GoodDrag: Towards Good Practices for Drag Editing with Diffusion Models

ICLR 2025poster

In this paper, we introduce GoodDrag, a novel approach to improve the stability and image quality of drag editing. Unlike existing methods that struggle with accumulated perturbations and often result in distortions, GoodDrag introduces an AlDD framework that alternates between drag and denoising op…

Is LLMs Hallucination Usable? LLM-based Negative Reasoning for Fake News Detection

AAAI 2025technical

The questionable responses caused by knowledge hallucination may lead to LLMs' unstable ability in decision-making. However, it has never been investigated whether the LLMs' hallucination is possibly usable for generating negative reasoning to assist fake news detection. In this paper, we propose a…

Motion Priors Reimagined: Adapting Flat-Terrain Skills for Complex Quadruped Mobility

CoRL 2025poster

Reinforcement learning (RL)-based legged locomotion controllers often require meticulous reward tuning to track velocities or goal positions while preserving smooth motion on various terrains. Motion imitation methods via RL using demonstration data reduce reward engineering but fail to generalize…

Online Optimization of Central Pattern Generators for Quadruped Locomotion

IROS 2024

Typical legged locomotion controllers are designed or trained offline. This is in contrast to many animals, which are able to locomote at birth, and rapidly improve their locomotion skills with few real-world interactions. Such motor control is possible through oscillatory neural networks located in
