Evaluating and Enhancing Negation Comprehension in Remote Sensing MLLMs

arXiv:2606.20177v1 Announce Type: cross Abstract: Multimodal Large Language Models (MLLMs) have demonstrated remarkable success in various Remote Sensing (RS) tasks. However, their ability to comprehend negation remains underexplored, limiting deployment in real-world applications where models must explicitly identify what is false or absent, e.g., emergency responders need to locate non-flooded routes for evacuation. To comprehensively study this limitation, we introduce RS-Neg, the first benchmark to evaluate negation understanding across region-level to scene-level tasks. Specifically, we d

Why this matters
Why now

The rapid advancement and deployment of MLLMs in various domains necessitate a deeper understanding of their limitations, especially in safety-critical applications like remote sensing.

Why it’s important

Improving negation comprehension in MLLMs is crucial for their reliable performance in practical, real-world applications where identifying what is absent or false is as important as identifying what is present.

What changes

The introduction of a dedicated benchmark like RS-Neg will accelerate research and development in making MLLMs more robust and trustworthy for remote sensing tasks requiring nuanced understanding.

Winners
  • · AI researchers
  • · Remote sensing industry
  • · Emergency services
  • · AI developers
Losers
  • · Developers of MLLMs without robust negation handling
  • · Applications requiring high-precision 'absence' detection
Second-order effects
Direct

Remote Sensing MLLMs will become more reliable in critical applications by better understanding negative statements.

Second

This improved reliability will enable broader adoption of MLLMs in sectors like disaster response, environmental monitoring, and defense.

Third

The enhanced capability for precise interpretation will likely lead to MLLMs being integrated into more autonomous decision-making systems where false negatives or positives have high costs.
