Introduction

We propose HA-DPO (Hallucination-aware Direct Preference Optimization), which eliminates LVLM hallucination using GPT-4 generated positive-negative data based on DPO (Direct Preference Optimization).

This repo provides:

High-quality positive-negative hallucination-aware data
DPO framework for multiple LVLM (based on TRL)
- MiniGPT-4
- LLaVA-1.5
- InstructBLIP
SHR Evaluation (Sentence-level Hallucination Ratio)
Human-free positive-negative data mining pipeline

Demo

Online demo will be available soon!

Acknowledgement

MiniGPT-4. The MiniGPT-4 part of HA-DPO is based on the official MiniGPT-4 implementation.
VIGC. The InstructBLIP part of HA-DPO is built on VIGC, which is an amazing visual instruction generation and correction method.
LLaVA-1.5. The LLaVA-v1.5 part of HA-DPO is based on the official LLaVA-1.5 implementation, which is a great open-source work on LVLM.
TRL. Most model training and optimizing codes of HA-DPO are stemed from TRL, which is a great human-preference learning framework on LLM.
