Game-Theoretic Design of Secure and Resilient Distributed Support Vector Machines with Adversaries | With a large number of sensors and control units in networked systems,
distributed support vector machines (DSVMs) play a fundamental role in scalable
and efficient multi-sensor classification and prediction tasks. However, DSVMs
are vulnerable to adversaries who can modify and generate data to deceive the
system to ... | 1 | 0 | 0 | 1 | 0 | 0 |
Rank conditional coverage and confidence intervals in high dimensional problems | Confidence interval procedures used in low dimensional settings are often
inappropriate for high dimensional applications. When a large number of
parameters are estimated, marginal confidence intervals associated with the
most significant estimates have very low coverage rates: They are too small and
centered at bias... | 0 | 0 | 0 | 1 | 0 | 0 |
Phase-Encoded Hyperpolarized Nanodiamond for Magnetic Resonance Imaging | Surface-functionalized nanomaterials can act as theranostic agents that
detect disease and track biological processes using hyperpolarized magnetic
resonance imaging (MRI). Candidate materials are sparse however, requiring
spinful nuclei with long spin-lattice relaxation (T1) and spin-dephasing times
(T2), together w... | 0 | 1 | 0 | 0 | 0 | 0 |
k-Space Deep Learning for Reference-free EPI Ghost Correction | Nyquist ghost artifacts in EPI images are originated from phase mismatch
between the even and odd echoes. However, conventional correction methods using
reference scans often produce erroneous results especially in high-field MRI
due to the non-linear and time-varying local magnetic field changes. Recently,
it was sh... | 0 | 0 | 0 | 1 | 0 | 0 |
Binary Search in Graphs Revisited | In the classical binary search in a path the aim is to detect an unknown
target by asking as few queries as possible, where each query reveals the
direction to the target. This binary search algorithm has been recently
extended by [Emamjomeh-Zadeh et al., STOC, 2016] to the problem of detecting a
target in an arbitra... | 1 | 0 | 0 | 0 | 0 | 0 |
Dissecting Adam: The Sign, Magnitude and Variance of Stochastic Gradients | The ADAM optimizer is exceedingly popular in the deep learning community.
Often it works very well, sometimes it doesn't. Why? We interpret ADAM as a
combination of two aspects: for each weight, the update direction is determined
by the sign of stochastic gradients, whereas the update magnitude is determined
by an es... | 1 | 0 | 0 | 1 | 0 | 0 |
Econometric Modeling of Regional Electricity Spot Prices in the Australian Market | Wholesale electricity markets are increasingly integrated via high voltage
interconnectors, and inter-regional trade in electricity is growing. To model
this, we consider a spatial equilibrium model of price formation, where
constraints on inter-regional flows result in three distinct equilibria in
prices. We use thi... | 0 | 0 | 0 | 1 | 0 | 0 |
Accurate Effective Medium Theory for the Analysis of Spoof Localized Surface Plasmons in Textured Metallic Cylinders | It has been recently demonstrated that textured closed surfaces which are
made out of perfect electric conductors (PECs) can mimic highly localized
surface plasmons (LSPs). Here, we propose an effective medium which can
accurately model LSP resonances in a two-dimensional periodically decorated PEC
cylinder. The accu... | 0 | 1 | 0 | 0 | 0 | 0 |
Joint Regression and Ranking for Image Enhancement | Research on automated image enhancement has gained momentum in recent years,
partially due to the need for easy-to-use tools for enhancing pictures captured
by ubiquitous cameras on mobile devices. Many of the existing leading methods
employ machine-learning-based techniques, by which some enhancement parameters

From arteries to boreholes: Transient response of a poroelastic cylinder to fluid injection | The radially outward flow of fluid through a porous medium occurs in many
practical problems, from transport across vascular walls to the pressurisation
of boreholes in the subsurface. When the driving pressure is non-negligible
relative to the stiffness of the solid structure, the poromechanical coupling
between the... | 0 | 1 | 0 | 0 | 0 | 0 |
Social Clustering in Epidemic Spread on Coevolving Networks | Even though transitivity is a central structural feature of social networks,
its influence on epidemic spread on coevolving networks has remained relatively

triangles... | 1 | 0 | 0 | 0 | 0 | 0 |
A Mathematical Aspect of Hohenberg-Kohn Theorem | The Hohenberg-Kohn theorem plays a fundamental role in density functional
theory, which has become a basic tool for the study of electronic structure of
matter. In this article, we study the Hohenberg-Kohn theorem for a class of
external potentials based on a unique continuation principle.

Autocomplete 3D Sculpting | Digital sculpting is a popular means to create 3D models but remains a

KeyXtract Twitter Model - An Essential Keywords Extraction Model for Twitter Designed using NLP Tools | Since a tweet is limited to 140 characters, it is ambiguous and difficult for

A Generalized Zero-Forcing Precoder with Successive Dirty-Paper Coding in MISO Broadcast Channels | In this paper, we consider precoder designs for multiuser
multiple-input-single-output (MISO) broadcasting channels. Instead of using a

(GZF) precoder in conjunction with successive dirty-paper coding (DPC) for
data-transmissions, namely, the ... | 1 | 0 | 0 | 0 | 0 | 0 |
Generating Connected Random Graphs | Sampling random graphs is essential in many applications, and often
algorithms use Markov chain Monte Carlo methods to sample uniformly from the

property that we are unable, or it is too inefficient, to sample using standard
approaches. In thi... | 1 | 0 | 0 | 1 | 0 | 0 |
Machine Learning Predicts Laboratory Earthquakes | Forecasting fault failure is a fundamental but elusive goal in earthquake

New results of the search for hidden photons by means of a multicathode counter | New upper limit on a mixing parameter for hidden photons with a mass from 5

a maximal sensitivity from 10 eV till 30 eV the upper limit obtained is less

Higher dimensional Steinhaus and Slater problems via homogeneous dynamics | The three gap theorem, also known as the Steinhaus conjecture or three
