Others seek to protect public discourse from malicious uses of text generators that could undermine democracies. We used the first few words of each human text to serve as our prompts: For each of these six prompts, we generated ten texts using each of the following five methods: We selected our temperature value (= 0.7) based on common practice. Likewise we can say with 95% confidence that outputs prompted by the Bible, regardless of generation method, are significantly more similar to each other. By definition the perplexity (triple P) is: PP (p) = e^ (H (p)) Where H stands for chaos (Ancient Greek: ) or entropy. Its exciting that this level of cheap specialization is possible, and this opens the doors for lots of new problem domains to start taking advantage of a state-of-the-art language model. We see that our six samples of human text (red) offer a wide range of perplexity. No -> since you don't take into account the probability p(first_token_sentence_2 | last_token_sentence_1), but it will be a very good approximation. The Curious Case of Natural Text Degeneration. We find that outputs from the Top-P method have significantly higher perplexity than outputs produced from the Beam Search, Temperature or Top-K We see no significant differences between Top-P, Top-K, Sampling, or the human generated texts. Here also, we are willing to provide you with the support that you need. We also find that Top-P generates output with significantly less perplexity than Sampling, and significantly more perplexity than all other non-human methods.
