Deep Learning with Low Precision by Half-wave Gaussian Quantization | The problem of quantizing the activations of a deep neural network is
considered. An examination of the popular binary quantization approach shows
that this consists of approximating a classical non-linearity, the hyperbolic
tangent, by two functions: a piecewise constant sign function, which is used in
feedforward n... | 1 | 0 | 0 | 0 | 0 | 0 |
Degenerate cyclotomic Hecke algebras and higher level Heisenberg categorification | We associate a monoidal category $\mathcal{H}^\lambda$ to each dominant
integral weight $\lambda$ of $\widehat{\mathfrak{sl}}_p$ or
$\mathfrak{sl}_\infty$. These categories, defined in terms of planar diagrams,
act naturally on categories of modules for the degenerate cyclotomic Hecke
algebras associated to $\lambda$... | 0 | 0 | 1 | 0 | 0 | 0 |
Intense automorphisms of finite groups | Let $G$ be a group. An automorphism of $G$ is called intense if it sends each
subgroup of $G$ to a conjugate; the collection of such automorphisms is denoted
by $\mathrm{Int}(G)$. In the special case in which $p$ is a prime number and
$G$ is a finite $p$-group, one can show that $\mathrm{Int}(G)$ is the

The spectra of harmonic layer potential operators on domains with rotationally symmetric conical points | We study the adjoint of the double layer potential associated with the
Laplacian (the adjoint of the Neumann-Poincaré operator), as a map on the
boundary surface $\Gamma$ of a domain in $\mathbb{R}^3$ with conical points.
The spectrum of this operator directly reflects the well-posedness of related

Experimental Determination of the Structural Coefficient of Restitution of a Bouncing Asteroid Lander | The structural coefficient of restitution describes the kinetic energy
dissipation upon low-velocity (~0.1 m/s) impact of a small asteroid lander,
MASCOT, against a hard, ideally elastic plane surface. It is a crucial
worst-case input for mission analysis for landing MACOT on a 1km asteroid in
2018. We conducted pend... | 0 | 1 | 0 | 0 | 0 | 0 |
Onset of a modulational instability in trapped dipolar Bose-Einstein condensates | We explore the phase diagram of a finite-sized dysprosium dipolar
Bose-Einstein condensate in a cylindrical harmonic trap. We monitor the final

the quantum droplet regime. Either an adiabatic transformation between a BEC
and a quantum dropl... | 0 | 1 | 0 | 0 | 0 | 0 |
Visual Detection of Structural Changes in Time-Varying Graphs Using Persistent Homology | Topological data analysis is an emerging area in exploratory data analysis

technique to study the structure of complex, high-dimensional data. In this
paper, we propose a novel method using persistent homology to quantify
structural changes in ... | 1 | 0 | 0 | 0 | 0 | 0 |
Controller Synthesis for Discrete-Time Polynomial Systems via Occupation Measures | In this paper, we design nonlinear state feedback controllers for
discrete-time polynomial dynamical systems via the occupation measure approach.
We propose the discrete-time controlled Liouville equation, and use it to

programming problem o... | 1 | 0 | 0 | 0 | 0 | 0 |
Lose The Views: Limited Angle CT Reconstruction via Implicit Sinogram Completion | Computed Tomography (CT) reconstruction is a fundamental component to a wide
variety of applications ranging from security, to healthcare. The classical
techniques require measuring projections, called sinograms, from a full

scenario, when the vie... | 0 | 0 | 0 | 1 | 0 | 0 |
A three-dimensional symmetry result for a phase transition equation in the genuinely nonlocal regime | We consider bounded solutions of the nonlocal Allen-Cahn equation $$
(-\Delta)^s u=u-u^3\qquad{\mbox{ in }}{\mathbb{R}}^3,$$ under the monotonicity
condition $\partial_{x_3}u>0$ and in the genuinely nonlocal regime in

The growth of bismuth on Bi$_2$Se$_3$ and the stability of the first bilayer | Bi(0001) films with thicknesses up to several bilayers (BLs) are grown on
Se-terminated Bi$_2$Se$_3$(0001) surfaces, and low energy electron diffraction
(LEED), low energy ion scattering (LEIS) and atomic force microscopy (AFM) are

Introduction to Tensor Decompositions and their Applications in Machine Learning | Tensors are multidimensional arrays of numerical values and therefore
generalize matrices to multiple dimensions. While tensors first emerged in the
psychometrics community in the $20^{\text{th}}$ century, they have since then
spread to numerous other disciplines, including machine learning. Tensors and
their decompo... | 1 | 0 | 0 | 1 | 0 | 0 |
Sampling-based vs. Design-based Uncertainty in Regression Analysis | Consider a researcher estimating the parameters of a regression function
based on data for all 50 states in the United States or on data for all visits
to a website. What is the interpretation of the estimated parameters and the
standard errors? In practice, researchers typically assume that the sample is
randomly dr... | 0 | 0 | 1 | 1 | 0 | 0 |
Scalable Joint Models for Reliable Uncertainty-Aware Event Prediction | Missing data and noisy observations pose significant challenges for reliably
predicting events from irregularly sampled multivariate time series
(longitudinal) data. Imputation methods, which are typically used for
completing the data prior to event prediction, lack a principled mechanism to
account for the uncertain... | 1 | 0 | 0 | 1 | 0 | 0 |
Concurrent Coding: A Reason to Think Differently About Encoding Against Noise, Burst Errors and Jamming | Concurrent coding is an unconventional encoding technique that simultaneously
provides protection against noise, burst errors and interference. This
simple-to-understand concept is investigated by distinguishing 2 types of code,
open and closed, with the majority of the investigation concentrating on closed
codes. Co... | 1 | 0 | 0 | 0 | 0 | 0 |
Traveling dark-bright solitons in a reduced spin-orbit coupled system: application to Bose-Einstein condensates | In the present work, we explore the potential of spin-orbit (SO) coupled
Bose-Einstein condensates to support multi-component solitonic states in the

between components is absent, we use a multiscale expansion method to reduce

On methods to determine bounds on the Q-factor for a given directivity | This paper revisit and extend the interesting case of bounds on the Q-factor
for a given directivity for a small antenna of arbitrary shape. A higher

bandwidth. The relation between bandwidth and a desired directivity is still
not fully under... | 0 | 1 | 1 | 0 | 0 | 0 |
Nano-optical imaging of monolayer MoSe2 using tip-enhanced photoluminescence | Band gap tuning in two-dimensional transitional metal dichalcogenides (TMDs)

The sequential loss of allelic diversity | This paper gives a new flavor of what Peter Jagers and his co-authors call

Online classification of imagined speech using functional near-infrared spectroscopy signals | Most brain-computer interfaces (BCIs) based on functional near-infrared
