Gpt 2 perplexity

WebThe perplexity of a sequence of words W is calculated with the joint probabilities P of each word w using the formula: Perplexity(W) = P(w 1;w 2::w N) 1=N We use the implementation of GPT-2 available from HuggingFace (Wolf et al., 2024). Since GPT-2 is trained on written text and we experiment with spoken language, we fine-tune our GPT-2 model ... WebJun 7, 2024 · OpenAI’s GPT-2, mentioned above, achieves about 1 bit per character on (yet another) Wikipedia dataset. Keeping in mind that there are about 5 characters per word in written English, this corresponds to about 5 bits, or a perplexity of 2⁵=32. Note this is substantially higher than the perplexities discussed as state-of-the-art benchmarks!
