Scale Up Strategically: Learning Compositional Generalization via Bias-Aware Evaluation and Data Collection for Robotic Manipulation

Yu Qi, Zhang Ye, Xinyi Xu, Yuxuan Lu, Amitoj Sandhu, Boce Hu, et al.

Compositional generalization is essential for robot to follow diverse instructions. However, pretrained policies are known to take shortcuts, deferring to salient cues rather than grounding language. We introduce a diagnostic framework that localizes this failure to individual \t…

Augmenting SOFA-2 with immune markers to capture dysregulated host response in patients with suspected infection

Yu Qi, Sun H, Chunhong Hou

Introduction The updated SOFA-2 score excludes the immune system due to specificity concerns, creating a conceptual gap given that sepsis is defined by a dysregulated host response. We hypothesized that augmenting SOFA-2 with widely available immune markers—white blood cell count…

Parse, Search, and Confirmation: Training-Free Aerial Vision-and-Dialog Navigation with Chain-of-Thought Reasoning and Structured Spatial Memory

Yu Qi, Hongyu Li, Shaofei Huang, Tianrui Hui, Yaxiong Wang, Lechao Cheng, et al.

In this paper, we tackle the Aerial Vision-and-Dialog Navigation (AVDN) task in the training-free setting for resource-efficient high-altitude UAV navigation.Naively applying MLLMs leads to unreliable navigation due to weak directional grounding and the lack of explicit spatial m…

Action Map Policy: Learning 3D Closed-loop Manipulation via Pixel Classification

Haojie Huang, Zhang Ye, Linfeng Zhao, Boce Hu, Mingxi Jia, Yu Qi, et al.

The action space poses a major challenge in robot learning, since it is often high-dimensional, can span long time horizons, and frequently admits multi-modal optimal solutions. A good choice of action representation and loss function can help to address these concerns, but there…
