Dual-branch Prompting for Multimodal Machine Translation

arXiv:2507.17588v3 Announce Type: replace-cross Abstract: Multimodal Machine Translation (MMT) typically enhances text-only translation by incorporating aligned visual features. Despite the remarkable progress, state-of-the-art MMT approaches often rely on paired image-text inputs at inference and are sensitive to irrelevant visual noise, which limits their robustness and practical applicability. To address these issues, we propose D2P-MMT, a diffusion-based dual-branch prompting framework for robust vision-guided translation. Specifically, D2P-MMT requires only the source text and a reconstru

Why this matters
Why now

The development of more robust multimodal machine translation is crucial as AI models become increasingly sophisticated and pervasive in real-world applications requiring nuanced sensory input.

Why it’s important

This signifies a step towards more practical and resilient AI systems, reducing their sensitivity to imperfect visual data and expanding their applicability in diverse environments.

What changes

The reliance of multimodal machine translation on perfectly aligned and noise-free visual inputs is reduced, allowing for broader deployment and improved performance in complex scenarios.
