Generic Axiomatization of Families of Noncrossing Graphs in Dependency Parsing | We present a simple encoding for unlabeled noncrossing graphs and show how
its latent counterpart helps us to represent several families of directed and
undirected graphs used in syntactic and semantic parsing of natural language as
context-free languages. The families are separated purely on the basis of
forbidden p... | 1 | 0 | 0 | 0 | 0 | 0 |
Computation of Optimal Transport on Discrete Metric Measure Spaces | In this paper we investigate the numerical approximation of an analogue of
the Wasserstein distance for optimal transport on graphs that is defined via a
discrete modification of the Benamou--Brenier formula. This approach involves
the logarithmic mean of measure densities on adjacent nodes of the graph. For
this mod... | 0 | 0 | 1 | 0 | 0 | 0 |
Torsions of integral homology and cohomology of real Grassmannians | According to a result of Ehresmann, the torsions of integral homology of real
Grassmannian are all of order $2$. In this note, We compute the
$\mathbb{Z}_2$-dimensions of torsions in the integral homology and cohomology
of real Grassmannian.

PACO: Signal Restoration via PAtch COnsensus | Many signal processing algorithms operate by breaking the target signal into
possibly overlapping segments (typically called windows or patches), processing
them separately, and then stitching them back into place to produce a unified
output. In most cases where pach overlapping occurs, the final value of those
sampl... | 0 | 0 | 0 | 1 | 0 | 0 |
Hyperplane arrangements associated to symplectic quotient singularities | We study the hyperplane arrangements associated, via the minimal model
programme, to symplectic quotient singularities. We show that this hyperplane
arrangement equals the arrangement of CM-hyperplanes coming from the

some of the interesting ... | 0 | 0 | 1 | 0 | 0 | 0 |
CTCModel: a Keras Model for Connectionist Temporal Classification | We report an extension of a Keras Model, called CTCModel, to perform the
Connectionist Temporal Classification (CTC) in a transparent way. Combined with
Recurrent Neural Networks, the Connectionist Temporal Classification is the

that are a ... | 1 | 0 | 0 | 1 | 0 | 0 |
Software Distribution Transparency and Auditability | A large user base relies on software updates provided through package
managers. This provides a unique lever for improving the security of the

system is capable ... | 1 | 0 | 0 | 0 | 0 | 0 |
Imputation Approaches for Animal Movement Modeling | The analysis of telemetry data is common in animal ecological studies. While
the collection of telemetry data for individual animals has improved
dramatically, the methods to properly account for inherent uncertainties (e.g.,
measurement error, dependence, barriers to movement) have lagged behind. Still,
many new sta... | 0 | 0 | 0 | 1 | 0 | 0 |
Motion planning in high-dimensional spaces | Motion planning is a key tool that allows robots to navigate through an

degree-of-freedom (DOF) robot... | 1 | 0 | 0 | 0 | 0 | 0 |
Emergent low-energy bound states in the two-orbital Hubbard model | A repulsive Coulomb interaction between electrons in different orbitals in

Improved thermal lattice Boltzmann model for simulation of liquid-vapor phase change | In this paper, an improved thermal lattice Boltzmann (LB) model is proposed
for simulating liquid-vapor phase change, which is aimed at improving an
existing thermal LB model for liquid-vapor phase change [S. Gong and P. Cheng,
Int. J. Heat Mass Transfer 55, 4923 (2012)]. First, we emphasize that the

A fresh look at effect aliasing and interactions: some new wine in old bottles | Interactions and effect aliasing are among the fundamental concepts in
experimental design. In this paper, some new insights and approaches are
provided on these subjects. In the literature, the "de-aliasing" of aliased
effects is deemed to be impossible. We argue that this "impossibility" can
indeed be resolved by e... | 0 | 0 | 0 | 1 | 0 | 0 |
Effects of sampling skewness of the importance-weighted risk estimator on model selection | Importance-weighting is a popular and well-researched technique for dealing
with sample selection bias and covariate shift. It has desirable
characteristics such as unbiasedness, consistency and low computational
complexity. However, weighting can have a detrimental effect on an estimator as
well. In this work, we em... | 0 | 0 | 0 | 1 | 0 | 0 |
Minimizing the Cost of Team Exploration | A group of mobile agents is given a task to explore an edge-weighted graph

is no centralized unit to coordinate their actions, but they can freely
communicate with each other. The goal is to construct a deterministic strategy
which allows a... | 1 | 0 | 0 | 0 | 0 | 0 |
Exponential Source/Channel Duality | We propose a source/channel duality in the exponential regime, where
success/failure in source coding parallels error/correctness in channel coding,
and a distortion constraint becomes a log-likelihood ratio (LLR) threshold. We
establish this duality by first deriving exact exponents for lossy coding of a

Delta Theorem in the Age of High Dimensions | We provide a new version of delta theorem, that takes into account of high
dimensional parameter estimation. We show that depending on the structure of
the function, the limits of functions of estimators have faster or slower rate
of convergence than the limits of estimators. We illustrate this via two
examples. Firs... | 0 | 0 | 1 | 1 | 0 | 0 |
Deep Learning Interior Tomography for Region-of-Interest Reconstruction | Interior tomography for the region-of-interest (ROI) imaging has advantages
of using a small detector and reducing X-ray radiation dose. However, standard

reconstruction me... | 1 | 0 | 0 | 1 | 0 | 0 |
Structured Parallel Programming for Monte Carlo Tree Search | In this paper, we present a new algorithm for parallel Monte Carlo tree

MCTS. Moreover, we p... | 1 | 0 | 0 | 0 | 0 | 0 |
Single-Atom Scale Structural Selectivity in Te Nanowires Encapsulated inside Ultra-Narrow, Single-Walled Carbon Nanotubes | Extreme nanowires (ENs) represent the ultimate class of crystals: They are
