neural network (3-D-CNN) to fuse together multispectral (MS) and hyperspectral
(HS) images to obtain a high resolution hyperspectral image. Dimensionality
reduction of the hyperspectral image is performed prior to fusion in order to

The fundamental Lepage form in variational theory for submanifolds | A setting for global variational geometry on Grassmann fibrations is
presented. The integral variational functionals for finite dimensional immersed
submanifolds are studied by means of the fundamental Lepage equivalent of a
homogeneous Lagrangian, which can be regarded as a generalization of the
well-known Hilbert f... | 0 | 0 | 1 | 0 | 0 | 0 |
Adding educational funcionalities to classic board games | In this paper we revisit some classic board games like Pachisi or the Game of
Gosse. The main contribution of the paper is to design and add some
functionalities to the games in order to transform them in serious games, that
is, in games with learning and educational purposes. To do that, at the
beginning of the game... | 1 | 0 | 0 | 0 | 0 | 0 |
Conceptual Frameworks for Building Online Citizen Science Projects | In recent years, citizen science has grown in popularity due to a number of
reasons, including the emphasis on informal learning and creativity potential
associated with these initiatives. Citizen science projects address research

advanceme... | 1 | 0 | 0 | 0 | 0 | 0 |
SDN Architecture and Southbound APIs for IPv6 Segment Routing Enabled Wide Area Networks | The SRv6 architecture (Segment Routing based on IPv6 data plane) is a
promising solution to support services like Traffic Engineering, Service
Function Chaining and Virtual Private Networks in IPv6 backbones and

Topology-optimized Dual-Polarization Dirac Cones | We apply a large-scale computational technique, known as topology
optimization, to the inverse design of photonic Dirac cones. In particular, we
report on a variety of photonic crystal geometries, realizable in simple
isotropic dielectric materials, which exhibit dual-polarization and
dual-wavelength Dirac cones. We ... | 0 | 1 | 0 | 0 | 0 | 0 |
Reconstruction of Word Embeddings from Sub-Word Parameters | Pre-trained word embeddings improve the performance of a neural model at the
cost of increasing the model size. We propose to benefit from this resource
without paying the cost by operating strictly at the sub-lexical level. Our
approach is quite simple: before task-specific training, we first optimize
sub-word param... | 1 | 0 | 0 | 0 | 0 | 0 |
Deep Submodular Functions | We start with an overview of a class of submodular functions called SCMMs
(sums of concave composed with non-negative modular functions plus a final
arbitrary modular). We then define a new class of submodular functions we call
{\em deep submodular functions} or DSFs. We show that DSFs are a flexible
parametric famil... | 1 | 0 | 0 | 0 | 0 | 0 |
Inverse problems for the wave equation with under-determined data | We consider the inverse problems of determining the potential or the damping
coefficient appearing in the wave equation. We will prove the unique
determination of these coefficients from the one point measurement. Since our
problem is under-determined, so some extra assumption on the coefficients is
required to prove... | 0 | 0 | 1 | 0 | 0 | 0 |
Spatial interactions and oscillatory tragedies of the commons | A tragedy of the commons (TOC) occurs when individuals acting in their own
self-interest deplete commonly-held resources, leading to a worse outcome than
had they cooperated. Over time, the depletion of resources can change
incentives for subsequent actions. Here, we investigate long-term feedback
between game and en... | 0 | 0 | 0 | 0 | 1 | 0 |
An upper bound on transport | The linear growth of operators in local quantum systems leads to an effective
lightcone even if the system is non-relativistic. We show that consistency of
diffusive transport with this lightcone places an upper bound on the
diffusivity: $D \lesssim v^2 \tau_\text{eq}$. The operator growth velocity $v$
defines the li... | 0 | 1 | 0 | 0 | 0 | 0 |
Taylor expansion in linear logic is invertible | Each Multiplicative Exponential Linear Logic (MELL) proof-net can be expanded
into a differential net, which is its Taylor expansion. We prove that two
different MELL proof-nets have two different Taylor expansions. As a corollary,
we prove a completeness result for MELL: We show that the relational model is

Collision-Free Multi Robot Trajectory Optimization in Unknown Environments using Decentralized Trajectory Planning | Multi robot systems have the potential to be utilized in a variety of
applications. In most of the previous works, the trajectory generation for
multi robot systems is implemented in known environments. To overcome that we
present an online trajectory optimization algorithm that utilizes communication
of robots' curr... | 1 | 0 | 0 | 0 | 0 | 0 |
On the bottom of spectra under coverings | For a Riemannian covering $M_1\to M_0$ of complete Riemannian manifolds with
boundary (possibly empty) and respective fundamental groups
$\Gamma_1\subseteq\Gamma_0$, we show that the bottoms of the spectra of $M_0$
and $M_1$ coincide if the right action of $\Gamma_0$ on
$\Gamma_1\backslash\Gamma_0$ is amenable.

Theory of ground states for classical Heisenberg spin systems IV | We extend the theory of ground states of classical Heisenberg spin systems

magnetic field is described by a Zeeman term. The ground state problem for the
Heisenberg-Zeeman Hamiltonian can be reduced first to the relative ground state
problem, and... | 0 | 1 | 0 | 0 | 0 | 0 |
Aggressive Deep Driving: Model Predictive Control with a CNN Cost Model | We present a framework for vision-based model predictive control (MPC) for

K-theory of line bundles and smooth varieties | We give a $K$-theoretic criterion for a quasi-projective variety to be
smooth. If $\mathbb{L}$ is a line bundle corresponding to an ample invertible
sheaf on $X$, it suffices that $K_q(X) = K_q(\mathbb{L})$ for all
$q\le\dim(X)+1$.

Local Two-Sample Testing: A New Tool for Analysing High-Dimensional Astronomical Data | Modern surveys have provided the astronomical community with a flood of
high-dimensional data, but analyses of these data often occur after their
projection to lower-dimensional spaces. In this work, we introduce a local
two-sample hypothesis test framework that an analyst may directly apply to data
in their native s... | 0 | 1 | 0 | 0 | 0 | 0 |
Are You Tampering With My Data? | We propose a novel approach towards adversarial attacks on neural networks
(NN), focusing on tampering the data used for training instead of generating
attacks on trained models. Our network-agnostic method creates a backdoor
during training which can be exploited at test time to force a neural network
to exhibit abn... | 0 | 0 | 0 | 1 | 0 | 0 |
Answering Spatial Multiple-Set Intersection Queries Using 2-3 Cuckoo Hash-Filters | We show how to answer spatial multiple-set intersection queries in O(n(log

the query, w is the number of bits in a memory word, k is the output size, and
c is any fixed constant. This improves the asymptotic performance over previous

A framework for cascade size calculations on random networks | We present a framework to calculate the cascade size evolution for a large

threshold mod... | 1 | 1 | 0 | 0 | 0 | 0 |
A Gaussian Process Regression Model for Distribution Inputs | Monge-Kantorovich distances, otherwise known as Wasserstein distances, have
