Memory effects, transient growth, and wave breakup in a model of paced atrium | The mechanisms underlying cardiac fibrillation have been investigated for

An Analysis of the Value of Information when Exploring Stochastic, Discrete Multi-Armed Bandits | In this paper, we propose an information-theoretic exploration strategy for

Functorial compactification of linear spaces | We define compactifications of vector spaces which are functorial with

Being Robust (in High Dimensions) Can Be Practical | Robust estimation is much more challenging in high dimensions than it is in
one dimension: Most techniques either lead to intractable optimization problems
or estimators that can tolerate only a tiny fraction of errors. Recent work in
theoretical computer science has shown that, in appropriate distributional
models, ... | 1 | 0 | 0 | 1 | 0 | 0 |
Properties of In-Plane Graphene/MoS2 Heterojunctions | The graphene/MoS2 heterojunction formed by joining the two components
laterally in a single plane promises to exhibit a low-resistance contact
according to the Schottky-Mott rule. Here we provide an atomic-scale
description of the structural, electronic, and magnetic properties of this type
of junction. We first iden... | 0 | 1 | 0 | 0 | 0 | 0 |
Semi-extraspecial groups with an abelian subgroup of maximal possible order | Let $p$ be a prime. A $p$-group $G$ is defined to be semi-extraspecial if for
every maximal subgroup $N$ in $Z(G)$ the quotient $G/N$ is a an extraspecial
group. In addition, we say that $G$ is ultraspecial if $G$ is semi-extraspecial
and $|G:G'| = |G'|^2$. In this paper, we prove that every $p$-group of

Genetic and Memetic Algorithm with Diversity Equilibrium based on Greedy Diversification | The lack of diversity in a genetic algorithm's population may lead to a bad
performance of the genetic operators since there is not an equilibrium between
exploration and exploitation. In those cases, genetic algorithms present a fast
and unsuitable convergence.
In this paper we develop a novel hybrid genetic algorit... | 1 | 0 | 0 | 0 | 0 | 0 |
Determinants of Mobile Money Adoption in Pakistan | In this work, we analyze the problem of adoption of mobile money in Pakistan

Cherlin's conjecture for almost simple groups of Lie rank 1 | We prove Cherlin's conjecture, concerning binary primitive permutation
groups, for those groups with socle isomorphic to $\mathrm{PSL}_2(q)$,
${^2\mathrm{B}_2}(q)$, ${^2\mathrm{G}_2}(q)$ or $\mathrm{PSU}_3(q)$. Our method
uses the notion of a "strongly non-binary action".

Universal Function Approximation by Deep Neural Nets with Bounded Width and ReLU Activations | This article concerns the expressive power of depth in neural nets with ReLU
activations and bounded width. We are particularly interested in the following
questions: what is the minimal width $w_{\text{min}}(d)$ so that ReLU nets of
width $w_{\text{min}}(d)$ (and arbitrary depth) can approximate any continuous

Network Essence: PageRank Completion and Centrality-Conforming Markov Chains | Jiří Matoušek (1963-2015) had many breakthrough contributions in

spaces or linear programs --- Jirka found the essence of the challenging

A Regularized Framework for Sparse and Structured Neural Attention | Modern neural networks are often augmented with an attention mechanism, which
tells the network where to focus within the input. We propose in this paper a
new framework for sparse and structured attention, building upon a smoothed max
operator. We show that the gradient of this operator defines a mapping from
real v... | 1 | 0 | 0 | 1 | 0 | 0 |
Intrinsically Motivated Goal Exploration Processes with Automatic Curriculum Learning | Intrinsically motivated spontaneous exploration is a key enabler of
autonomous lifelong learning in human children. It allows them to discover and

unsupervised multi-go... | 1 | 0 | 0 | 0 | 0 | 0 |
Sentiment Perception of Readers and Writers in Emoji use | Previous research has traditionally analyzed emoji sentiment from the point

On C-class equations | The concept of a C-class of differential equations goes back to E. Cartan

Confidence Intervals for Quantiles from Histograms and Other Grouped Data | Interval estimation of quantiles has been treated by many in the literature.
However, to the best of our knowledge there has been no consideration for

Reach and speed of judgment propagation in the laboratory | In recent years, a large body of research has demonstrated that judgments and
behaviors can propagate from person to person. Phenomena as diverse as

judgment propagation are... | 1 | 1 | 0 | 0 | 0 | 0 |
Texture Characterization by Using Shape Co-occurrence Patterns | Texture characterization is a key problem in image understanding and pattern

Exact solution of a two-species quantum dimer model for pseudogap metals | We present an exact ground state solution of a quantum dimer model introduced

hole-doped resonating valence bond liquid. Interestingly, this model captures

Strong instability of standing waves for nonlinear Schrödinger equations with a partial confinement | We study the instability of standing wave solutions for nonlinear
Schrödinger equations with a one-dimensional harmonic potential in
dimension $N\ge 2$. We prove that if the nonlinearity is $L^2$-critical or
supercritical in dimension $N-1$, then any ground states are strongly unstable
by blowup.

Multi-armed Bandit Problems with Strategic Arms | We study a strategic version of the multi-armed bandit problem, where each

an amount $x_a$ to pass on to the principal (keeping $v_a-x_a$ for itself). All
