Credence estimation and error prediction in biometric identity verification

This paper focuses on the estimation of credence in the correctness of classification decisions produced by a biometric identity verification system. We adopt the concept of decision credence defined in terms of subjective Bayesian degree of belief. We dem ...

Efficient Use of the Query Optimizer for Automated Database Design

Anastasia Ailamaki, Debabrata Dash

State-of-the-art database design tools rely on the query optimizer for comparing between physical design alternatives. Although it provides an appropriate cost model for physical design, query optimization is a computationally expensive process. The signif ...

Travel Time Estimation on a Signalised Urban Networks using Cumulative Plots

André-Gilles Dumont, Edward Chung, Ashish Bhaskar

This paper presents the development and testing of a methodology for estimation of average travel time on signalised urban networks. The methodology considers the classical analytical procedure, where average travel time on a study link is estimated as the ...

Tomographic approach for parametric estimation of local diffusive sources and application to heat diffusion

Martin Vetterli, Luciano Sbaiz, Ivana Jovanovic

We consider localized instantaneous sources that reside in a 2D dif- fusive environment. Our goal is to reconstruct the induced field from the measurements obtained by distributed sensors. Although the field is non-bandlimited, we capitalize on the fact th ...

A New DOA Estimation Method Using a Circular Microphone Array

Amin Karbasi

This paper proposes a new DOA (direction of arrival) estimation method based on circular microphone array. For an arbitrary number of microphones, it is analytically shown that DOA estimation reduces to an efficient non-linear optimization problem. Simulat ...

A Spatial Sampling Scheme Based on Innovations Diffusion in Sensor Networks

Ali H. Sayed

This paper considers an estimation network of many distributed sensors with a certain correlation structure. Due to limited communication resources, the network selects only a subset of sensor measurements for estimation as long as the resulting fidelity i ...

Méthodes de rééchantillonnage pour l'estimation de variance

Anthony Christopher Davison

Nous passons en revue des techniques de rééchantillonnage utilisées pour l'estimation de variance en sondage. Les techniques de rééchantillonnage considérées sont basées sur la linéarisation, le jackknife, les répétitions équilibrées répétées, et le bootst ...

A DOA Estimation Method For an Arbitrary Triangular Microphone Arrangement

Amin Karbasi

This paper proposes a new DOA (direction of arrival) estimation method for an arbitrary triangular microphone arrangement. Using the phase rotation factors for the crosscorrelations between the adjacent-microphone signals, a general form of the integrated ...
