Return the Shannon entropy of a string column. If the string is empty, the entropy is 0.

h2o.entropy(x)

Arguments

x

The column on which to calculate the entropy.

Examples

# NOT RUN {
library(h2o)
h2o.init()
buys <- as.h2o(c("no", "no", "yes", "yes", "yes", "no", "yes", "no", "yes", "yes","no"))
buys_entropy <- h2o.entropy(buys)
# }
