VisAudit: Evaluating Multimodal Agents for Visual Diagnosis and Repair

Shicheng Liu, Adam Kahirov, Qi Zhang +5

Multimodal agents are increasingly used for data visualization tasks but remain limited in autonomous review. Unlike humans, they may fail to recognize when a visualization is inco…

How Much Reasoning Do Retrieval-Augmented Models Add beyond LLMs? A Benchmarking Framework for Multi-Hop Inference over Hybrid Knowledge

Junhong Lin, Bing Zhang, Song Wang +4

Large language models (LLMs) continue to struggle with knowledge-intensive questions that require up-to-date information and multi-hop reasoning. Augmenting LLMs with hybrid extern…

Reasoning of Large Language Models over Knowledge Graphs with Super-Relations

Song Wang, Junhong Lin, Xiaojie Guo +3

While large language models (LLMs) have made significant progress in processing and reasoning over knowledge graphs, current methods suffer from a high non-retrieval rate. This lim…

Aggregating Funnels for Faster Fetch&Add and Queues

Younghun Roh, Yuanhao Wei, Eric Ruppert +3

Many concurrent algorithms require processes to perform fetch-and-add operations on a single memory location, which can be a hot spot of contention. We present a novel algorithm ca…
