Efficient Algorithms for t-distributed Stochastic Neighborhood Embedding | t-distributed Stochastic Neighborhood Embedding (t-SNE) is a method for
dimensionality reduction and visualization that has become widely popular in
recent years. Efficient implementations of t-SNE are available, but they scale
poorly to datasets with hundreds of thousands to millions of high dimensional
data-points.... | 1 | 0 | 0 | 1 | 0 | 0 |
An arithmetic site of Connes-Consani type for imaginary quadratic fields with class number 1 | We construct, for imaginary quadratic number fields with class number 1, an
arithmetic site of Connes-Consani type. The main difficulty here is that the
constructions of Connes and Consani and part of their results strongly rely on
the natural order existing on real numbers which is compatible with basic
arithmetic o... | 0 | 0 | 1 | 0 | 0 | 0 |
Linear Matrix Inequalities for Physically-Consistent Inertial Parameter Identification: A Statistical Perspective on the Mass Distribution | With the increased application of model-based whole-body control in legged
robots, there has been a resurgence of research interest into methods for
accurate system identification. An important class of methods focuses on the
inertial parameters of rigid-body systems. These parameters consist of the
mass, first mass ... | 1 | 0 | 0 | 0 | 0 | 0 |
Simultaneous Block-Sparse Signal Recovery Using Pattern-Coupled Sparse Bayesian Learning | In this paper, we consider the block-sparse signals recovery problem in the
context of multiple measurement vectors (MMV) with common row sparsity
patterns. We develop a new method for recovery of common row sparsity MMV
signals, where a pattern-coupled hierarchical Gaussian prior model is
introduced to characterize ... | 1 | 0 | 0 | 1 | 0 | 0 |
A temperate rocky super-Earth transiting a nearby cool star | M dwarf stars, which have masses less than 60 per cent that of the Sun, make
up 75 per cent of the population of the stars in the Galaxy [1]. The
atmospheres of orbiting Earth-sized planets are observationally accessible via
transmission spectroscopy when the planets pass in front of these stars [2,3].

Boundary driven Brownian gas | We consider a gas of independent Brownian particles on a bounded interval in
contact with two particle reservoirs at the endpoints. Due to the Brownian
nature of the particles, infinitely many particles enter and leave the system
in each time interval. Nonetheless, the dynamics can be constructed as a Markov
process ... | 0 | 0 | 1 | 0 | 0 | 0 |
Fully Resolved Numerical Simulations of Fused Deposition Modeling. Part II-Solidification, Residual Stresses, and Modeling of the Nozzle | Purpose - This paper continues the development of a comprehensive methodology

in Part I to simulate the heat transfer and fluid dynamics of the deposition of
a polymer... | 0 | 1 | 0 | 0 | 0 | 0 |
High Dimensional Cluster Analysis Using Path Lengths | A hierarchical scheme for clustering data is presented which applies to
spaces with a high number of dimension ($N_{_{D}}>3$). The data set is first
reduced to a smaller set of partitions (multi-dimensional bins). Multiple
clustering techniques are used, including spectral clustering, however, new
techniques are also... | 1 | 0 | 0 | 0 | 0 | 0 |
Forecasting elections using compartmental models of infections | To forecast political elections, popular pollsters gather polls and combine
information from them with fundamental data such as historical trends, the
national economy, and incumbency. This process is complicated, and it includes
many subjective choices (e.g., when identifying likely voters, estimating
turnout, and q... | 1 | 0 | 0 | 0 | 0 | 0 |
Online Learning Without Prior Information | The vast majority of optimization and online learning algorithms today
require some prior information about the data (often in the form of bounds on
gradients or on the optimal parameter value). When this information is not
available, these algorithms require laborious manual tuning of various
hyperparameters, motiva... | 1 | 0 | 0 | 1 | 0 | 0 |
Sparse Identification for Nonlinear Optical Communication Systems: SINO Method | We introduce low complexity machine learning based approach for mitigating
nonlinear impairments in optical fiber communications systems. The immense

recovery of t... | 0 | 1 | 0 | 0 | 0 | 0 |
Serial Correlations in Single-Subject fMRI with Sub-Second TR | When performing statistical analysis of single-subject fMRI data, serial
correlations need to be taken into account to allow for valid inference.
Otherwise, the variability in the parameter estimates might be under-estimated
resulting in increased false-positive rates. Serial correlations in fMRI data
are commonly ch... | 0 | 0 | 0 | 1 | 0 | 0 |
Randomization-based Inference for Bernoulli-Trial Experiments and Implications for Observational Studies | We present a randomization-based inferential framework for experiments
characterized by a strongly ignorable assignment mechanism where units have
independent probabilities of receiving treatment. Previous works on
randomization tests often assume these probabilities are equal within blocks of
units. We consider the ... | 0 | 0 | 0 | 1 | 0 | 0 |
Cloaking using complementary media for electromagnetic waves | Negative index materials are artificial structures whose refractive index has

Deterministic parallel analysis: An improved method for selecting the number of factors and principal components | Factor analysis and principal component analysis (PCA) are used in many
application areas. The first step, choosing the number of components, remains a

Laplacian Spectrum of non-commuting graphs of finite groups | In this paper, we compute the Laplacian spectrum of non-commuting graphs of
some classes of finite non-abelian groups. Our computations reveal that the

Application of Coulomb energy density functional for atomic nuclei: Case studies of local density approximation and generalized gradient approximation | We test the Coulomb exchange and correlation energy density functionals of

Unsupervised prototype learning in an associative-memory network | Unsupervised learning in a generalized Hopfield associative-memory network is
