Description of changes:
This PR implements the following changes to
GeneralSemanticRobustnesseval:Word Error Ratemetric that measures syntactic differences, we add theBERTScore Dissimilaritymetric that measures semantic differences. We useBERTScore Dissimilarity = 1 - BERTScore(a dissimilarity metric) instead ofBERTScore(a similarity metric). We use dissimilarity to be consistent withWord Error Rateand the rest ofSemanticRobustnessevals that measure dissimilarities.BERTScore DissimilarityandWord Error Ratewhen the model is non-deterministic.
