erroristotle/dvdr_llmАнсамблевый фреймворк для обнаружения и исправления уязвимостей программного обеспечения с использованием нескольких больших языковых моделей, с анализом консенсуса и инструментами оценки для компромиссов между точностью и полнотой.
Официальная реализация и артефакт для исследовательской статьи:
"DVDR-LLM: Когда LLM работают лучше вместе для обнаружения и исправления уязвимостей ПО?"
DVDR-LLM — это ансамблевый фреймворк, который систематически исследует фундаментальные компромиссы при агрегации нескольких больших языковых моделей (LLM) для обнаружения и исправления уязвимостей ПО. Наша всесторонняя оценка выявляет критические выводы о балансировании точности и полноты, преимуществах разнообразия моделей и подходах, основанных на консенсусе, в критически важных для безопасности приложениях.
