Résumé
It and metrics like BLEU and ROUGE are how researchers actually measure whether a model is getting better.

What is Perplexity and Language Metrics?
Perplexity mooy poñ biñ gëna xam ni modelu làkk 'yeemu' ci mbind dëgg — lu gëna ndaw dafay tekki ni dafay gëna wóolu kàddu yi. Moom ak ay metrics yu melni BLEU ak ROUGE ñooy anam wi gëstukat yi di nattee ndax model bi dafay gëna baax.
Lan la poñ yu gëna néew ci jaaxle di wane ci xeetu làkk?
Perplexity measures how surprised a model is by real text; lower perplexity means it assigns higher probability to the actual next words, so it predicts more confidently.

__AIU_PROTECTED_3_ mooy exponentiel bu moyenne log-likelihood bu baaxul, moo tax mu nekk coppite bu jub ci perte entropi croisé bi model bi tàggat ngir wàññi.
Benn model dafay joxe probabilite bu méngoo ci vocabulaire bu 10,000 baat te kenn duko jàng. Luy jaaxleem?
Perplexity is the effective number of equally likely choices. Pure uniform guessing over 10,000 words gives a perplexity of 10,000.
