🔥 News

• This paper has been accepted by CVPR 2024!
• This is the official repository for the paper "HalluciDoctor: Mitigating Hallucinatory Toxicity in Visual Instruction Data". 🍇 [Read our arXiv Paper].
• We update the main code of HalluciDoctor and corresponding datasets LLaVA+ and LLaVA++.
• Release LLaVA+ and LLaVA++ models for MiniGPT4 with vicuna-7b.

⭐ Steps

• Dataset preparation: LLaVA-158K; coco_category.json; coco_object_co_occur.json; object_sample for 'counterfactual images' following INSTALL.md.
• HalluciDoctor Framework
