Image Tokens Matter: Mitigating Hallucination in Discrete Tokenizer-based Large Vision-Language Models via Latent Editing

Weixing Wang, Zifeng Ding, Jindong Gu +4

Large Vision-Language Models (LVLMs) with discrete image tokenizers unify multimodal representations by encoding visual inputs into a finite set of tokens. Despite their effectiven…

Feature Distribution Shift Mitigation with Contrastive Pretraining for Intrusion Detection

Weixing Wang, Haojin Yang, Christoph Meinel +3

In recent years, there has been a growing interest in using Machine Learning (ML), especially Deep Learning (DL) to solve Network Intrusion Detection (NID) problems. However, the f…
