UnverifiedBLEU is insensitive to synonym substitution and word order variation, and its correlation with human judgment is particularly weak for morphologically rich languages.69% similarVerifiedText generated by large language models tends to have low perplexity, with word choices that are overly consistent with probabilistic expectations, lacking the unexpectedness of human writing.68% similarUnverifiedPerplexity depends heavily on the tokenizer: different tokenizers split text into different token granularities, so the same passage yields different token counts, and perplexity values cannot be compared directly.68% similarUnverifiedThe same model may produce completely different answers when faced with semantically similar but differently worded questions.68% similarUnverifiedThe implicit assumption of BPE-type methods is that high-frequency segments are more worthy of entering the vocabulary, which causes vocabulary capacity in multilingual scenarios to naturally tilt toward high-resource languages.67% similar
