1. **[TORQUE: A Reading Comprehension Dataset of Temporal Ordering Questions](https://md.research.elamur.ai/free/en/papers/ning-2020-torque-reading-comprehension-dataset-temporal/)** *(2020 · 152 citations)* TORQUE asks temporal relations as reading-comprehension questions instead of labelling event pairs with Allen-style relations.
2. **[In Prospect and Retrospect: Reflective Memory Management for Long-term Personalized Dialogue Agents](https://md.research.elamur.ai/free/en/papers/tan-2025-prospect-retrospect-reflective-memory-management/)** *(2025 · 46 citations)* LLM dialogue agents keep no state between sessions, so long-term personalization depends on external memory.
3. **[Speculative Knowledge Distillation: Bridging the Teacher-Student Gap Through Interleaved Sampling](https://md.research.elamur.ai/free/en/papers/xu-2024-speculative-knowledge-distillation-bridging-teacher/)** *(2024 · 41 citations)* Distilling a large language model into a smaller one runs into two failure modes. Supervised KD trains on a fixed set of outputs, so it never sees the kind of text the student produces at inference time. On-policy KD trains on the student's own generations, but early on these are often poor and unfamiliar to the…
4. **[COMPASS: Enhancing Agent Long-Horizon Reasoning with Evolving Context](https://md.research.elamur.ai/free/en/papers/wan-2026-compass-enhancing-agent-long-horizon/)** *(2026 · 1 citation)* LLM agents often fail on long-horizon tasks that need many chained tool calls. Small mistakes pile up, and as the history grows the agent misses key evidence, gets distracted, or stops too early instead of changing its plan. The authors argue that context management is the main obstacle. They propose COMPASS, a…
