What Is Bleu Score Used for with Language Models?
Bleu Score
BLEU is a precision-focused metric that measures the n-gram overlap between the generated text and the reference text. The score also considers a brevity penalty where a penalty is applied when the machine-generated text is too short compared to reference text. It is a metric that is generally used for machine translation performance. The score ranges from 0 to 1, with higher scores indicating greater similarity between the generated text and the reference text.
