ClockRoPE: Random Fourier Rotations for Temporal Routine Modeling

Yiwen Chen, Joshua Ainslie, Krzysztof Choromanski +4

Rotary Position Embedding (RoPE) has been widely adopted in transformer-based large language models. However, its log-linear frequency schedule, originally designed to produce long…

Route Before Retrieve: Activating Latent Routing Abilities of LLMs for RAG vs. Long-Context Selection

Yiwen Chen, Kuan Li, Fuzhen Zhuang +6

Recent advances in large language models (LLMs) have expanded the context window to beyond 128K tokens, enabling long-document understanding and multi-source reasoning. A key chall…
