New pretraining strategy relaxes cross-modal correspondence for remote sensing

Researchers have developed a new pretraining strategy called SemPair that relaxes the requirement for exact instance-level correspondence in multimodal remote sensing. This approach uses class-consistent cross-instance pairs instead of strictly paired observations, preserving shared semantic structure while marginalizing instance-specific correlations. Experiments with MixPair, an interpolation between semantic and exact pairing, show that SemPair achieves performance comparable to exact pairing and that the instance-pairing ratio has a non-monotonic relationship with downstream transfer. AI

IMPACT This research suggests a more scalable approach to multimodal pretraining by reducing reliance on costly instance-aligned data.

    Relaxing Cross-Modal Correspondence for Multimodal Remote Sensing Pretraining

    arXiv:2611.13807v1 Announce Type: cross Abstract: Multimodal remote sensing pretraining commonly relies on exact instance-level correspondence across modalities, implicitly treating strictly paired observations as a prerequisite for learning transferable representations. In this …
