Cost-Effective Numerical QA over Semi-Structured Table: Structuring, Resolution, Planning

Semi-structured tables encode rich semantic information through diverse layout elements, such as hierarchical row and column headers. Answering numerical questions over such data is challenging because it requires a joint effort of accurate structural understanding of tables, question uncertainty resolution, and comple...

GRAFT: Graph-Matched Retrieval and Fusion of Tables in Data Lakes

This work recast subgraph generation as a Markov decision process and learn a value function via implicit Q-learning on self-generated trajectories produced by a canonical compression operator that inverts the homomorphism, and introduces IGMS, a log-determinant reward that couples semantic relevance, structural compat...

Towards Efficient Reasoning in LLM-Based Recommender Systems via Model Merging

This work proposes the first model merging framework for reasoning compression in recommender systems, and proposes selective injection of the concise behaviour of the fast-thinking model into the slow-thinking model and reducing reasoning verbosity without compromising recommendation quality.
