Önceden eğitilmiş metin üretim modelini değerlendirme

PyBooks ekibi, verdiğin bir isteme göre metin üretmek için senin de denediğin önceden eğitilmiş bir GPT-2 modelini kullandı. Şimdi, üretilen bu metnin kalitesini değerlendirmek istiyorlar. Bunu başarmak için, senden üretilen metni bir başvuru (referans) metni kullanarak değerlendirmeni istediler.

BLEUScore, ROUGEScore senin için yüklendi.

reference_text = "Once upon a time, there was a little girl who lived in a village near the forest."
generated_text = "Once upon a time, the world was a place of great beauty and great danger. The world of the gods was the place where the great gods were born, and where they were to live."

# Initialize BLEU and ROUGE scorers
bleu = ____()
rouge = ____()

# Calculate the BLEU and ROUGE scores
bleu_score = bleu([____], [[reference_text]])
rouge_score = rouge([generated_text], [[____]])

# Print the BLEU and ROUGE scores
