ToolRec: Calibrated Preference Alignment for Query Recommendation in On-Device Assistants
Zihan Luo, Lingkui Chen, Ruike Zhang +5
Large Language Models (LLMs) have significantly advanced generative query recommendation. However, while alignment is crucial for tailoring LLMs to human preferences, existing alig…
Strengthening Bulow-Klemperer-Style Results for Multi-Unit Auctions
Moshe Babaioff, Yiding Feng, Zihan Luo
The classic result of Bulow and Klemperer (1996) shows that in multi-unit auctions with units and buyers whose values are sampled i.i.d. from a regular distribution,…
On the Fair Allocation to Asymmetric Agents with Binary XOS Valuations
Ziheng Chen, Bo Li, Zihan Luo +1
We study the problem of allocating indivisible goods among agents, where each agent's valuation is fractionally subadditive (XOS). With respect to AnyPrice Share (APS) fair…
Are Your Models Still Fair? Fairness Attacks on Graph Neural Networks via Node Injections
Zihan Luo, Hong Huang, Yongkang Zhou +3
Despite the remarkable capabilities demonstrated by Graph Neural Networks (GNNs) in graph-related tasks, recent research has revealed the fairness vulnerabilities in GNNs when faci…
Design and Characterization of Strategy-Proof Mechanisms for Two-Facility Game on a Line
Pinyan Lu, Zihan Luo, Jialin Zhang
We focus on the problem of placing two facilities along a linear space to serve a group of agents. Each agent is committed to minimizing the distance between her location and the c…
GraphInstruct: Empowering Large Language Models with Graph Understanding and Reasoning Capability
Zihan Luo, Xiran Song, Hong Huang +5
Improving the general capabilities of large language models (LLMs) is an active research topic. As a common data structure in many real-world domains, understanding graph data is a…
