arXiv:2606.30625v1 Announce Type: cross Abstract: Contrastive embedding models trained with scale-invariant losses are typically paired with distance metrics like cosine similarity, effectively ignoring embedding magnitudes. However, surprisingly, empirical studies reveal that despite this, these "discarded" norms seem to correlate with semantic properties such as concept specificity, token frequency, and human uncertainty. In this work, we provide a formal theoretical framework explaining this phenomenon. By analyzing the optimization dynamics, we derive an analytic formula demonstrating that
The paper provides a formal theoretical framework to explain an observed empirical phenomenon in contrastive embedding models, advancing the fundamental understanding of AI systems.
Understanding the semantic specificity imprinted in embedding norms can lead to more robust, interpretable, and potentially more efficient AI models, influencing future AI development and applications.
This theoretical breakthrough moves us beyond empirical observation to a foundational understanding of how contrastive learning encodes semantic information, potentially opening new avenues for model design.
