Guaranteed Error Bounds for Model Reduction of Linear Time-Varying Systems
Time-Varying Systems Model Reduction
2015/6/19
New techniques are presented for the model reduction of linear time-varying and linear periodically-varying systems, including the formulation and proof of guaranteed upper bounds for the error. The c...
Error Bounds for Balanced Model Reduction of Linear Time-Varying Systems
Time-Varying Systems Model Reduction
2015/6/19
Error-bounds are developed for balanced truncation of linear time-varying systems, leading to an extension of the `twice the sum of the tail' formulae, well-known in the time-invariant case. The appro...
A computability challenge: asymptotic bounds and isolated error-correcting codes
asymptotic bounds isolated error-correcting codes Information Theory
2011/9/16
Abstract: Consider the set of all error--correcting block codes over a fixed alphabet with $q$ letters. It determines a recursively enumerable set of points in the unit square with coordinates $(R,\de...
The Sender-Excited Secret Key Agreement Model: Capacity and Error Exponents
Secret key capacity Common randomness Wiretap channel Sender-excitation Reliability exponent Secrecy exponent
2011/9/16
Abstract: We consider fundamental limits of the secret key generation problem when the sources are randomly excited by the sender and there is a noiseless public discussion channel. In many practical ...
A Generalized Poor-Verdu Error Bound for Multihypothesis Testing and the Channel Reliability Function
Hypothesis testing probability of error maximum-a-posteriori and maximum likelihood estimation channel coding
2011/9/14
Abstract: A lower bound on the minimum error probability for multihypothesis testing is established. The bound, which is expressed in terms of the cumulative distribution function of the tilted poster...
Non-equilibrium Information Envelopes and the Capacity-Delay-Error-Tradeoff of Source Coding
Non-equilibrium Information Envelopes Capacity-Delay-Error-Tradeoff Source Coding Information Theory
2011/10/8
Abstract: This paper develops an envelope-based approach to establish a link between information and queueing theory. Unlike classical, equilibrium information theory, information envelopes focus on t...
ETS: An Error Tolerable System for Coreference Resolution
ETS An Error Tolerable System Coreference Resolution
2013/4/22
This paper presents our error tolerable sys-tem for coreference resolution in CoNLL-2011(Pradhan et al., 2011) shared task (closed track). Different from most previous reported work, we detect mention...
EXISTENCE OF CONSISTENT ESTIMATES OF LINEAR REGRESSION COEFFICIENTS WHEN THE ERROR VARIANCES ARE UNEQUAL
Linear regression model consistency
2007/12/10
摘要 Consider the linear regression model Y_i=x_i′β+σ_ie_i,i=1,…,n,…, where E(e_i)=0, E(e_ie_j)=δ_(ij), 00. This paper shows that (i) if σ_i~2,i=1,2…, are known, then the necessary and sufficient condit...

2007/8/7
Residual-based a posteriori error estimate for conforming finite element solutions of incompressible Navier-Stokes equations, which is computed with a new two-level method that is different from Volke...
IDENTIFICATION ERROR BOUNDS AND ASYMPTOTIC DISTRIBUTIONS FOR SYSTEMS WITH STRUCTURAL UNCERTAINTIES

2007/8/7
This work is concerned with identification of systems that are subject to notonly measurement noises, but also structural uncertainties such as unmodeleddynamics, sensor nonlinear mismatch, and observ...

Nonparametric semiparametric regression
2007/8/7
Under a locally generalized Gaussian error's structure, we obtain strong uniform consistency for nonparametric regression function estimators and strong consistency for parametric component estimators...
If we restrict the postman to traversing each edge at most twice in the windy postman problem (WPP), we will get a new problem: 2WPP. An approximation algorithmhas been posed by M. Guan for the WPP. I...
