How to Train PointGoal Navigation Agents on a (Sample and Compute) Budget
Erik Wijmans, Irfan Essa, Dhruv Batra
PointGoal navigation has seen significant recent interest and progress, spurred on by the Habitat platform and associated challenge. In this paper, we study PointGoal navigation un…
Contrastive Predictive Coding for Human Activity Recognition
Harish Haresamudram, Irfan Essa, Thomas Ploetz
Feature extraction is crucial for human activity recognition (HAR) using body-worn movement sensors. Recently, learned representations have been used successfully, offering promisi…
Semantic MapNet: Building Allocentric Semantic Maps and Representations from Egocentric Views
Vincent Cartillier, Zhile Ren, Neha Jain +3
We study the task of semantic mapping - specifically, an embodied agent (a robot or an egocentric AI assistant) is given a tour of a new environment and asked to build an allocentr…
Text as Neural Operator: Image Manipulation by Text Instruction
Tianhao Zhang, Hung-Yu Tseng, Lu Jiang +3
In recent years, text-guided image manipulation has gained increasing attention in the multimedia and computer vision community. The input to conditional image generation has evolv…
Analyzing Visual Representations in Embodied Navigation Tasks
Erik Wijmans, Julian Straub, Dhruv Batra +3
Recent advances in deep reinforcement learning require a large amount of training data and generally result in representations that are often over specialized to the target task. I…
