The authors propose TC–RAG, which they prove to be… 2. **[Recurrent Knowledge Identification and Fusion for Language Model Continual Learning](https://md.research.elamur.ai/free/en/papers/feng-2025-recurrent-knowledge-identification-fusion-language/)** *(2025 · 11 citations)* This paper tackles continual learning for large language models, where a model must absorb tasks one after another without losing earlier skills (catastrophic forgetting) while still benefiting from links between tasks (knowledge transfer). 3. **[Parenting: Optimizing Knowledge Selection of Retrieval-Augmented Language Models with Parameter Decoupling and Tailored Tuning](https://md.research.elamur.ai/free/en/papers/xu-2025-parenting-optimizing-knowledge-selection-retrieval/)** *(2025 · 9 citations)* Retrieval-augmented LLMs face two competing demands. They should trust retrieved evidence even when it contradicts what they memorized (adherence), and they should ignore retrieved passages that look relevant but are actually noise (robustness). Training aimed at one of these tends to hurt the other.
