Utilizing Lexical Similarity between Related, Low-resource Languages for Pivot-based SMT | We investigate pivot-based translation between related languages in a low
resource, phrase-based SMT setting. We show that a subword-level pivot-based
SMT model using a related pivot language is substantially better than word and
morpheme-level pivot models. It is also highly competitive with the best direct

Multiband Electronic Structure of Magnetic Quantum Dots: Numerical Studies | Semiconductor quantum dots (QDs) doped with magnetic impurities have been a
focus of continuous research for a couple of decades. A significant effort has

Advances in Detection and Error Correction for Coherent Optical Communications: Regular, Irregular, and Spatially Coupled LDPC Code Designs | In this chapter, we show how the use of differential coding and the presence
of phase slips in the transmission channel affect the total achievable
information rates and capacity of a system. By means of the commonly used QPSK
modulation, we show that the use of differential coding does not decrease the
total amount ... | 1 | 0 | 0 | 0 | 0 | 0 |
Risk-Averse Classification | We develop a new approach to solving classification problems, which is bases
on the theory of coherent measures of risk and risk sharing ideas. The proposed
approach aims at designing a risk-averse classifier. The new approach allows
for associating distinct risk functional to each classes. The risk may be

Scattered Sentences have Few Separable Randomizations | In the paper "Randomizations of Scattered Sentences", Keisler showed that if
Martin's axiom for aleph one holds, then every scattered sentence has few
separable randomizations, and asked whether the conclusion could be proved in
ZFC alone. We show here that the answer is "yes". It follows that the absolute

Zero divisor and unit elements with support of size 4 in group algebras of torsion free groups | Kaplansky Zero Divisor Conjecture states that if $G $ is a torsion free group

G2 instantons and the Seiberg-Witten monopoles | I describe a relation (mostly conjectural) between the Seiberg-Witten
monopoles, Fueter sections, and G2 instantons. In the last part of this article
I gathered some open questions connected with this relation.

Multimodal Word Distributions | Word embeddings provide point representations of words containing useful

Gaussian mixtures, for multiple word meanings, entailment, and rich uncertainty

Efficient Policy Learning | In many areas, practitioners seek to use observational data to learn a
treatment assignment policy that satisfies application-specific constraints,
such as budget, fairness, simplicity, or other functional form constraints. For
example, policies may be restricted to take the form of decision trees based on
a limited ... | 0 | 0 | 1 | 1 | 0 | 0 |
Optimization by a quantum reinforcement algorithm | A reinforcement algorithm solves a classical optimization problem by
introducing a feedback to the system which slowly changes the energy landscape

Fast Image Processing with Fully-Convolutional Networks | We present an approach to accelerating a wide variety of image processing
operators. Our approach uses a fully-convolutional network that is trained on
input-output pairs that demonstrate the operator's action. After training, the
original operator need not be run at all. The trained network operates at full

Revealing patterns in HIV viral load data and classifying patients via a novel machine learning cluster summarization method | HIV RNA viral load (VL) is an important outcome variable in studies of HIV
infected persons. There exists only a handful of methods which classify
patients by viral load patterns. Most methods place limits on the use of viral
load measurements, are often specific to a particular study design, and do not

Superintegrable relativistic systems in spacetime-dependent background fields | We consider a relativistic charged particle in background electromagnetic

Distributed Stochastic Model Predictive Control for Large-Scale Linear Systems with Private and Common Uncertainty Sources | This paper presents a distributed stochastic model predictive control (SMPC)

Formalization of Transform Methods using HOL Light | Transform methods, like Laplace and Fourier, are frequently used for

The Velocity of the Decoding Wave for Spatially Coupled Codes on BMS Channels | We consider the dynamics of belief propagation decoding of spatially coupled

direction of a spatially coupled code develops a uniquely-shaped wave-like
solution that propa... | 1 | 0 | 1 | 0 | 0 | 0 |
In Search of an Entity Resolution OASIS: Optimal Asymptotic Sequential Importance Sampling | Entity resolution (ER) presents unique challenges for evaluation methodology.

Evidence of chaotic modes in the analysis of four delta Scuti stars | Since CoRoT observations unveiled the very low amplitude modes that form a

of this phenomenon, including the possibility of spurious signals due to the

Analytical Representations of Divisors of Integers | Certain analytical expressions which "feel" the divisors of natural numbers

On the semi-continuity problem of normalized volumes of singularities | We show that in any $\mathbb{Q}$-Gorenstein flat family of klt singularities,

Implications of right-handed neutrinos in $B-L$ extended standard model with scalar dark matter | We investigate the Standard Model (SM) with a $U(1)_{B-L}$ gauge extension
