Finding the principal points of a random variable [Article]
(EDP Sciences, 2001)
The p-principal points of a random variable X with finite second moment are those p points in R minimizing the expected squared distance from X to the closest point. Although the determination of principal points involves ...
Multi-group support vector machines with measurement costs a biobjective approach [Article]
Support Vector Machine has shown to have good performance in many practical classification settings. In this paper we propose, for multi-group classification, a biobjective optimization model in which we consider not only ...
A biobjective method for sample allocation in stratified sampling [Article]
The two main and contradicting criteria guiding sampling design are accuracy of estimators and sampling costs. In stratified random sampling, the sample size must be allocated to strata in order to optimize both objectives. ...
