Fast identification of highly distorted images
In this paper, we consider a low complexity identification system for highly distorted images. The performance of the proposed identification system is analyzed based on the avera...

Fast fully polynomial approximation schemes for minimizing completion time variance
Abstract. We present fully polynomial approximation schemes for the problem of minimizing completion time variance of a set of n jobs on a single machine. The fastest of these sche...

The use of subvector quantization and discrete densities for fast GMM computation for speaker verification
Last year, we showed that the computation of a GMM-UBMbased speaker verification (SV) system may be sped up by 30 times by using a high-density discrete model (HDDM) on the NIST 2...

Solving a Structured Quadratic Eigenvalue Problem by a Structure-Preserving Doubling Algorithm
Abstract. In studying the vibration of fast trains, we encounter a palindromic quadratic eigenvalue problem (QEP) (2AT +Q+A)z = 0, where A, Q Cn

Fast robust estimation of prediction error based on resampling
Robust estimators of the prediction error of a linear model are proposed. The estimators are based on the resampling techniques cross-validation and bootstrap. The robustness of t...
