This paper focuses on statistical independence of multiple variables from the viewpoint of linear algebra. While information granules of statistical independence of two variables can be viewed as determinants of 2 times 2- submatrices, those of three variables consist of several combination s of determinants. However, this combination can be viewed as a linear sum over the all combinarial pairs of...
In this paper we introduce the problem of predicting the mutagenic toxicity property of chemical compounds and we discuss how this can be partially formulated as a computational intelligence problem. Then we develop a statistical model based on a selected set of descriptors of the molecular structure. The classifier, that we derived from SVM methods, outperforms the available methods in performance...
In 2008, an American presidential election was held. In this study, we examined the speeches of three candidates to educe their linguistic features statistically. In short, frequency characteristics of character-appearance and word-appearance were investigated. These characteristics were approximated by an exponential function. Furthermore, the percentage of required vocabulary and that of basic vocabulary...
This paper represents the results of investigation establishing a connection of socio-economic factors and adolescents' health in Georgia. Health indicators are extracted from the special anonymous survey on adolescents in Georgia. The socio-economic factors are evaluated by independent experts. Methods based on elements of statistical analysis as well as on similarity relations from fuzzy set theory...
We discuss the historical perspective of concepts of fuzziness and randomness, with emphasis on fuzzy random variables. We will describe the analysis of the interpretation, modeling, and impact of fuzzy random variables. Examples will be given of scenarios modeled by fuzzy random variables. Also, main approaches using fuzzy random variables will be discussed. The theoretical concept of expected value...
