emerging families for generative model learning, have largely been considered
as two distinct paradigms and received extensive independent studies
respectively. This ... | 1 | 0 | 0 | 1 | 0 | 0 |
DeepVisage: Making face recognition simple yet with powerful generalization skills | Face recognition (FR) methods report significant performance by adopting the
convolutional neural network (CNN) based learning methods. Although CNNs are
mostly trained by optimizing the softmax loss, the recent trend shows an
improvement of accuracy with different strategies, such as task-specific CNN
learning with ... | 1 | 0 | 0 | 0 | 0 | 0 |
The Erdős-Ginzburg-Ziv constant and progression-free subsets | Ellenberg and Gijswijt gave recently a new exponential upper bound for the
size of three-term arithmetic progression free sets in $({\mathbb Z_p})^n$,
where $p$ is a prime. Petrov summarized their method and generalized their
result to linear forms.
In this short note we use Petrov's result to give new exponential up... | 0 | 0 | 1 | 0 | 0 | 0 |
The Differing Relationships Between Size, Mass, Metallicity and Core Velocity Dispersion of Central and Satellite Galaxies | We study the role of environment in the evolution of central and satellite
galaxies with the Sloan Digital Sky Survey. We begin by studying the size-mass
relation, replicating previous studies, which showed no difference between the
sizes of centrals and satellites at fixed stellar mass, before turning our
attention ... | 0 | 1 | 0 | 0 | 0 | 0 |
Configuration Space Singularities of The Delta Manipulator | We investigate the configuration space of the Delta-Manipulator, identify 24
points in the configuration space, where the Jacobian of the Constraint
Equations looses rank and show, that these are not manifold points of the Real
Algebraic Set, which is defined by the Constraint Equations.

Constrained Optimisation of Rational Functions for Accelerating Subspace Iteration | Earlier this decade, the so-called FEAST algorithm was released for computing
the eigenvalues of a matrix in a given interval. Previously, rational filter
functions have been examined as a parameter of FEAST. In this thesis, we expand
on existing work with the following contributions: (i) Obtaining
well-performing ra... | 1 | 0 | 0 | 0 | 0 | 0 |
Sets of lengths in atomic unit-cancellative finitely presented monoids | For an element $a$ of a monoid $H$, its set of lengths $\mathsf L (a) \subset
\mathbb N$ is the set of all positive integers $k$ for which there is a
factorization $a=u_1 \cdot \ldots \cdot u_k$ into $k$ atoms. We study the
system $\mathcal L (H) = \{\mathsf L (a) \mid a \in H \}$ with a focus on the
unions $\mathcal... | 0 | 0 | 1 | 0 | 0 | 0 |
Spin-orbit effective fields in Pt/GdFeCo bilayers | In the increasing interests on spin-orbit torque (SOT) with various magnetic
materials, we investigated SOT in rare earth-transition metal ferrimagnetic
alloys. The harmonic Hall measurements were performed in Pt/GdFeCo bilayers to
quantify the effective fields resulting from the SOT. It is found that the

Bridging Static and Dynamic Program Analysis using Fuzzy Logic | Static program analysis is used to summarize properties over all dynamic
executions. In a unifying approach based on 3-valued logic properties are
either assigned a definite value or unknown. But in summarizing a set of
executions, a property is more accurately represented as being biased towards
true, or towards fal... | 1 | 0 | 0 | 0 | 0 | 0 |
The Formation of Heliospheric Arcs of Slow Solar Wind | A major challenge in solar and heliospheric physics is understanding how
highly localized regions, far smaller than 1 degree at the Sun, are the source
of solar-wind structures spanning more than 20 degrees near Earth. The Sun's
atmosphere is divided into magnetically open regions, coronal holes, where

A Construction of Infinitely Many Solutions to the Strominger System | In this paper we construct explicit smooth solutions to the Strominger system
on generalized Calabi-Gray manifolds, which are compact non-Kähler Calabi-Yau
3-folds with infinitely many distinct topological types and sets of Hodge
numbers.

A clustering algorithm for multivariate data streams with correlated components | Common clustering algorithms require multiple scans of all the data to
achieve convergence, and this is prohibitive when large databases, with data
arriving in streams, must be processed. Some algorithms to extend the popular
K-means method to the analysis of streaming data are present in literature
since 1998 (Bradl... | 0 | 0 | 1 | 1 | 0 | 0 |
Semantic Interpolation in Implicit Models | In implicit models, one often interpolates between sampled points in latent
space. As we show in this paper, care needs to be taken to match-up the
distributional assumptions on code vectors with the geometry of the
interpolating paths. Otherwise, typical assumptions about the quality and
semantics of in-between poin... | 1 | 0 | 0 | 1 | 0 | 0 |
Error analysis for global minima of semilinear optimal control problems | In [1] we consider an optimal control problem subject to a semilinear
elliptic PDE together with its variational discretization, where we provide a
condition which allows to decide whether a solution of the necessary first
order conditions is a global minimum. This condition can be explicitly
evaluated at the discret... | 0 | 0 | 1 | 0 | 0 | 0 |
Random dynamics of two-dimensional stochastic second grade fluids | In this paper, we consider a stochastic model of incompressible non-Newtonian
fluids of second grade on a bounded domain of $\mathbb{R}^2$ with
multiplicative noise. We first show that the solutions to the stochastic
equations of second grade fluids generate a continuous random dynamical system.
Second, we investigat... | 0 | 0 | 1 | 0 | 0 | 0 |

Hyperfunctions, the Duistermaat-Heckman theorem, and Loop Groups | In this article we investigate the Duistermaat-Heckman theorem using the

differential operators whi... | 0 | 0 | 1 | 0 | 0 | 0 |
When is selfish routing bad? The price of anarchy in light and heavy traffic | This paper examines the behavior of the price of anarchy as a function of the
traffic inflow in nonatomic congestion games with multiple origin-destination
(O/D) pairs. Empirical studies in real-world networks show that the price of
anarchy is close to 1 in both light and heavy traffic, thus raising the

Parallel Implementation of Lossy Data Compression for Temporal Data Sets | Many scientific data sets contain temporal dimensions. These are the data
storing information at the same spatial location but different time stamps.

them to s... | 1 | 0 | 0 | 0 | 0 | 0 |
