arXiv:2606.16379v1 Announce Type: new Abstract: Evaluating representation similarity is fundamental to representation learning. However, existing metrics suffer from significant limitations: they lack interpretability due to shifting baselines, lack robustness to outliers, and are computationally intractable for large datasets, forcing reliance on heuristic approximations. To address this, we develop an ordinal-similarity framework, instantiated by the Triplet (TSI) and Quadruplet (QSI) Similarity Indices, which measure alignment by quantifying the consistency of ordinal relationships.

The increasing complexity and scale of AI models necessitate more robust and interpretable methods for evaluating representation learning, pushing researchers to develop new frameworks.
Improved representation alignment methods can lead to more reliable, understandable, and scalable AI systems, impacting training efficiency and the trustworthiness of AI deployments.
The ability to accurately and efficiently assess representation similarity without heuristic approximations could accelerate AI research and development, particularly for large datasets.
