rsa.informativity: RSA informativity

In benpeloquin7/rrrsa: Run Rational Speech Act Models of Pragmatic Inference

Description

Calculate: e^(-alpha * (-log(p(m|u)) - cost))

Usage

rsa.informativity(m_u, alpha = 1, cost = 0)

Arguments

m_u,	literal semantics of meaning given utterance
alpha,	decision noise parameter (speaker's deviation from optimal action selection)
cost,	cost of utterance u

Value

Informativity of utterance u given meaning m and cost

Examples

rsa.informativity(m_u = 0.5, alpha = 1, cost = 0) == 0.5
rsa.informativity(m_u = 0, alpha = 1, cost = 0) == 0.0
rsa.informativity(m_u = 0.5, alpha = 1, cost = 2)
