combination of control parameters for a data miner. While widely applied in
empirical Software Engineering, there has not been much discussion on which
hyperparameter tuner is best for software analytics. To address this gap in the
literature, thi... | 1 | 0 | 0 | 0 | 0 | 0 |
Deep Generalized Canonical Correlation Analysis | We present Deep Generalized Canonical Correlation Analysis (DGCCA) -- a
method for learning nonlinear transformations of arbitrarily many views of
data, such that the resulting transformations are maximally informative of each
other. While methods for nonlinear two-view representation learning (Deep CCA,

Faithfulness of Probability Distributions and Graphs | A main question in graphical models and causal inference is whether, given a
probability distribution $P$ (which is usually an underlying distribution of
data), there is a graph (or graphs) to which $P$ is faithful. The main goal of
this paper is to provide a theoretical answer to this problem. We work with

On the multipliers of repelling periodic points of entire functions | We give a lower bound for the multipliers of repelling periodic points of
entire functions. The bound is deduced from a bound for the multipliers of
fixed points of composite entire functions.

The BCS critical temperature in a weak homogeneous magnetic field | We show that, within a linear approximation of BCS theory, a weak homogeneous
magnetic field lowers the critical temperature by an explicit constant times
the field strength, up to higher order terms. This provides a rigorous

25 Tweets to Know You: A New Model to Predict Personality with Social Media | Predicting personality is essential for social applications supporting
human-centered activities, yet prior modeling methods with users written text

Low Resolution Face Recognition Using a Two-Branch Deep Convolutional Neural Network Architecture | We propose a novel couple mappings method for low resolution face recognition
using deep convolutional neural networks (DCNNs). The proposed architecture
consists of two branches of DCNNs to map the high and low resolution face

A Comparative Study of Full-Duplex Relaying Schemes for Low Latency Applications | Various sectors are likely to carry a set of emerging applications while

Some algebraic invariants of edge ideal of circulant graphs | Let $G$ be the circulant graph $C_n(S)$ with $S\subseteq\{ 1,\ldots,\left
\lfloor\frac{n}{2}\right \rfloor\}$ and let $I(G)$ be its edge ideal in the
ring $K[x_0,\ldots,x_{n-1}]$. Under the hypothesis that $n$ is prime we : 1)

Efficient Pricing of Barrier Options on High Volatility Assets using Subset Simulation | Barrier options are one of the most widely traded exotic options on stock

Massively parallel multicanonical simulations | Generalized-ensemble Monte Carlo simulations such as the multicanonical

Gaia and VLT astrometry of faint stars: Precision of Gaia DR1 positions and updated VLT parallaxes of ultracool dwarfs | We compared positions of the Gaia first data release (DR1) secondary data set
at its faint limit with CCD positions of stars in 20 fields observed with the
VLT/FORS2 camera. The FORS2 position uncertainties are smaller than one
milli-arcsecond (mas) and allowed us to perform an independent verification of

Parallel transport in shape analysis: a scalable numerical scheme | The analysis of manifold-valued data requires efficient tools from Riemannian
geometry to cope with the computational complexity at stake. This complexity
arises from the always-increasing dimension of the data, and the absence of
closed-form expressions to basic operations such as the Riemannian logarithm.

Spectral Projector-Based Graph Fourier Transforms | The paper presents the graph Fourier transform (GFT) of a signal in terms of
its spectral decomposition over the Jordan subspaces of the graph adjacency
matrix $A$. This representation is unique and coordinate free, and it leads to
unambiguous definition of the spectral components ("harmonics") of a graph

Quantum Mechanical Approach to Modelling Reliability of Sensor Reports | Dempster-Shafer evidence theory is wildly applied in multi-sensor data

On semi-supervised learning | Semi-supervised learning deals with the problem of how, if possible, to take

Fourier dimension and spectral gaps for hyperbolic surfaces | We obtain an essential spectral gap for a convex co-compact hyperbolic
