A note on the role of projectivity in likelihood-based inference for random graph models | There is widespread confusion about the role of projectivity in

claims that projectivity, a form of marginalizability, may be necessary for
likelihood-based inference and consistency of maximum likelihood estimators. We

Evaluation of Direct Haptic 4D Volume Rendering of Partially Segmented Data for Liver Puncture Simulation | This work presents an evaluation study using a force feedback evaluation
framework for a novel direct needle force volume rendering concept in the

The Role of Big Data on Smart Grid Transition | Despite being popularly referred to as the ultimate solution for all problems
of our current electric power system, smart grid is still a growing and
unstable concept. It is usually considered as a set of advanced features
powered by promising technological solutions. In this paper, we describe smart
grid as a socio-... | 1 | 0 | 0 | 0 | 0 | 0 |
Learning Deep ResNet Blocks Sequentially using Boosting Theory | Deep neural networks are known to be difficult to train due to the
instability of back-propagation. A deep \emph{residual network} (ResNet) with
identity loops remedies this by stabilizing gradient computations. We prove a
boosting theory for the ResNet architecture. We construct $T$ weak module
classifiers, each con... | 1 | 0 | 0 | 0 | 0 | 0 |
Total energy of radial mappings | The main aim of this paper is to extend one of the main results of Iwaniec
and Onninen (Arch. Ration. Mech. Anal., 194: 927-986, 2009). We prove that, the
so called total energy functional defined on the class of radial streachings
between annuli attains its minimum on a total energy diffeomorphism between
annuli. Th... | 0 | 0 | 1 | 0 | 0 | 0 |
Divergence and Sufficiency for Convex Optimization | Logarithmic score and information divergence appear in information theory,
statistics, statistical mechanics, and portfolio theory. We demonstrate that
all these topics involve some kind of optimization that leads directly to
regret functions and such regret functions are often given by a Bregman
divergence. If the r... | 1 | 1 | 1 | 0 | 0 | 0 |
Compact linear programs for 2SAT | For each integer $n$ we present an explicit formulation of a compact linear
program, with $O(n^3)$ variables and constraints, which determines the
satisfiability of any 2SAT formula with $n$ boolean variables by a single
linear optimization. This contrasts with the fact that the natural polytope for
this problem, for... | 1 | 0 | 1 | 0 | 0 | 0 |
Distributed Protocols at the Rescue for Trustworthy Online Voting | While online services emerge in all areas of life, the voting procedure in
many democracies remains paper-based as the security of current online voting
technology is highly disputed. We address the issue of trustworthy online

assumptions. I... | 1 | 0 | 0 | 0 | 0 | 0 |
Isomonodromy aspects of the tt* equations of Cecotti and Vafa III. Iwasawa factorization and asymptotics | This paper, the third in a series, completes our description of all (radial)
solutions on C* of the tt*-Toda equations, using a combination of methods from
p.d.e., isomonodromic deformations (Riemann-Hilbert method), and loop groups.
We place these global solutions into the broader context of solutions which are

Decorative Plasmonic Surfaces | Low-profile patterned plasmonic surfaces are synergized with a broad class of

Hamiltonian approach to slip-stacking dynamics | Hamiltonian dynamics has been applied to study the slip-stacking dynamics.
The canonical-perturbation method is employed to obtain the second-harmonic

improving stack... | 0 | 1 | 0 | 0 | 0 | 0 |
Materials processing with intense pulsed ion beams and masked targets | Intense, pulsed ion beams locally heat materials and deliver dense electronic
excitations that can induce materials modifications and phase transitions.

Distributions of Historic Market Data -- Implied and Realized Volatility | We undertake a systematic comparison between implied volatility, as
represented by VIX (new methodology) and VXO (old methodology), and realized
volatility. We compare visually and statistically distributions of realized and

ratio. We find that... | 0 | 0 | 0 | 0 | 0 | 1 |
Variational Walkback: Learning a Transition Operator as a Stochastic Recurrent Net | We propose a novel method to directly learn a stochastic transition operator

Toward a language-theoretic foundation for planning and filtering | We address problems underlying the algorithmic question of automating the

we consider the impact that degradations of a robot's sensor and actuation
suites may have on the ability of that robot to complete its tasks. We

Algebraic relations between solutions of Painlevé equations | We calculate model theoretic ranks of Painlevé equations in this article,
showing in particular, that any equation in any of the Painlevé families has
Morley rank one, extending results of Nagloo and Pillay (2011). We show that
the type of the generic solution of any equation in the second Painlevé

Pore lifetimes in cell electroporation: Complex dark pores? | We review some of the basic concepts and the possible pore structures
associated with electroporation (EP) for times after electrical pulsing. We

reviews and original res... | 0 | 1 | 0 | 0 | 0 | 0 |
Data-driven causal path discovery without prior knowledge - a benchmark study | Causal discovery broadens the inference possibilities, as correlation does

dependencies. In some... | 0 | 0 | 0 | 1 | 0 | 0 |
Computation of Ground States of the Gross-Pitaevskii Functional via Riemannian Optimization | In this paper we combine concepts from Riemannian Optimization and the theory

On the symplectic size of convex polytopes | In this paper we introduce a combinatorial formula for the

capacity.
