Abstract: During the flyby in 2010, the OSIRIS camera on-board Rosetta acquired
hundreds of high-resolution images of asteroid Lutetia's surface through a
range of narrow-band filters. While Lutetia appears very bland in the visible
wavelength range, Magri... | [

Title: Rokhlin dimension for compact quantum group actions,
Abstract: We show that, for a given compact or discrete quantum group $G$, the class of
actions of $G$ on C*-algebras is first-order axiomatizable in the logic for
metric structures. As an application, we extend the notion of Rokhlin property
for $G$-C*-algebr... | [

Title: Parametric Identification Using Weighted Null-Space Fitting,
Abstract: In identification of dynamical systems, the prediction error method using a
quadratic cost function provides asymptotically efficient estimates under
Gaussian noise and additional mild assumptions, but in general it requires
solving a non-con... | [

Title: Learning Large-Scale Bayesian Networks with the sparsebn Package,
Abstract: Learning graphical models from data is an important problem with wide
applications, ranging from genomics to the social sciences. Nowadays datasets
often have upwards of thousands---sometimes tens or hundreds of thousands---of
variables ... | [

Title: An Asymptotically Optimal Index Policy for Finite-Horizon Restless Bandits,
Abstract: We consider restless multi-armed bandit (RMAB) with a finite horizon and
multiple pulls per period. Leveraging the Lagrangian relaxation, we approximate
the problem with a collection of single arm problems. We then propose an

Title: Effective holographic theory of charge density waves,
Abstract: We use Gauge/Gravity duality to write down an effective low energy
holographic theory of charge density waves. We consider a simple gravity model
which breaks translations spontaneously in the dual field theory in a
homogeneous manner, capturing the... | [

Title: Interactive Certificates for Polynomial Matrices with Sub-Linear Communication,

verify concern an F[x]-module and therefore cannot simply rely on
previousl... | [

Title: Cost Functions for Robot Motion Style,
Abstract: We focus on autonomously generating robot motion for day to day physical
tasks that is expressive of a certain style or emotion. Because we seek
generalization across task instances and task types, we propose to capture
style via cost functions that the robot can ... | [

orbit, and the tertia... | [

Title: A more symmetric picture for Kasparov's KK-bifunctor,
Abstract: For C*-algebras $A$ and $B$, we generalize the notion of a quasihomomorphism
from $A$ to $B$, due to Cuntz, by considering quasihomomorphisms from some
C*-algebra $C$ to $B$ such that $C$ surjects onto $A$, and the two maps forming
a quasihomomorphi... | [
