Activation Verbalizers Struggle to Reveal Model's Internal Reasoning in Math Tasks

Researchers evaluated activation verbalizers, natural‑language autoencoders that map hidden activations to text, to see if they can surface a model’s chain‑of‑thought while solving math problems. Tests on open‑weight NLAs for Qwen2.5, Gemma, and Llama showed occasional hints of reasoning but overall unreliable reconstruction, limiting their interpretability value.

Transformer Activations Form Metastable Token Clusters, Study Finds

Researchers experimentally verify that trained transformer models exhibit metastable token clustering predicted by an idealized attention theory, though the proposed energy dynamics and collapse speed predictions are falsified. The clustering depends on the value matrix rather than model size, highlighting nuanced mechanisms of attention dynamics.
