Overview

Model Description: roberta-large-faithcritic is the RoBERTa large model fine-tuned on FaithCritic, a derivative of the FaithDial dataset. The objective is to predict whether an utterance is faithful or not, given the source knowledge.

The hyperparameters are provided in hparams.yml. To know more about how to train a critic model, visit our repo.

Usage

from transformers import AutoTokenizer, AutoModel

tokenizer = AutoTokenizer.from_pretrained("McGill-NLP/roberta-large-faithcritic")
model = AutoModel.from_pretrained("McGill-NLP/roberta-large-faithcritic")

knowledge = "A cardigan is a type of knitted garment (sweater) that has an open front."
response = "The old version is the regular one, knitted garment that has open front and buttons!"
input = tokenizer(knowledge, response)
output = model(**input)
