extents, and peripheral nodes are sparsely interconnected. Core-periphery
structure composed of a single core and periphery has been identified for
various networks. However, a... | 1 | 1 | 0 | 0 | 0 | 0 |
Central Limit Theorems of Local Polynomial Threshold Estimators for Diffusion Processes with Jumps | Central limit theorems play an important role in the study of statistical
inference for stochastic processes. However, when the nonparametric local
polynomial threshold estimator, especially local linear case, is employed to
estimate the diffusion coefficients of diffusion processes, the adaptive and
predictable stru... | 0 | 0 | 1 | 0 | 0 | 0 |
Honey from the Hives: A Theoretical and Computational Exploration of Combinatorial Hives | In the first half of this manuscript, we begin with a brief review of
combinatorial hives as introduced by Knutson and Tao, and focus on a conjecture
by Danilov and Koshevoy for generating such a hive from Hermitian matrix pairs
through an optimization scheme. We examine a proposal by Appleby and Whitehead
in the spi... | 0 | 0 | 0 | 1 | 0 | 0 |
Pressure-induced ferromagnetism due to an anisotropic electronic topological transition in Fe1.08Te | A rapid and anisotropic modification of the Fermi-surface shape can be
associated with abrupt changes in crystalline lattice geometry or in the
magnetic state of a material. In this study we show that such an electronic
topological transition is at the basis of the formation of an unusual
pressure-induced tetragonal ... | 0 | 1 | 0 | 0 | 0 | 0 |
DataSlicer: Task-Based Data Selection for Visual Data Exploration | In visual exploration and analysis of data, determining how to select and
transform the data for visualization is a challenge for data-unfamiliar or
inexperienced users. Our main hypothesis is that for many data sets and common
analysis tasks, there are relatively few "data slices" that result in effective
visualizat... | 1 | 0 | 0 | 0 | 0 | 0 |
Convolutional Analysis Operator Learning: Acceleration, Convergence, Application, and Neural Networks | Convolutional operator learning is increasingly gaining attention in many
signal processing and computer vision applications. Learning kernels has mostly
relied on so-called local approaches that extract and store many overlapping

Several Classes of Permutation Trinomials over $\mathbb F_{5^n}$ From Niho Exponents | The construction of permutation trinomials over finite fields attracts
people's interest recently due to their simple form and some additional

that permute the set o... | 1 | 0 | 0 | 0 | 0 | 0 |
Core-powered mass loss and the radius distribution of small exoplanets | Recent observations identify a valley in the radius distribution of small
exoplanets, with planets in the range $1.5-2.0\,{\rm R}_{\oplus}$ significantly
less common than somewhat smaller or larger planets. This valley may suggest a
bimodal population of rocky planets that are either engulfed by massive gas

Comparison of Gini index and Tamura coefficient for holographic autofocusing based on the edge sparsity of the complex optical wavefront | The Sparsity of the Gradient (SoG) is a robust autofocusing criterion for
holography, where the gradient modulus of the complex refocused hologram is
calculated, on which a sparsity metric is applied. Here, we compare two
different choices of sparsity metrics used in SoG, specifically, the Gini index
(GI) and the Tam... | 0 | 1 | 0 | 0 | 0 | 0 |
Probabilistic interpretation of HJB equations by the representation theorem for generators of BSDEs | The purpose of this note is to propose a new approach for the probabilistic

A Review on Deep Learning Techniques Applied to Semantic Segmentation | Image semantic segmentation is more and more being of interest for computer

demand coinci... | 1 | 0 | 0 | 0 | 0 | 0 |
Sum-Product Networks for Hybrid Domains | While all kinds of mixed data -from personal data, over panel and scientific
data, to public and commercial data- are collected and stored, building
probabilistic graphical models for these hybrid domains becomes more difficult.
Users spend significant amounts of time in identifying the parametric form of
the random ... | 1 | 0 | 0 | 1 | 0 | 0 |
Unified Hypersphere Embedding for Speaker Recognition | Incremental improvements in accuracy of Convolutional Neural Networks are
usually achieved through use of deeper and more complex models trained on

seek to improve the i... | 1 | 0 | 0 | 0 | 0 | 0 |
Linearly-Recurrent Autoencoder Networks for Learning Dynamics | This paper describes a method for learning low-dimensional approximations of

Macros to Conduct Tests of Multimodality in SAS | The Dip Test of Unimodality and Silverman's Critical Bandwidth Test are two

The James construction and $π_4(\mathbb{S}^3)$ in homotopy type theory | In the first part of this paper we present a formalization in Agda of the

Graph-Based Ascent Algorithms for Function Maximization | We study the problem of finding the maximum of a function defined on the
nodes of a connected graph. The goal is to identify a node where the function
obtains its maximum. We focus on local iterative algorithms, which traverse the

neighbors of t... | 1 | 0 | 0 | 1 | 0 | 0 |
Multiequilibria analysis for a class of collective decision-making networked systems | The models of collective decision-making considered in this paper are

Isotopes of Octonion Algebras, G2-Torsors and Triality | Octonion algebras over rings are, in contrast to those over fields, not
determined by their norm forms. Octonion algebras whose norm is isometric to
the norm q of a given algebra C are twisted forms of C by means of the
Aut(C)-torsor O(q) ->O(q)/Aut(C). We show that, over any commutative unital
ring, these twisted fo... | 0 | 0 | 1 | 0 | 0 | 0 |
