Large-Scale Cox Process Inference using Variational Fourier Features | Gaussian process modulated Poisson processes provide a flexible framework for
modelling spatiotemporal point patterns. So far this had been restricted to one
dimension, binning to a pre-determined grid, or small data sets of up to a few
thousand data points. Here we introduce Cox process inference based on Fourier

Buildings-to-Grid Integration Framework | This paper puts forth a mathematical framework for Buildings-to-Grid (BtG)
integration in smart cities. The framework explicitly couples power grid and

performance. Simplif... | 1 | 0 | 1 | 0 | 0 | 0 |
Oxygen Partial Pressure during Pulsed Laser Deposition: Deterministic Role on Thermodynamic Stability of Atomic Termination Sequence at SrRuO3/BaTiO3 Interface | With recent trends on miniaturizing oxide-based devices, the need for
atomic-scale control of surface/interface structures by pulsed laser deposition
(PLD) has increased. In particular, realizing uniform atomic termination at the
surface/interface is highly desirable. However, a lack of understanding on the

A Data-Driven Analysis of the Influence of Care Coordination on Trauma Outcome | OBJECTIVE: To test the hypothesis that variation in care coordination is

Construction of Non-asymptotic Confidence Sets in 2-Wasserstein Space | In this paper, we consider a probabilistic setting where the probability
measures are considered to be random objects. We propose a procedure of
construction non-asymptotic confidence sets for empirical barycenters in

non-parametric two-sample test... | 0 | 0 | 1 | 1 | 0 | 0 |
Limits on statistical anisotropy from BOSS DR12 galaxies using bipolar spherical harmonics | We measure statistically anisotropic signatures imprinted in
three-dimensional galaxy clustering using bipolar spherical harmonics (BipoSHs)

parametrized by $P(\vec... | 0 | 1 | 0 | 0 | 0 | 0 |
A Central Limit Theorem for Wasserstein type distances between two different laws | This article is dedicated to the estimation of Wasserstein distances and
Wasserstein costs between two distinct continuous distributions $F$ and $G$ on

Confidence Intervals for Stochastic Arithmetic | Quantifying errors and losses due to the use of Floating-Point (FP)

Contaminated speech training methods for robust DNN-HMM distant speech recognition | Despite the significant progress made in the last years, state-of-the-art

Co-segmentation for Space-Time Co-located Collections | We present a co-segmentation technique for space-time co-located image

resulting in ambiguities fo... | 1 | 0 | 0 | 0 | 0 | 0 |
Speaker Diarization with LSTM | For many years, i-vector based audio embedding techniques were the dominant

Use of Source Code Similarity Metrics in Software Defect Prediction | In recent years, defect prediction has received a great deal of attention in

Connecting pairwise spheres by depth: DCOPS | We extend the classical notion of the spherical depth in \mathbb{R}^k, to the

Estimating the spectral gap of a trace-class Markov operator | The utility of a Markov chain Monte Carlo algorithm is, in large part,

On Lie algebras responsible for zero-curvature representations of multicomponent (1+1)-dimensional evolution PDEs | Zero-curvature representations (ZCRs) are one of the main tools in the theory
of integrable $(1+1)$-dimensional PDEs. According to the preprint

Scalable Surface Reconstruction from Point Clouds with Extreme Scale and Density Diversity | In this paper we present a scalable approach for robustly computing a 3D

General Bounds for Incremental Maximization | We propose a theoretical framework to capture incremental solutions to

Arrangements of pseudocircles on surfaces | A pseudocircle is a simple closed curve on some surface. Arrangements of

which requires ... | 1 | 0 | 1 | 0 | 0 | 0 |
Scalable methods for Bayesian selective inference | Modeled along the truncated approach in Panigrahi (2016), selection-adjusted
