In lubianat/FCBF: Fast Correlation Based Filter for Feature Selection

Description

get_SU_for_vector_pair Formula for symetrical uncertainty as described in Yu, L. and Liu, H. , 2003. This functions runs symmetrical uncertainty for two features, returning the score

Usage

get_SU_for_vector_pair(x, y, base = 2)

Arguments

x	A vector containing a categorical feature
y	A vector containing other categorical feature
base	The base used for the logaritmic function. The default is exp(1) (~2.718)

Value

A numerical value for the Symetrical Uncertainty score

Examples

 data(scDengue)
 exprs <- SummarizedExperiment::assay(scDengue, 'logcounts')
 discrete_expression <- as.data.frame(discretize_exprs(exprs))
 discrete_expression_gene_1 <- discrete_expression$V1
 discrete_expression_gene_2 <- discrete_expression$V2
 get_SU_for_vector_pair(discrete_expression_gene_1,discrete_expression_gene_2)
