SimpleRSAModelUttKLDivParamBK_iterative: Cost function for two parameter optimization for the...

In haniaelkersh/rsa-publish-test: Prior Inference Package

Description

Simple RSA

Non-obedience and klValueFactor are optimized.

Softness is fixed at 0.

Usage

SimpleRSAModelUttKLDivParamBK_iterative(params, data)

Arguments

params

Two value vector specifying the two 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". klValueFactor can be negative, zero or positive: zero Don't care about learning about feature preferences of the listener positive Care about learning about feature preferences of the listener negative Trying to pick non-ambiguous utterances

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.

Details

This is the iterative version of SimpleRSAModelUttKLDivParamBK

This function uses SimpleRSAModelUttKLDiv_3params_iterative.

Value

Minimized Kullback-Leibler divergence and the optimal parameters.
