Learning State-Aware Visual Representations from Audible Interactions

We propose a self-supervised algorithm to learn representations from untrimmed, egocentric videos containing audible interactions.
Our method uses the audio signals in two unique ways: (1) to identify moments in time that are conducive to better self-supervised learning
and (2) to learn representations that focus on the visual state changes caused by audible interactions.

A self-supervised method to complete the incomplete, partial point clouds for real-world settings like LiDAR where ground truth complete point cloud
annotations are unavailable. We achieve this via inpainting where a region of the point cloud is removed and the network is trained to complete this removed region.

Short Paper
A method of training scene flow that uses two self-supervised losses, based on nearest neighbors and cycle consistency.
These self-supervised losses allow us to train our method on large unlabeled autonomous driving datasets.
