The Horseshoe+ Estimator of Ultra-Sparse Signals [PDF]
, 2015 We propose a new prior for ultra-sparse signal detection that we term the "horseshoe+ prior." The horseshoe+ prior is a natural extension of the horseshoe prior that has achieved success in the estimation and detection of sparse signals and has been ...

Non-Data-Aided Parameter Estimation in an Additive White Gaussian Noise Channel
, 2005 Non-data-aided (NDA) parameter estimation is considered for binary-phase-shift-keying transmission in an additive white Gaussian noise channel. Cramer-Rao lower bounds (CRLBs) for signal amplitude, noise variance, channel reliability constant and bit ...

A Survey on Vision Navigation Methods for UAV Navigation Applications [PDF]
فصلنامه علوم و فناوری فضایی, 2017 Inertial navigation system error increases due to sensor errors with the increase intime. Usually, to prevent the growth of navigation system error, inertial navigationsystems are integrated with sensors or auxiliary systems. The importantly aided system

Confidence intervals in regression centred on the SCAD estimator
, 2012 Consider a linear regression model. Fan and Li (2001) describe the smoothly clipped absolute deviation (SCAD) point estimator of the regression parameter vector.

An Artificial Neural Network for the Low-Cost Prediction of Soot Emissions
Energies, 2020 Soot formation in combustion systems is a growing concern due to its adverse environmental and health effects. It is considered to be a tremendously complicated phenomenon which includes multiphase flow, thermodynamics, heat transfer, chemical kinetics ...

The Horseshoe Estimator: Posterior Concentration around Nearly Black Vectors [PDF]
, 2014 We consider the horseshoe estimator due to Carvalho, Polson and Scott (2010) for the multivariate normal mean model in the situation that the mean vector is sparse in the nearly black sense. We assume the frequentist framework where the data is generated

The horseshoe estimator for sparse signals
, 2010 This paper proposes a new approach to sparsity, called the horseshoe estimator, which arises from a prior based on multivariate-normal scale mixtures. We describe the estimator's advantages over existing approaches, including its robustness, adaptivity ...

, 2015 The aim of this article is to propose a novel kernel estimator of the baseline function in a general high-dimensional Cox model, for which we derive non-asymptotic rates of convergence.
