The 2nuSVM: A CostSensitive Extension of the nuSVM
(20051201)Standard classification algorithms aim to minimize the probability of making an incorrect classification. In many important applications, however, some kinds of errors are more important than others. In this report we ... 
An Adaptive OrthogonalSeries Estimator for Probability Density Functions
(19780220)Given a sample set X1,...,XN of independent identically distributed realvalued random variables, each with the unknown probability density function f(â ¢), the problem considered is to estimate f from the sample set. The ... 
Adaptive Wavelet Transforms via Lifting
(19990115)This paper develops new algorithms for adapted multiscale analysis and signal adaptive wavelet transforms. We construct our adaptive transforms with the <i>lifting scheme</i>, which decomposes the wavelet transform into ... 
An Algorithm for Extraction of More than One Optimal Linear Feature from Several Gaussian Pattern Classes
(19760420)Two algorithms have been developed at Rice University for optimal linear feature extraction based on the minimization risk (probability) of misclassification under the assumption that the class conditional probability ... 
An Algorithm for Optimal Single Linear Feature Extraction from Several Gaussian Pattern Classes
(19751120)A computational algorithm is presented for the extraction of an optimal single linear feature from several Gaussian pattern classes. The algorithm minimizes the increase in the probability of misclassification in the ... 
An Algorithm to Factor Polynomial Matrices
