  1. ConSERT: A Contrastive Framework for Self-Supervised Sentence Representation Transfer (2021 · 647 citations)
    Sentence vectors taken directly from BERT, whether the [CLS] output or averaged token embeddings, behave poorly on semantic textual similarity (STS).
  2. DualRAG: A Dual-Process Approach to Integrate Reasoning and Retrieval for Multi-Hop Question Answering (2025 · 20 citations)
    Multi-hop question answering requires a model to chain several reasoning steps, and the facts it needs change as the reasoning unfolds.
  3. What Makes a Good Reasoning Chain? Uncovering Structural Patterns in Long Chain-of-Thought Reasoning (2025 · 11 citations)
    Long chain-of-thought (LCoT) reasoning lets LLMs solve hard problems, but it is unclear which properties of a reasoning trace indicate that the final answer will be right.
  4. CE-GPPO: Coordinating Entropy via Gradient-Preserving Clipping Policy Optimization in Reinforcement Learning (2026 · 7 citations)
    The paper tackles unstable policy entropy when large language models are trained with RL for reasoning. PPO-style methods, including GRPO and DAPO, clip the importance sampling ratio, and this silently drops gradients from low-probability tokens. The authors split tokens by advantage sign and probability. They argue…
