Single Magnetic Impurity in Tilted Dirac Surface States | We utilize variational method to investigate the Kondo screening of a
spin-1/2 magnetic impurity in tilted Dirac surface states with the Dirac cone
tilted along the $k_y$-axis. We mainly study about the effect of the tilting

Leveraging the Path Signature for Skeleton-based Human Action Recognition | Human action recognition in videos is one of the most challenging tasks in
computer vision. One important issue is how to design discriminative features
for representing spatial context and temporal dynamics. Here, we introduce a
path signature feature to encode information from intra-frame and inter-frame
contexts. ... | 1 | 0 | 0 | 0 | 0 | 0 |
How Many Subpopulations is Too Many? Exponential Lower Bounds for Inferring Population Histories | Reconstruction of population histories is a central problem in population
genetics. Existing coalescent-based methods, like the seminal work of Li and
Durbin (Nature, 2011), attempt to solve this problem using sequence data but
have no rigorous guarantees. Determining the amount of data needed to correctly

Source localization in an ocean waveguide using supervised machine learning | Source localization in ocean acoustics is posed as a machine learning problem
in which data-driven methods learn source ranges directly from observed
acoustic data. The pressure received by a vertical linear array is preprocessed
by constructing a normalized sample covariance matrix (SCM) and used as the
input. Three... | 1 | 1 | 0 | 0 | 0 | 0 |
Mining Illegal Insider Trading of Stocks: A Proactive Approach | Illegal insider trading of stocks is based on releasing non-public
information (e.g., new product launch, quarterly financial report, acquisition
or merger plan) before the information is made public. Detecting illegal
insider trading is difficult due to the complex, nonlinear, and non-stationary
nature of the stock ... | 0 | 0 | 0 | 1 | 0 | 1 |
Discovery of Extreme [OIII]+H$β$ Emitting Galaxies Tracing an Overdensity at z~3.5 in CDF-South | Using deep multi-wavelength photometry of galaxies from ZFOURGE, we group
galaxies at $2.5<z<4.0$ by the shape of their spectral energy distributions
(SEDs). We identify a population of galaxies with excess emission in the
$K_s$-band, which corresponds to [OIII]+H$\beta$ emission at $2.95<z<3.65$.

Learning to attend in a brain-inspired deep neural network | Recent machine learning models have shown that including attention as a

Anisotropic functional Laplace deconvolution | In the present paper we consider the problem of estimating a

Prediction of many-electron wavefunctions using atomic potentials | For a given many-electron molecule, it is possible to define a corresponding

Free energy of formation of a crystal nucleus in incongruent solidification: Implication for modeling the crystallization of aqueous nitric acid droplets in type 1 polar stratospheric clouds | Using the formalism of the classical nucleation theory, we derive an

Ensemble learning with Conformal Predictors: Targeting credible predictions of conversion from Mild Cognitive Impairment to Alzheimer's Disease | Most machine learning classifiers give predictions for new examples

Repair Strategies for Storage on Mobile Clouds | We study the data reliability problem for a community of devices forming a
