CLoSD: Closing the Loop between Simulation and Diffusion for multi-task character control

ICLR 2025spotlight

Motion diffusion models and Reinforcement Learning (RL) based control for physics-based simulations have complementary strengths for human motion generation. The former is capable of generating a wide variety of motions, adhering to intuitive control such as text, while the latter offers physically…

Don't be so Negative! Score-based Generative Modeling with Oracle-assisted Guidance

ICML 2024poster

Score-based diffusion models are a powerful class of generative models, widely utilized across diverse domains. Despite significant advancements in large-scale tasks such as text-to-image generation, their application to constrained domains has received considerably less attention. This work address…

Understanding the Evolution of Linear Regions in Deep Reinforcement Learning

NeurIPS 2022accept

Policies produced by deep reinforcement learning are typically characterised by their learning curves, but they remain poorly understood in many other respects. ReLU-based policies result in a partitioning of the input space into piecewise linear regions. We seek to understand how observed region co…
