Papers The most cited first (OpenAlex and our library). 1. **[A Survey on Hallucination in Large Language Models: Principles, Taxonomy, Challenges, and Open Questions](https://md.research.elamur.ai/free/en/papers/huang-2023-survey-hallucination-large-language-models/)** *(2023 · 3,231 citations)* Large language models often produce fluent, convincing text that is not supported by facts or by the input they were given. 2. **[Improving Contextual Faithfulness of Large Language Models via Retrieval Heads-Induced Optimization](https://md.research.elamur.ai/free/en/papers/huang-2025-improving-contextual-faithfulness-large-language/)** *(2025 · 11 citations)* The paper addresses faithfulness hallucination in retrieval-augmented long-form question answering (LFQA), where a model writes paragraph-length answers containing claims that the retrieved documents do not support or that contradict them. 3. **[x1: Learning to Think Adaptively Across Languages and Cultures](https://md.research.elamur.ai/free/en/papers/ye-2026-x1-learning-think-adaptively-across/)** *(2026 · 1 citation)* Most reasoning LLMs think mainly in one dominant language, usually English, even when a question is posed in another language or depends on a specific culture. 4. **[Adaptive Backtracking for Privacy Protection in Large Language Models](https://md.research.elamur.ai/free/en/papers/yao-2026-adaptive-backtracking-privacy-protection-large/)** *(2026)* In retrieval-augmented generation, attackers can write prompts that make an LLM reveal private details from the documents it retrieves. 5. **[Fine-Mem: Fine-Grained Feedback Alignment for Long-Horizon Memory Management](https://md.research.elamur.ai/free/en/papers/ma-2026-fine-mem-fine-grained-feedback/)** *(2026)* LLM agents working on long-horizon tasks need a memory system that turns a stream of incoming text chunks into a compact, usable store. 6. **[ImplicitMemBench: Measuring Unconscious Behavioral Adaptation in Large Language Models](https://md.research.elamur.ai/free/en/papers/qin-2026-implicitmembench-measuring-unconscious-behavioral-adaptation/)** *(2026)* Existing memory benchmarks for LLM agents, such as LoCoMo, LongMemEval and MemoryAgentBench, test whether a model can deliberately retrieve stored facts when asked. ##
