BLEU and ROUGE metrics explained for language model evaluation

BLEU and ROUGE are key metrics used to evaluate the performance of language models, particularly in tasks like machine translation and text summarization. BLEU focuses on precision of n-grams and includes a penalty for brevity, while ROUGE emphasizes recall and uses an F-measure. These quantitative measures allow developers to compare models and identify areas for improvement in generating coherent and relevant text. AI
