Transformers Collapse to Low-Dim Manifolds

Transformers Collapse to Low-Dim Manifolds

Transformer training on modular arithmetic tasks collapses high-dimensional parameters to 3-4D execution manifolds. This structure explains attention concentration, SGD integrability, and sparse autoencoder limits. Core computation occurs in reduced subspaces amid overparameterization.

Tokens Enable Emergent Resource Rationality

Tokens Enable Emergent Resource Rationality

Inference-time scaling in language models leads to adaptive resource rationality without explicit cost rewards. Models shift from brute-force to analytic strategies as task complexity rises. LRMs show robustness on challenging functions like XOR/XNOR unlike IT models.
