Eigenstate Thermalization and Disorder Averaging in Gravity. [PDF]
Physical Review Letters, 2020 Naively, resolving the black hole information paradox requires microscopic details about quantum gravity. Recent work suggests that, instead, a unitary Page curve can be recovered by adding disorder-averaged replica instantons to the path integral ...

CoRR, 2013 Recent developments in Carrillo et al. (2012) and Carrillo et al. (2013) introduced a novel regularization method for compressive imaging in the context of compressed sensing with coherent redundant dictionaries. The approach relies on the observation that natural images exhibit strong average sparsity over multiple coherent frames.

Nonlinearities in Cross-Country Growth Regressions: A Bayesian Averaging of Thresholds (BAT) Approach [PDF]
, 2007 We propose a Bayesian Averaging of Thresholds (BAT) approach for assessing the existence and quantifying the effect of threshold effects in cross-country growth regressions in the presence of model uncertainty.

FFORMA: Feature-based forecast model averaging
International Journal of Forecasting, 2020 We propose an automated method for obtaining weighted forecast combinations using time series features. The proposed approach involves two phases. First, we use a collection of time series to train a meta-model for assigning weights to various possible ...

Randomized Kaczmarz with averaging [PDF]
BIT Numerical Mathematics, 2020 The randomized Kaczmarz (RK) method is an iterative method for approximating the least-squares solution of large linear systems of equations. The standard RK method uses sequential updates, making parallel computation difficult. Here, we study a parallel

Repeated judgment sampling: Boundaries
Judgment and Decision Making, 2011 This paper investigates the boundaries of the recent result that eliciting more than one estimate from the same person and averaging these can lead to accuracy gains in judgment tasks.

On non-conservative perturbations of three-dimensional integrable systems [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамикаAt present, non-conservative perturbations of two-dimensional nonlinear Hamiltonian systems have been studied quite fully. The purpose of the study is to generalize this theory to the three-dimensional case, when the unperturbed system is nonlinear ...

Mathematical Modelling and Analysis, 2008 A method of averaging along characteristics of weakly nonlinear hyperbolic systems, which was presented in earlier works of the author for one dimensional waves, is generalized for some cases of multidimensional wave problems.

Extracting Summary Statistics of Rapid Numerical Sequences
Frontiers in Psychology, 2021 We examine the ability of observers to extract summary statistics (such as the mean and the relative-variance) from rapid numerical sequences of two digit numbers presented at a rate of 4/s.

Mean Flow from Phase Averages in the 2D Boussinesq Equations
Atmosphere, 2023 The atmosphere and ocean are described by highly oscillatory PDEs that challenge both our understanding of their dynamics and their numerical approximation.
