Qualitative robustness for bootstrap approximations | An important property of statistical estimators is qualitative robustness,
that is small changes in the distribution of the data only result in small
chances of the distribution of the estimator. Moreover, in practice, the
distribution of the data is commonly unknown, therefore bootstrap
approximations can be used to... | 0 | 0 | 1 | 1 | 0 | 0 |
On Asymptotic Properties of Hyperparameter Estimators for Kernel-based Regularization Methods | The kernel-based regularization method has two core issues: kernel design and
hyperparameter estimation. In this paper, we focus on the second issue and
study the properties of several hyperparameter estimators including the
empirical Bayes (EB) estimator, two Stein's unbiased risk estimators (SURE) and
their corresp... | 1 | 0 | 0 | 0 | 0 | 0 |
SECS: Efficient Deep Stream Processing via Class Skew Dichotomy | Despite that accelerating convolutional neural network (CNN) receives an
increasing research focus, the save on resource consumption always comes with a
decrease in accuracy. To both increase accuracy and decrease resource
consumption, we explore an environment information, called class skew, which is
easily availabl... | 1 | 0 | 0 | 0 | 0 | 0 |
Implementation of infinite-range exterior complex scaling to the time-dependent complete-active-space self-consistent-field method | We present a numerical implementation of the infinite-range exterior complex

A consistent measure of the merger histories of massive galaxies using close-pair statistics I: Major mergers at $z < 3.5$ | We use a large sample of $\sim 350,000$ galaxies constructed by combining the
UKIDSS UDS, VIDEO/CFHT-LS, UltraVISTA/COSMOS and GAMA survey regions to probe
the major merging histories of massive galaxies ($>10^{10}\ \mathrm{M}_\odot$)

EE-Grad: Exploration and Exploitation for Cost-Efficient Mini-Batch SGD | We present a generic framework for trading off fidelity and cost in computing

Test of special relativity using a fiber network of optical clocks | Phase compensated optical fiber links enable high accuracy atomic clocks

Magnetic phases of spin-1 lattice gases with random interactions | A spin-1 atomic gas in an optical lattice, in the unit-filling Mott Insulator
(MI) phase and in the presence of disordered spin-dependent interaction, is

Is the kinetic equation for turbulent gas-particle flows ill-posed? | This paper is about well-posedness and realizability of the kinetic equation
for gas-particle flows and its relationship to the Generalized Langevin Model
(GLM) PDF equation. Previous analyses claim that this kinetic equation is
ill-posed, that in particular it has the properties of a backward heat equation

On the construction of small subsets containing special elements in a finite field | In this note we construct a series of small subsets containing a non-d-th
power element in a finite field by applying certain bounds on incomplete
character sums.
Precisely, let $h=\lfloor q^{\delta}\rfloor>1$ and $d\mid q^h-1$. Let $r$ be

Information Potential Auto-Encoders | In this paper, we suggest a framework to make use of mutual information as a
regularization criterion to train Auto-Encoders (AEs). In the proposed
framework, AEs are regularized by minimization of the mutual information

Irreducible compositions of degree two polynomials over finite fields have regular structure | Let $q$ be an odd prime power and $D$ be the set of monic irreducible
polynomials in $\mathbb F_q[x]$ which can be written as a composition of monic

accepted language. ... | 1 | 0 | 1 | 0 | 0 | 0 |
Quantum interferometry in multi-mode systems | We consider the situation when the signal propagating through each arm of an

Glider representations of chains of semisimple Lie algebras | We start the study of glider representations in the setting of semisimple Lie

Network Capacity Bound for Personalized PageRank in Multimodal Networks | In a former paper the concept of Bipartite PageRank was introduced and a
