PAG: A projection-augmented graph approach to approximate nearest neighbor search (ANNS), super fast in both indexing and searching (5x HNSW), scaling up to high dimensionality (e.g., 3072) and retrieval size K (10 to 1000). Index size can be adjusted to meet memory requirement. [code]
ShapleyLaw: multilingual scaling laws for language models.
PKF: (ICLR 2026 Oral) angle testing for fast MIPS and ANNS. [code]
ELLMob: (ICLR 2026) An event-driven approach to human mobility generation using LLMs. [code]
FleS: (ICLR 2026) self-gated activation model for discriminative pattern recognition.
ASL: An adaptive layer-wise token pruning approach to KV cache reduction. [code]
LFP: (EMNLP 2025) We introduced the task of legal fact prediction and constructed a dataset for 657 litigation cases in China, covering 10 representative types of civil cases. [benchmark]
SAS: We are excited to announce the launch of SAS (Smart Agent Survey), a software designed for automated surveys utilizing LLM agents. Users can upload their questionnaires in various formats (DOCX, PDF, etc.). The software employs LLM agents to simulate respondent answers, making it a valuable tool for marketing strategies and policy-making.
We argue that LLM-based social simulations need clear boundaries to meaningfully contribute to social science research.
We analyze 7 security challenges that must be solved in cross-domain multi-agent LLM systems.
VLM & LLM fusion: We are excited to share some fascinating discoveries on combining Vision-Language Models (VLMs) with large language models (LLMs).
I am an associate professor with the Big Data Engineering Laboratory at Osaka University and a guest associate professor with the Database Laboratory at Nagoya University.
I graduated from the University of New South Wales in 2010, under the supervision of Xuemin Lin and Wei Wang.
My research interests focus on AI, NLP, computer simulation, data science, and data management. In detail, I explore the following research fields:
Agent-based modeling
Computational social science
Legal AI
Emergent language
Data lakes
