Weights-Rotated Preference Optimization for Large Language Models

EMNLP 2025

Despite the efficacy of Direct Preference Optimization (DPO) in aligning Large Language Models (LLMs), reward hacking remains a pivotal challenge. This issue emerges when LLMs excessively reduce the probability of rejected completions to achieve high rewards, without genuinely meeting their intended

ERNIE-Layout: Layout Knowledge Enhanced Pre-training for Visually-rich Document Understanding

EMNLP 2022finding

Recent years have witnessed the rise and success of pre-training techniques in visually-rich document understanding. However, most existing methods lack the systematic mining and utilization of layout-centered knowledge, leading to sub-optimal performances. In this paper, we propose ERNIE-Layout, a…

ERNIE-ViL: Knowledge Enhanced Vision-Language Representations through Scene Graphs

AAAI 2021technical

We propose a knowledge-enhanced approach, ERNIE-ViL, which incorporates structured knowledge obtained from scene graphs to learn joint representations of vision-language. ERNIE-ViL tries to build the detailed semantic connections (objects, attributes of objects and relationships between objects) acr…
