Analysis of the copula correlation matrix for meta-elliptical distributions
Yue Zhao
Video in druga učna gradiva
Oznake: computer science;machine learning
We study the copula correlation matrix $\Sigma$ for elliptical copulas. In this context, the correlations are connected to Kendall's tau through a sine function transformation. Hence, a natural estimate for $\Sigma$ is the plug-in estimator $\widehat\Sigma$ with Kendall's tau statistics. In this ta ...

Oznake: artificial bee colony;chaos-decision variable;harmonic distortion;harmonic estimation;harmonic suppression;
This paper presents a new hybrid algorithm based on artificial bee colony (ABC) and chaotic search strategy (CSS), known as ABC-CSS to solve the harmonic estimation problems in the case of time varying acceleration response signal. The ABC algorithm simulates the intelligent behavior of bees in natu ...
