Description
Compute the base-b Shannon cross entropy between a true distribution
p and an unnatural distribution q.
Usage
1
shannon_cross_entropy(p, q, b = 2)
Arguments
p
Dist specifying the true distribution.
q
Dist specifying the unnatural distribution.
b
Numeric giving the base of the logarithm.
Value
Numeric giving the Shannon cross entropy.
Examples
1

p <- Dist(c(1, 0, 0))
q <- Dist(c(2, 1, 1))
shannon_cross_entropy(p, q) # 1.0000000
shannon_cross_entropy(q, p) # Inf
shannon_cross_entropy(p, q, b = 3) # 0.6309298
shannon_cross_entropy(q, p, b = 3) # Inf
