BAMAS: Structuring Budget-Aware Multi-Agent Systems

AAAI 2026technical

Large language model (LLM)-based multi-agent systems have emerged as a powerful paradigm for enabling autonomous agents to solve complex tasks. As these systems scale in complexity, cost becomes an important consideration for practical deployment. However, existing work rarely addresses how to struc

LLM-Powered Test Case Generation for Detecting Bugs in Plausible Programs

ACL 2025long

Detecting tricky bugs in plausible programs, those that pass existing test suites yet still contain bugs, remains a significant challenge in software testing. To address this problem, we propose TrickCatcher, an LLM-powered approach to generating test cases for uncovering bugs in plausible programs.…

Personality-Guided Code Generation Using Large Language Models

ACL 2025long

Code generation, the automatic creation of source code from natural language descriptions, has garnered significant attention due to its potential to streamline software development. Inspired by research that links task-personality alignment with improved development outcomes, we conduct an empirica…

Emoji-Powered Representation Learning for Cross-Lingual Sentiment Classification (Extended Abstract)

IJCAI 2020poster

Sentiment classification typically relies on a large amount of labeled data. In practice, the availability of labels is highly imbalanced among different languages. To tackle this problem, cross-lingual sentiment classification approaches aim to transfer knowledge learned from one language that has…
