DPO debiasat de stil: actualizarea cunoștințelor LLM cu date de preferințe sintetice care țin cont de fapte

Cercetătorii propun optimizarea preferințelor directe debiasate de stil (SD-DPO) pentru a îmbunătăți acuratețea modelelor de limbaj mari (LLM) în recuperarea cunoștințelor stocate.

Model de limbă mare (LLM)
Un model de limbaj instruit pe corpuri de text masive pentru a genera și analiza text.
Factualitatea
Cât de precis se potrivesc afirmațiile unui model cu informațiile verificabile din lumea reală.

Ce sa întâmplat

Researchers proposed style-debiased direct preference optimization (SD-DPO) to improve the accuracy of large language models (LLMs) in retrieving stored knowledge. They tested SD-DPO on top of EntiGraph, a representative storing-side method that runs continued pretraining (CPT) on text synthesized from the corpus. The results showed that SD-DPO exceeds a baseline CPT on EntiGraph's synthetic data from the same base model and evaluates with the same procedure.
