Learning to Ideate for Machine Learning Engineering Agents

Yunxiang Zhang, Kang Zhou, Zhichao Xu +5

Existing machine learning engineering (MLE) agents struggle to iteratively optimize their implemented algorithms for effectiveness. To address this, we introduce MLE-Ideator, a dua…

Black-Box Visual Prompt Engineering for Mitigating Object Hallucination in Large Vision Language Models

Sangmin Woo, Kang Zhou, Yun Zhou +4

Large Vision Language Models (LVLMs) often suffer from object hallucination, which undermines their reliability. Surprisingly, we find that simple object-based visual prompting --…
