GenPilot: A Multi-Agent System for Test-Time Prompt Optimization in Image Generation

EMNLP 2025

Text-to-image synthesis has made remarkable progress, yet accurately interpreting complex and lengthy prompts remains challenging, often resulting in semantic inconsistencies and missing details. Existing solutions, such as fine-tuning, are model-specific and require training, while prior automatic

LEARN: Knowledge Adaptation from Large Language Model to Recommendation for Practical Industrial Application

AAAI 2025technical

Contemporary recommendation systems predominantly rely on ID embedding to capture latent associations among users and items. However, this approach overlooks the wealth of semantic information embedded within textual descriptions of items, leading to suboptimal performance and poor generalizations.…

Agile and Versatile Robot Locomotion via Kernel-based Residual Learning

ICRA 2023poster

This work developed a kernel-based residual learning framework for quadrupedal robotic locomotion. Ini-tially, a kernel neural network is trained with data collected from an MPC controller. Alongside a frozen kernel network, a residual controller network is trained using reinforcement learning to ac…

Modular Neural Network Policies for Learning In-Flight Object Catching with a Robot Hand-Arm System

IROS 2023poster

We present a modular framework designed to enable a robot hand-arm system to learn how to catch flying objects, a task that requires fast, reactive, and accurately-timed robot motions. Our framework consists of five core modules: (i) an object state estimator that learns object trajectory prediction…
