Measuring the Measures: Discriminative Capacity of Representational Similarity Metrics Across Model Families

arXiv — cs.LGWednesday, December 10, 2025 at 5:00:00 AM
  • A new study has introduced a quantitative framework to evaluate representational similarity metrics, assessing their discriminative capacity across various model families, including CNNs, Vision Transformers, and ConvNeXt. The research utilizes three separability measures to compare commonly used metrics such as RSA and soft matching, revealing that stricter alignment constraints enhance separability.
  • This development is significant as it provides a systematic approach to understanding the effectiveness of different representational similarity metrics in distinguishing between model families. The findings could influence future research and applications in both neuroscience and artificial intelligence.
  • The study contributes to ongoing discussions about the performance of various neural network architectures, particularly Vision Transformers, which have been noted for their unique inductive bottlenecks. This research aligns with broader efforts to refine model evaluation methods and enhance the robustness of AI systems, addressing challenges such as representational sparsity and adversarial vulnerabilities.
