Experimental estimation of one-parameter qubit gates in the presence of phase diffusion [PDF]
, 2009 We address estimation of one-parameter qubit gates in the presence of phase diffusion. We evaluate the ultimate quantum limits to precision, seek for optimal probes and measurements, and demonstrate an optimal estimation scheme for polarization qubits ...

Compressive Parameter Estimation for Sparse Translation-Invariant Signals Using Polar Interpolation [PDF]
, 2015 We propose new compressive parameter estimation algorithms that make use of polar interpolation to improve the estimator precision. Our work extends previous approaches involving polar interpolation for compressive parameter estimation in two aspects: (i)

Robust Estimation of Optical Phase Varying as a Continuous Resonant Process [PDF]
, 2013 It is well-known that adaptive homodyne estimation of continuously varying optical phase provides superior accuracy in the phase estimate as compared to adaptive or non-adaptive static estimation.

On Improved Loss Estimation for Shrinkage Estimators
Statistical Science, 2012 Let $X$ be a random vector with distribution $P_ $ where $ $ is an unknown parameter. When estimating $ $ by some estimator $ (X)$ under a loss function $L( , )$, classical decision theory advocates that such a decision rule should be used if it has suitable properties with respect to the frequentist risk $R( , )$.

Target Association of Heterogeneous Sensors Based on Nearest-neighbor and Topology
Leida xuebao, 2012 A new data association algorithm is proposed in this paper for heterogeneous sensors information fusion system, which consists of Radar and high-dynamic-range IR, based on joint usage of the nearest-neighbor (NN) and the topology similarity. The proposed

Coherent-Classical Estimation for Linear Quantum Systems
, 2017 We study a coherent-classical estimation scheme for a class of linear quantum systems, where the estimator is a mixed quantum-classical system that may or may not involve coherent feedback.

Non-asymptotic approach to varying coefficient model [PDF]
, 2013 In the present paper we consider the varying coefficient model which represents a useful tool for exploring dynamic patterns in many applications. Existing methods typically provide asymptotic evaluation of precision of estimation procedures under the ...

M ESTIMATION, S ESTIMATION, AND MM ESTIMATION IN ROBUST REGRESSION [PDF]
International Journal of Pure and Apllied Mathematics, 2014 In regression analysis the use of least squares method would not be appropriate in solving problem containing outlier or extreme observations. So we need a parameter estimation method which is robust where the value of the estimation is not much affected by small changes in the data. In this paper we present M estimation, S estimation and MM estimation
