Enhancing Video Representations with Spatiotemporal-Semantic Residual to Mitigate Hallucinations in Video Large Multimodal Models
Researchers have developed several new methods to combat hallucinations in video large multimodal models (VLMMs). One approach, MultiToP, refines unreliable visual tokens before language generation by selectively substituting them with a global patch token. Another method, ViSSRes, enhances video representations using a lightweight network to improve spatiotemporal and semantic consistency. A third technique focuses on refining textual embeddings to encourage better integration of visual information and reduce over-reliance on language priors. These methods have shown significant improvements in reducing hallucination rates and enhancing video understanding capabilities across various benchmarks. AI
