Information Gain This functions runs Information Gain for two features, returning the score

Description

Information Gain This functions runs Information Gain for two features, returning the score

Usage

get_IG_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 Information Gain 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_IG_for_vector_pair(discrete_expression_gene_1,discrete_expression_gene_2)
