Benchmarking LLMs’ Mathematical Reasoning with Unseen Random Variables Questions

AAAI 2026technical

Recent studies have raised significant concerns regarding the reliability of current mathematical benchmarks, highlighting key limitations such as simplistic design and potential data contamination that undermine evaluation accuracy. Consequently, developing a reliable benchmark that effectively eva

LLM Collaborative Filtering: User-Item Graph as New Language

AAAI 2026technical

In collaborative filtering, learning effective embeddings for users and items from interaction data remains a central challenge. While recent efforts leverage large language models (LLMs) to enhance collaborative filtering, two critical limitations persist: (1) Efficiency: LLM-based inference is sig

LinearRAG: Linear Graph Retrieval Augmented Generation on Large-scale Corpora

ICLR 2026poster

Retrieval-Augmented Generation (RAG) is widely used to mitigate hallucinations of Large Language Models (LLMs) by leveraging external knowledge. While effective for simple queries, traditional RAG systems struggle with large-scale, unstructured corpora where information is fragmented. Recent advance…

SNIAE-SSE Deformation Mechanism Enabled Scalable Multicopter: Design, Modeling and Flight Performance Validation

ICRA 2020poster

This paper focuses on designing, modeling and validating a novel scalable multicopter whose deformation mechanism, called SNIAE-SSE, relies on a combination of simple non-intersecting angulated elements (SNIAEs) and straight scissor-like elements (SSEs). The proposed SNIAE-SSE mechanism has the adva…
