Robustness of Multimodal RAG Systems

Establish robustness enhancement techniques for multimodal retrieval-augmented generation systems that mitigate modality bias and adversarial perturbations and preserve performance when confronted with low-quality or outdated external sources.

Background

The paper notes that multimodal RAG systems often over-rely on text, struggle with precise source attribution, and are vulnerable to adversarial inputs and degraded sources.

While unimodal RAG trustworthiness has been studied, the robustness of multimodal RAG remains unresolved and is identified as a key research priority.

References

While the trustworthiness of unimodal RAGs has been studied , enhancing the robustness of multimodal RAGs remains an open challenge and a promising research direction.
