Hello, I want to use the modified code to test the text generation task, because I haven't read the paper, I want to ask two questions, first, is the higher the bartscore the better, and second, what does the negative bartscore mean?

Hi, To your questions: (1) The higher score corresponds to a better generation (2) The negative score is the average log-likelihood of each generated token.
