融合响应特征差异的多模态AI虚假信息检测
Multimodal AI Disinformation Detection Based on Differences in Response Features
摘要
Abstract
[Research purpose]Criminals use AI to generate false graphical information,disrupt public perception,and threaten social stability.The existing detection methods are lack generality in the face of information generated by different AI models,and it is difficult to accurately identify false content.In order to solve this challenge,this study explores an effective detection mechanism based on the differences in response features of generative AI to improve the accuracy and robustness of disinformation detection.[Research method]Through the comparative analysis of the text features of GPT,PaLM2,Llama2,Mixtral and RWKV,the multi-dimensional difference features such as lexical parts of speech,emotional tendencies,grammatical structure,and confusion were extracted,and the BVT-CNN multimodal disinformation detection model fused with BERT and Vision-Transformer was introduced.The ablation comparison method was used to evaluate the influence of differential features on the detection performance.[Research result/conclusion]The results show that the wF1 index increased by 4.94％after the fusion of differential features,which significantly enhances the detection ability of hybrid generative AI information.The research results not only optimize the AI disinformation detection strategy,but also summarize and analyze the differences in response features of various generative models.关键词
