WebApr 28, 2024 · The following picture shows the loss and perplexity during fine-tuning GPT-2. The lower loss means that the generated words are closer to the original labels I provided, while the lower perplexity means that the model is able to generate high probability words. For example, if the probability is one, then the perplexity will be one meaning that ... WebThis paper presents an investigation aimed at studying how the linguistic structure of a sentence affects the perplexity of two of the most popular Neural Language Models (NLMs), BERT and GPT-2. We first compare the sentence-level likelihood computed with BERT and the GPT-2’s perplexity showing that the two metrics are correlated.
