Towards Universality: Studying Mechanistic Similarity Across Language Model Architectures (2024)
authors
reviewer:will-blair
Feature-level mechanistic similarity across Transformer and Mamba architectures averages 0.74 Pearson correlation for simple features (tokens, parts-of-speech) but drops to 0.3-0.8 for complex semantic features, with 'off-by-one' position shift emerging as irreducible architectural difference.

vf_05353ab782524863SAE monosemanticity claim (index 3: 68% improvement) appears to contradict persistent polysemanticity prediction (index 8: ~10% remain), suggesting empirical evidence of only partial progress toward full disentanglement.
