RSAModelLL2_n2: Cost function for two parameter optimization. Optimizing...

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

Description

Full-RSA

2 parameter optimization; The softness and alpha parameters are optimized.

The non-obedience parameter is fixed.

Usage

RSAModelLL2_n2(params, data)

Arguments

params

Two value vector, which specifies two of three parameters (n1 = not the first, n2 = not the second, n3 = not the third) to be optimized: softPrefValue parameter is optimized, i.e. The strength of "preferring one entity over others". (The larger the value the higher the tendency towards uniform liking) non-obedience parameter is fixed at 0, i.e. The extent to which the instruction of the speaker is obeyed by the listener. (0 = full obedience, infinity = full instruction ignorance). alpha parameter is optimized, i.e. An exponential scaling of the speaker choosing the utterance that maximizes the chance of the listener getting the target object right.

data

A matrix with data rows. column structure: [1:OC1,OC2,OC3,4:UUFeat, 5:Q1Feat,6:Q2Feat] [7:Q1AnswerV1,V2,V3, 10:Q2AnswerV1,V2,V3] 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:UUFeat Uttered feature. A number between 1 and 3. (1: shape, 2: pattern, 3: color) 5:Q1Feat Questioned feature 1. A number between 1 and 3. (1: shape, 2: pattern, 3: color). Example: If you utter "blue" (feature: color), then you can learn something about shape and texture preferences. 6:Q2Feat Questioned feature 2. A number between 1 and 3. (1: shape, 2: pattern, 3: color). Example: If you utter "blue" (feature: color), then you can learn something about shape and texture preferences. 7:Q1AnswerV1, V2, V3 The columns 7-9 contain the participants' slider values for the first questioned feature. 10:Q2AnswerV1, V2, C3 The columns 10-12 contain the participants' slider values for the second questioned feature.
