampler: A discriminative approach to Bayesian inference in generative computer vision models

Varun Jampani, Sebastian Nowozin, Matthew Loper, Peter V. Gehler
2015 Computer Vision and Image Understanding  
Since the tiles are independent except for occlusion we use a block-Gibbs like scheme in our sampler where we propose changes to one tile at a time.  ...  Metropolis Hastings within Gibbs (MHWG).  ...  The informed sampling approach (INF-BMHWG) is better than the best baseline (MHWG). This still is a very challenging problem since the parameters for occluded tiles are flat over a large region.  ...
