Cost function for one parameter optimization for the utterance choice experiments. (iterative setting) Optimizing non-obedience. Softness and klValueFactor are fixed. — SimpleRSAModelUttKLDivParamB

Simple RSA

Non-obedience is optimized.

Softness is fixed at 0. klValueFactor is fixed at 1.

SimpleRSAModelUttKLDivParamB_iterative(par, data)

Arguments

par

par	One value vector, which specifies one of three parameters to be optimized: non-obedience, This parameter determines the extent to which the instruction of the speaker is obeyed by the listener.(0 = full obedience, infinity = full instruction ignorance).Example:0: Listener always picks red objects following the utterance "red".infinity: Listener as likely to pick green, blue or red objects even if the utterance is "red".
data	A matrix with data rows. column structure: `[1:OC1,OC2,OC3,4:numUttOptions,6: picked utterance]` 1:OC1 Object 1. A value between 1 and 27. 2:OC2 Object 2. A value between 1 and 27. 3:OC3 Object 3. A value between 1 and 27. 4:numUttOptions The number of valid utterances in the scene. 6: picked utterance The utterance picked by the participant.
