When structure matching is strict (λ = 1), only trained BERT and Infersent capture syntactic information according to RSA; however, RSA REGRESS still shows moderate correlation for BoW and the untrained versions of BERT and Infersent.
rSA rEGrESS is less sensitive to the value of λ than rSA since changing it from 1 2 to 1 does not alter results in a qualitative sense.
