past decade. A main obstacle to their practical realization, however, is a
convincing safety concept. This question becomes ever more important as more
sophisticated algorithms are used and the vehicle automation level increases.

Semi-wavefront solutions in models of collective movements with density-dependent diffusivity | This paper deals with a nonhomogeneous scalar parabolic equation with
possibly degenerate diffusion term; the process has only one stationary state.
The equation can be interpreted as modeling collective movements (crowd
dynamics, for instance). We first prove the existence of semi-wavefront
solutions for every wave ... | 0 | 0 | 1 | 0 | 0 | 0 |
Self-Regulated Transport in Photonic Crystals with Phase-Changing Defects | Phase changing materials (PCM) are widely used for optical data recording,
sensing, all-optical switching, and optical limiting. Our focus here is on the
case when the change in the transmission characteristics of the optical
material is caused by the input light itself. Specifically, the light-induced
heating trigge... | 0 | 1 | 0 | 0 | 0 | 0 |
Assessing randomness in case assignment: the case study of the Brazilian Supreme Court | Sortition, i.e., random appointment for public duty, has been employed by
societies throughout the years, especially for duties related to the judicial
system, as a firewall designated to prevent illegitimate interference between
parties in a legal case and agents of the legal system. In judicial systems of
modern we... | 0 | 0 | 0 | 1 | 0 | 0 |
Particle picture representation of the non-symmetric Rosenblatt process and Hermite processes of any order | We provide a particle picture representation for the non-symmetric Rosenblatt
process and for Hermite processes of any order, extending the result of
Bojdecki, Gorostiza and Talarczyk in~\cite{FILT}. We show that these processes
can be obtained as limits in the sense of finite-dimensional distributions of
certain fun... | 0 | 0 | 1 | 0 | 0 | 0 |
Houdini: Fooling Deep Structured Prediction Models | Generating adversarial examples is a critical step for evaluating and
improving the robustness of learning machines. So far, most existing methods
only work for classification and are not designed to alter the true performance
measure of the problem at hand. We introduce a novel flexible approach named
Houdini for ge... | 1 | 0 | 0 | 1 | 0 | 0 |
Don't relax: early stopping for convex regularization | We consider the problem of designing efficient regularization algorithms when
regularization is encoded by a (strongly) convex functional. Unlike classical
penalization methods based on a relaxation approach, we propose an iterative
method where regularization is achieved via early stopping. Our results show
that the... | 1 | 0 | 1 | 0 | 0 | 0 |
Interplay between social influence and competitive strategical games in multiplex networks | We present a model that takes into account the coupling between evolutionary
game dynamics and social influence. Importantly, social influence and game
dynamics take place in different domains, which we model as different layers of
a multiplex network. We show that the coupling between these dynamical
processes can l... | 1 | 1 | 0 | 0 | 0 | 0 |
Data Augmentation for Low-Resource Neural Machine Translation | The quality of a Neural Machine Translation system depends substantially on
the availability of sizable parallel corpora. For low-resource language pairs
this is not the case, resulting in poor translation quality. Inspired by work
in computer vision, we propose a novel data augmentation approach that targets
low-fre... | 1 | 0 | 0 | 0 | 0 | 0 |
A Lagrangian approach to modeling heat flux driven close-contact melting | Close-contact melting refers to the process of a heat source melting its way
into a phase-change material. Of special interest is the close-contact melting
velocity, or more specifically the relative velocity between the heat source
and the phase-change material. In this work, we present a novel numerical
approach to... | 0 | 1 | 0 | 0 | 0 | 0 |
Spectral Graph Analysis: A Unified Explanation and Modern Perspectives | Complex networks or graphs are ubiquitous in sciences and engineering:
biological networks, brain networks, transportation networks, social networks,

ARMDN: Associative and Recurrent Mixture Density Networks for eRetail Demand Forecasting | Accurate demand forecasts can help on-line retail organizations better plan
their supply-chain processes. The challenge, however, is the large number of
associative factors that result in large, non-stationary shifts in demand,
which traditional time series and regression approaches fail to model. In this
paper, we p... | 0 | 0 | 0 | 1 | 0 | 0 |
Extreme Dimension Reduction for Handling Covariate Shift | In the covariate shift learning scenario, the training and test covariate
distributions differ, so that a predictor's average loss over the training and
test distributions also differ. In this work, we explore the potential of
extreme dimension reduction, i.e. to very low dimensions, in improving the

Landau-Zener transitions for Majorana fermions | One-dimensional systems obtained as low-energy limits of hybrid

Deep Hyperspherical Learning | Convolution as inner product has been the founding basis of convolutional

Robotic Pick-and-Place of Novel Objects in Clutter with Multi-Affordance Grasping and Cross-Domain Image Matching | This paper presents a robotic pick-and-place system that is capable of

of object categories without needing any task-specific training data for novel
objects. To achieve t... | 1 | 0 | 0 | 0 | 0 | 0 |
Toward an enumerative geometry with quadratic forms | We develop various aspects of classical enumerative geometry, including Euler
characteristics and formulas for counting degenerate fibres in a pencil, with
the classical numerical formulas being replaced by identitites in the
Grothendieck-Witt group of quadratic forms with coefficients in the base-field.

Robust reputation-based ranking on multipartite rating networks | The spread of online reviews, ratings and opinions and its growing influence

Duality and upper bounds in optimal stochastic control governed by partial differential equations | A dual control problem is presented for the optimal stochastic control of a

On Sampling from Massive Graph Streams | We propose Graph Priority Sampling (GPS), a new paradigm for order-based
