Unique Information and Secret Key Decompositions | The unique information ($UI$) is an information measure that quantifies a
deviation from the Blackwell order. We have recently shown that this quantity
is an upper bound on the one-way secret key rate. In this paper, we prove a
triangle inequality for the $UI$, which implies that the $UI$ is never greater

Decomposition Algorithm for Distributionally Robust Optimization using Wasserstein Metric | We study distributionally robust optimization (DRO) problems where the
ambiguity set is defined using the Wasserstein metric. We show that this class
of DRO problems can be reformulated as semi-infinite programs. We give an
exchange method to solve the reformulated problem for the general nonlinear
model, and a centr... | 0 | 0 | 1 | 0 | 0 | 0 |
PD-ML-Lite: Private Distributed Machine Learning from Lighweight Cryptography | Privacy is a major issue in learning from distributed data. Recently the
cryptographic literature has provided several tools for this task. However,
these tools either reduce the quality/accuracy of the learning
algorithm---e.g., by adding noise---or they incur a high performance penalty
and/or involve trusting exter... | 1 | 0 | 0 | 1 | 0 | 0 |
ISS Property with Respect to Boundary Disturbances for a Class of Riesz-Spectral Boundary Control Systems | This paper deals with the establishment of Input-to-State Stability (ISS)

finite dimensional boundary disturbances for a class of Riesz-spectral boundary

English-Japanese Neural Machine Translation with Encoder-Decoder-Reconstructor | Neural machine translation (NMT) has recently become popular in the field of
machine translation. However, NMT suffers from the problem of repeating or
missing words in the translation. To address this problem, Tu et al. (2017)
proposed an encoder-decoder-reconstructor framework for NMT using
back-translation. In thi... | 1 | 0 | 0 | 0 | 0 | 0 |
Consistency Guarantees for Permutation-Based Causal Inference Algorithms | Bayesian networks, or directed acyclic graph (DAG) models, are widely used to
represent complex causal systems. Since the basic task of learning a Bayesian
network from data is NP-hard, a standard approach is greedy search over the
space of DAGs or Markov equivalent DAGs. Since the space of DAGs on p nodes and

TriviaQA: A Large Scale Distantly Supervised Challenge Dataset for Reading Comprehension | We present TriviaQA, a challenging reading comprehension dataset containing

evidence documents, six per question on average, that provide high quality
distant supervision f... | 1 | 0 | 0 | 0 | 0 | 0 |
Optimizing Node Discovery on Networks: Problem Definitions, Fast Algorithms, and Observations | Many people dream to become famous, YouTube video makers also wish their
videos to have a large audience, and product retailers always hope to expose
their products to customers as many as possible. Do these seemingly different

could be m... | 1 | 0 | 0 | 0 | 0 | 0 |
Some properties of h-MN-convexity and Jensen's type inequalities | In this work, we introduce the class of $h$-${\rm{MN}}$-convex functions by
generalizing the concept of ${\rm{MN}}$-convexity and combining it with
$h$-convexity. Namely, Let $I,J$ be two intervals subset of
$\left(0,\infty\right)$ such that $\left(0,1\right)\subseteq J$ and
$\left[a,b\right]\subseteq I$. Consider a ... | 0 | 0 | 1 | 0 | 0 | 0 |
Impact of Traditional Sparse Optimizations on a Migratory Thread Architecture | Achieving high performance for sparse applications is challenging due to
irregular access patterns and weak locality. These properties preclude many
static optimizations and degrade cache performance on traditional systems. To
address these challenges, novel systems such as the Emu architecture have been
proposed. Th... | 1 | 0 | 0 | 0 | 0 | 0 |
Finding Bottlenecks: Predicting Student Attrition with Unsupervised Classifier | With pressure to increase graduation rates and reduce time to degree in

Chemical evolution of 244Pu in the solar vicinity and its implication for the properties of r-process production | Meteoritic abundances of r-process elements are analyzed to deduce the

formation to the present time in the solar vicinity, by combining the abundance
information from short-lived radioactive nuclei such as 244Pu with that from

SAVITR: A System for Real-time Location Extraction from Microblogs during Emergencies | We present SAVITR, a system that leverages the information posted on the

that only a very small percentage of microblogs are geo-tagged, it is essential
for such a system to extract locations from the text of the microblogs. We

Fractional Driven Damped Oscillator | The resonances associated with a fractional damped oscillator which is driven
by an oscillatory external force are studied. It is shown that such resonances
can be manipulated by tuning up either the coefficient of the fractional
damping or the order of the corresponding fractional derivatives.

Bootstrap confidence sets for spectral projectors of sample covariance | Let $X_{1},\ldots,X_{n}$ be i.i.d. sample in $\mathbb{R}^{p}$ with zero mean

Locally recoverable codes from algebraic curves and surfaces | A locally recoverable code is a code over a finite alphabet such that the

An Infinite Hidden Markov Model With Similarity-Biased Transitions | We describe a generalization of the Hierarchical Dirichlet Process Hidden
