Vector Linking via Cross-Model Local Isometric Consistency

arXiv:2605.31100v1 Announce Type: new Abstract: We study Vector Linking: given two embedding clouds produced by different black-box encoders over partially overlapping datasets, recover cross-model object correspondences using only vectors. Empirically and theoretically, we show that independently trained contrastive encoders exhibit local geometric consistency: short-range distances are approximately preserved up to a scale factor, while long-range distances are not due to model-specific distortion. Building on this, we propose an iterative, reference-based geometric embedding hashing that re

Why this matters
Why now

The proliferation of various foundational models and embedding techniques necessitates robust methods for interoperability and data integration without direct data sharing.

Why it’s important

A strategic reader should care as this advancement offers a robust new method for connecting disparate data silos and models, enhancing data utility across different AI systems and organizations.

What changes

The ability to link vector embeddings from different models using geometric consistency allows for deeper cross-platform intelligence and potentially enables new forms of collaborative AI without centralizing raw data.

Winners
