Learning What to Remember: Test-Time Training via Context Distillation

Zixuan Wang, Xingyu Dang, Rui-Jie Zhu +4

Effective long-context modeling is not merely about retaining more of the past, but about preserving the information that may prove relevant later. Test-time training (TTT) is an a…

DiscoLoop: Looping Discrete Embeddings and Continuous Hidden States for Multi-hop Reasoning

Hengyu Fu, Tianyu Guo, Zixuan Wang +5

Large language models achieve strong performance on many reasoning tasks when allowed to externalize intermediate steps as Chain-of-Thought (CoT). However, many questions require t…

Plan, Verify and Fill: A Structured Parallel Decoding Approach for Diffusion Language Models

Miao Li, Hanyang Jiang, Sikai Cheng +6

Diffusion Language Models (DLMs) present a promising non-sequential paradigm for text generation, distinct from standard autoregressive (AR) approaches. However, current decoding s…

Two-stage Online Reusable Resource Allocation: Reservation, Overbooking and Confirmation Call

Ruicheng Ao, Hengyu Fu, David Simchi-levi

We study a two-stage online reusable resource allocation problem over T days involving advance reservations and walk-ins. Each day begins with a reservation stage (Stage I), where…

From Bits to Rounds: Parallel Decoding with Exploration for Diffusion Language Models

Hengyu Fu, Baihe Huang, Virginia Adams +3

Diffusion Language Models (DLMs) have recently emerged as a strong alternative to autoregressive language models (LMs). DLMs offer comparable accuracy with faster inference speed v…
