X-Router: Decoupling Knowledge and Reasoning for Cost-Effective LLM Inference (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing adaptive methods focus on a single axis, overlooking evidence need and reasoning depth are only partially correlated. |
| Approach: | They propose a dual-axis routing framework that separates retrieval necessity from reasoning necessity under a user-defined cost–quality trade-off. |

Copied to clipboard
| Challenge: | Existing approaches ignore the overlap knowledge across datasets, preventing models from achieving better performance. |
| Approach: | They propose to divide the EAE knowledge into overlap knowledge across datasets and specific knowledge of the target dataset. |

AdapShot: Adaptive Many-Shot In-Context Learning with Semantic-Aware KV Cache Reuse (2026.acl-long)
Copied to clipboard
| Challenge: | Existing methods for In-Context Learning (ICL) rely on a predetermined number of shots, leading to insufficient context or noise. |

A Reproducibility Study on Quantifying Language Similarity: The Impact of Missing Values in the URIEL Knowledge Base (2024.naacl-srw)
Copied to clipboard
| Challenge: | URIEL aggregates linguistic information for 4,005 languages and computes distances based on this information. |
| Approach: | They propose to use a typological knowledge base to quantify language similarity to investigate URIEL's ambiguity in calculating language distances and handling missing values. |
| Outcome: | The URIEL knowledge base does not provide information about typological features for 31% of the languages it represents, undermining the reliability of the database, especially on low-resource languages. |
