Planar Graph Perfect Matching is in NC | Is perfect matching in NC? That is, is there a deterministic fast parallel
algorithm for it? This has been an outstanding open question in theoretical
computer science for over three decades, ever since the discovery of RNC
matching algorithms. Within this question, the case of planar graphs has
remained an enigma: O... | 1 | 0 | 0 | 0 | 0 | 0 |
Recommendation under Capacity Constraints | In this paper, we investigate the common scenario where every candidate item
for recommendation is characterized by a maximum capacity, i.e., number of
seats in a Point-of-Interest (POI) or size of an item's inventory. Despite the
prevalence of the task of recommending items under capacity constraints in a
variety of... | 1 | 0 | 0 | 1 | 0 | 0 |
Simulation to scaled city: zero-shot policy transfer for traffic control via autonomous vehicles | Using deep reinforcement learning, we train control policies for autonomous
vehicles leading a platoon of vehicles onto a roundabout. Using Flow, a library
for deep reinforcement learning in micro-simulators, we train two policies, one
policy with noise injected into the state and action space and one without any
inj... | 1 | 0 | 0 | 0 | 0 | 0 |
Relative Singularity Categories | We study the following generalization of singularity categories. Let X be a
quasi-projective Gorenstein scheme with isolated singularities and A a
non-commutative resolution of singularities of X in the sense of Van den Bergh.
We introduce the relative singularity category as the Verdier quotient of the
bounded deriv... | 0 | 0 | 1 | 0 | 0 | 0 |
Challenges to Keeping the Computer Industry Centered in the US | It is undeniable that the worldwide computer industry's center is the US,
specifically in Silicon Valley. Much of the reason for the success of Silicon
Valley had to do with Moore's Law: the observation by Intel co-founder Gordon
Moore that the number of transistors on a microchip doubled at a rate of
approximately e... | 1 | 0 | 0 | 0 | 0 | 0 |
Contiguous Relations, Laplace's Methods and Continued Fractions for 3F2(1) | Using contiguous relations we construct an infinite number of continued
fraction expansions for ratios of generalized hypergeometric series 3F2(1). We
establish exact error term estimates for their approximants and prove their
rapid convergences. To do so we develop a discrete version of Laplace's method
for hypergeo... | 0 | 0 | 1 | 0 | 0 | 0 |
Arimoto-Rényi Conditional Entropy and Bayesian $M$-ary Hypothesis Testing | This paper gives upper and lower bounds on the minimum error probability of
Bayesian $M$-ary hypothesis testing in terms of the Arimoto-Rényi conditional
entropy of an arbitrary order $\alpha$. The improved tightness of these bounds
over their specialized versions with the Shannon conditional entropy
($\alpha=1$) is ... | 1 | 0 | 1 | 1 | 0 | 0 |
A note on the violation of Bell's inequality | With Bell's inequalities one has a formal expression to show how essentially
all local theories of natural phenomena that are formulated within the

measurement se... | 0 | 1 | 0 | 0 | 0 | 0 |
Real-Time Model Predictive Control for Energy Management in Autonomous Underwater Vehicle | Improving endurance is crucial for extending the spatial and temporal
operation range of autonomous underwater vehicles (AUVs). Considering the

Surjective H-Colouring over Reflexive Digraphs | The Surjective H-Colouring problem is to test if a given graph allows a
vertex-surjective homomorphism to a fixed graph H. The complexity of this
problem has been well studied for undirected (partially) reflexive graphs. We
introduce endo-triviality, the property of a structure that all of its
endomorphisms that do n... | 1 | 0 | 0 | 0 | 0 | 0 |
A modal typing system for self-referential programs and specifications | This paper proposes a modal typing system that enables us to handle

on one hand, would introduce a logical contradiction, namely Russell's paradox,

Scalable Realistic Recommendation Datasets through Fractal Expansions | Recommender System research suffers currently from a disconnect between the
size of academic data sets and the scale of industrial production systems. In

incidence matrice... | 1 | 0 | 0 | 1 | 0 | 0 |
Implementation of a Distributed Coherent Quantum Observer | This paper considers the problem of implementing a previously proposed

Stacking and stability | Stacking is a general approach for combining multiple models toward greater

Accelerating Discrete Wavelet Transforms on GPUs | The two-dimensional discrete wavelet transform has a huge number of

this paper, we... | 1 | 0 | 0 | 0 | 0 | 0 |
Accelerated Consensus via Min-Sum Splitting | We apply the Min-Sum message-passing protocol to solve the consensus problem

Constraining the Milky Way assembly history with Galactic Archaeology. Ludwig Biermann Award Lecture 2015 | The aim of Galactic Archaeology is to recover the evolutionary history of the

not sufficient for this task. The chemical composition of stellar atmospheres,

A unified view of entropy-regularized Markov decision processes | We propose a general framework for entropy-regularized average-reward

that using th... | 1 | 0 | 0 | 1 | 0 | 0 |
Arithmetic Circuits for Multilevel Qudits Based on Quantum Fourier Transform | We present some basic integer arithmetic quantum circuits, such as adders and

an alternative basis after they have been Fourier transformed. Several
