Full-bandwidth transformer

Xi Wang, Ziyang Cai, Zheng Zhan +5

Autoregressive transformers compute along two axes: horizontally across generated tokens, and vertically through model depth. Dense attention gives each token broad horizontal acce…

T^2MLR: Transformer with Temporal Middle-Layer Recurrence

Ziyang Cai, Xingyu Zhu, Yihe Dong +2

The paper proposes T²MLR, a transformer variant that injects a cached middle‑layer representation from the previous token into an earlier layer of the current token, allowing inter…

Goedel-Architect: Streamlining Formal Theorem Proving with Blueprint Generation and Refinement

Jui-Hui Chung, Ziyang Cai, Zihao Li +14

We introduce Goedel-Architect, an agentic framework for formal theorem proving in Lean 4 centered on blueprint generation and refinement. A blueprint is a dependency graph of defin…

ML-AutoResearch: Training Machine Learning Research Agents with Automatically Generated Environments

Ziyang Cai, Amir Saeidi, Harkirat Behl

With the advent of AI agents, automated scientific discovery is becoming an increasingly plausible goal. However, training agents to autonomously execute the engineering-heavy labo…

h1: Bootstrapping LLMs to Reason over Longer Horizons via Reinforcement Learning

Sumeet Ramesh Motwani, Alesia Ivanova, Ziyang Cai +5

Large language models excel at short-horizon reasoning tasks, but performance drops as reasoning horizon lengths increase. Existing approaches to combat this rely on inference-time…

Extrapolation by Association: Length Generalization Transfer in Transformers

Ziyang Cai, Nayoung Lee, Avi Schwarzschild +2

Transformer language models have demonstrated impressive generalization capabilities in natural language domains, yet we lack a fine-grained understanding of how such generalizatio…
