échantillonnage basée sur entropie
Entropy-based sampling dafay méngale ni LLM di tànnee token bi ci topp, lépp di aju ci ni model bi wóorul ci saa si.
Résumé
When the model is confident the strategy stays decisive; when entropy is high it adjusts to avoid incoherence or to signal that the model is unsure.

Entropy-based sampling dafay méngale ni LLM di tànnee token bi ci topp, lépp di aju ci ni model bi wóorul ci saa si. Sudee model bi wóolu na boppam, pexe bi dafay des ci dogal; Su entropi bi yéegee dafay aju ngir moytu incoherence wala ngir wane ni model bi wóorul.
