Surface-Aligned Neural Radiance Fields for Controllable 3D Human Synthesis

CVPR 2022poster

We propose a new method for reconstructing controllable implicit 3D human models from sparse multi-view RGB videos. Our method defines the neural scene representation on the mesh surface points and signed distances from the surface of a human body mesh. We identify an indistinguishability issue that…

Distributed Reinforcement Learning of Targeted Grasping with Active Vision for Mobile Manipulators

IROS 2020poster

Developing personal robots that can perform a diverse range of manipulation tasks in unstructured environments necessitates solving several challenges for robotic grasping systems. We take a step towards this broader goal by presenting the first RL-based system, to our knowledge, for a mobile manipu…

A Wrapped Normal Distribution on Hyperbolic Space for Gradient-Based Learning

ICML 2019oral

Hyperbolic space is a geometry that is known to be well-suited for representation learning of data with an underlying hierarchical structure. In this paper, we present a novel hyperbolic distribution called hyperbolic wrapped distribution, a wrapped normal distribution on hyperbolic space whose dens…

Model-Based Reinforcement Learning via Meta-Policy Optimization

CoRL 2018

Model-based reinforcement learning approaches carry the promise of being data efficient. However, due to challenges in learning dynamics models that sufficiently match the real-world dynamics, they struggle to achieve the same asymptotic performance as model-free methods. We propose Model-Based Meta
