• Abstract: The ability to extract compact, meaningful summaries from large-scale and multimodal data is critical for numerous applications, ranging from video analytics to medical reports. Prior methods in cross-modal summarization have often suffered from high computational overheads and limited interpretability. In this paper, we propose a \textit{Cross-Modal State-Space Graph Reasoning} (\textbf{CSS-GR}) framework that incorporates a state-space model with graph-based message passing, inspired by prior work on efficient state-space models. Unlike existing approaches relying on purely sequential models, our method constructs a graph that captures inter- and intra-modal relationships, allowing more holistic reasoning over both textual and visual streams. We demonstrate that our approach significantly improves summarization quality and interpretability while maintaining computational efficiency, as validated on standard multimodal summarization benchmarks. We also provide a thorough ablation study to highlight the contributions of each component.

  This paper introduces End-to-End Visual Chain-of-Thought (V-CoT) for chart summarization. Our method directly trains an LVLM to process chart images and generate textual summaries in an end-to-end fashion. We incorporate a visual Chain-of-Thought mechanism through instruction fine-tuning, implicitly guiding the LVLM to perform visual reasoning steps.

  Long-range interactions are essential for the correct description of complex systems in many scientific fields. Most deep graph networks cannot really model long-range dependencies due to intrinsic limitations of (synchronous) message passing. This work proposes a general framework that learns to mitigate these limitations.
