MeSH: Memory-as-State-Highways for Recursive Transformers
Memory-as-State-Highways externalizes state management of recursive transformers into an explicit memory buffer with lightweight routers, addressing undifferentiated computation across iterations and overload of a single hidden state.
Inside the method
[ Recursive core ] × r ↔ memory buffer (read / write routers)
Simplified conceptual schematic. Consult the paper for the complete architecture.
- Recurrence family
- Core recurrence
- Depth control
- Fixed iterations
- KV / state strategy
- Explicit memory buffer across iterations
Reading note
On Pythia 160M–6.9B it beats recursive baselines and, at 1.4B, outperforms the larger non-recursive model by 1.06 points with 33% fewer non-embedding parameters.
