New tensor similarity metric aids neural network interpretability

Researchers have developed a new metric called tensor similarity to assess the functional equivalence of computational parts within neural networks. This method is designed to be invariant to certain symmetries, allowing for a more robust comparison of network components than existing behavioral or parameter-based measures. The new metric has demonstrated a higher fidelity in tracking training dynamics like grokking and backdoor insertion, effectively treating the verification of network similarity and faithfulness as an algebraic problem.
