Structured Bayesian Gaussian process latent variable model: applications to data-driven dimensionality reduction and high-dimensional inversion
Steven Atkinson, Nicholas Zabaras
We introduce a methodology for nonlinear inverse problems using a variational Bayesian approach where the unknown quantity is a spatial field. A structured Bayesian Gaussian proces…
Structured Bayesian Gaussian process latent variable model
Steven Atkinson, Nicholas Zabaras
We introduce a Bayesian Gaussian process latent variable model that explicitly captures spatial correlations in data using a parameterized spatial kernel and leveraging structure-e…
Static Structural Signatures of Nearly Jammed Disordered and Ordered Hard-Sphere Packings: Direct Correlation Function
Steven Atkinson, Frank H. Stillinger, Salvatore Torquato
Dynamical signatures are known to precede jamming in hard-particle systems, but static structural signatures have proven more elusive. The observation that compressing hard-particl…
Critical slowing down and hyperuniformity on approach to jamming
Steven Atkinson, Ge Zhang, Adam B. Hopkins +1
Hyperuniformity characterizes a state of matter that is poised at a critical point at which density or volume-fraction fluctuations are anomalously suppressed at infinite wavelengt…
Maximally dense packings of two-dimensional convex and concave noncircular particles
Steven Atkinson, Yang Jiao, Salvatore Torquato
Dense packings of hard particles have important applications in many fields, including condensed matter physics, discrete geometry and cell biology. In this paper, we employ a stoc…
