A generalization of a theorem of Hurewicz for quasi-Polish spaces | We identify four countable topological spaces $S_2$, $S_1$, $S_D$, and $S_0$
which serve as canonical examples of topological spaces which fail to be
quasi-Polish. These four spaces respectively correspond to the $T_2$, $T_1$,
$T_D$, and $T_0$-separation axioms. $S_2$ is the space of rationals, $S_1$ is

Reconstruction of stochastic 3-D signals with symmetric statistics from 2-D projection images motivated by cryo-electron microscopy | Cryo-electron microscopy provides 2-D projection images of the 3-D electron
scattering intensity of many instances of the particle under study (e.g., a
virus). Both symmetry (rotational point groups) and heterogeneity are important
aspects of biological particles and both aspects can be combined by describing

Gradient estimates for singular quasilinear elliptic equations with measure data | In this paper, we prove $L^q$-estimates for gradients of solutions to
singular quasilinear elliptic equations with measure data
$$-\operatorname{div}(A(x,\nabla u))=\mu,$$ in a bounded domain
$\Omega\subset\mathbb{R}^{N}$, where $A(x,\nabla u)\nabla u \asymp |\nabla

Learning Feature Nonlinearities with Non-Convex Regularized Binned Regression | For various applications, the relations between the dependent and independent
variables are highly nonlinear. Consequently, for large scale complex problems,
neural networks and regression trees are commonly preferred over linear models
such as Lasso. This work proposes learning the feature nonlinearities by
binning ... | 1 | 0 | 1 | 1 | 0 | 0 |
Empirical distributions of the robustified $t$-test statistics | Based on the median and the median absolute deviation estimators, and the
Hodges-Lehmann and Shamos estimators, robustified analogues of the conventional
$t$-test statistic are proposed. The asymptotic distributions of these
statistics are recently provided. However, when the sample size is small, it is

Exponential error rates of SDP for block models: Beyond Grothendieck's inequality | In this paper we consider the cluster estimation problem under the Stochastic
Block Model. We show that the semidefinite programming (SDP) formulation for
this problem achieves an error rate that decays exponentially in the
signal-to-noise ratio. The error bound implies weak recovery in the sparse
graph regime with b... | 1 | 0 | 1 | 1 | 0 | 0 |
Large-Margin Classification in Hyperbolic Space | Representing data in hyperbolic space can effectively capture latent

The airglow layer emission altitude cannot be determined unambiguously from temperature comparison with lidars | I investigate the nightly mean emission height and width of the OH*(3-1)
layer by comparing nightly mean temperatures measured by the ground-based

coincident measurements between November 2010 and February 2014, when GRIPS 9

Microscopic origin of the mobility enhancement at a spinel/perovskite oxide heterointerface revealed by photoemission spectroscopy | The spinel/perovskite heterointerface $\gamma$-Al$_2$O$_3$/SrTiO$_3$ hosts a
two-dimensional electron system (2DES) with electron mobilities exceeding those
in its all-perovskite counterpart LaAlO$_3$/SrTiO$_3$ by more than an order of

Ordered Monoids: Languages and Relations | We give a finite axiomatization for the variety generated by relational,

On the secrecy gain of $\ell$-modular lattices | We show that for every $\ell>1$, there is a counterexample to the
$\ell$-modular secrecy function conjecture by Oggier, Solé and Belfiore.
These counterexamples all satisfy the modified conjecture by Ernvall-Hytönen
and Sethuraman. Furthermore, we provide a method to prove or disprove the

Extremal invariant polynomials not satisfying the Riemann hypothesis | Zeta functions for linear codes were defined by Iwan Duursma in 1999. They
were generalized to the case of some invariant polynomials by the preset
author. One of the most important problems is whether extremal weight
enumerators satisfy the Riemann hypothesis. In this article, we show there

Fourier analysis of serial dependence measures | Classical spectral analysis is based on the discrete Fourier transform of the

HVACKer: Bridging the Air-Gap by Attacking the Air Conditioning System | Modern corporations physically separate their sensitive computational

attacker's main ch... | 1 | 0 | 0 | 0 | 0 | 0 |
Koszul binomial edge ideals of pairs of graphs | We study the Koszul property of a standard graded $K$-algebra $R$ defined by
the binomial edge ideal of a pair of graphs $(G_1,G_2)$. We show that the

$J_{G_1,G_2}$ of $R$ has a quadratic Gröbner basis; (iii) the graded maximal

On Loss Functions for Deep Neural Networks in Classification | Deep neural networks are currently among the most commonly used classifiers.
Despite easily achieving very good performance, one of the best selling points

Self-supervised learning of visual features through embedding images into text topic spaces | End-to-end training from scratch of current deep architectures for new

advantage of freely available multi-modal content to train computer vision
algorithms without h... | 1 | 0 | 0 | 0 | 0 | 0 |
Detector sampling of optical/IR spectra: how many pixels per FWHM? | Most optical and IR spectra are now acquired using detectors with

Accurate Single Stage Detector Using Recurrent Rolling Convolution | Most of the recent successful methods in accurate object detection and
