Driving Down Link Energy and Driving Up Link Density in GPU Networks

GPU-accelerated computing systems, which power the AI revolution, rely on increasing amounts of off-chip I/O. To continue scaling, very dense integration of ultra-efficient optical transceivers alongside next-generation processor die will be needed.

Transform2Act: Learning a Transform-and-Control Policy for Efficient Agent Design

An agent's functionality is largely determined by its design, i.e., skeletal structure and joint attributes (e.g., length, size, strength). However, finding the optimal agent design for a given function is extremely challenging since the problem is inherently combinatorial and the design space is prohibitively large. Additionally, it can be costly to evaluate each candidate design which requires solving for its optimal controller. To tackle these problems, our key idea is to incorporate the design procedure of an agent into its decision-making process.

GLAMR: Global Occlusion-Aware Human Mesh Recovery with Dynamic Cameras

We present an approach for 3D global human mesh recovery from monocular videos recorded with dynamic cameras. Our approach is robust to severe and long-term occlusions and tracks human bodies even when they go outside the camera's field of view. To achieve this, we first propose a deep generative motion infiller, which autoregressively infills the body motions of occluded humans based on visible motions. Additionally, in contrast to prior work, our approach reconstructs human meshes in consistent global coordinates even with dynamic cameras.
