Vision-and-Language Navigation: Interpreting Visually-Grounded Navigation Instructions in Real Environments [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2017 A robot that can carry out a natural-language instruction has been a dream since before the Jetsons cartoon series imagined a life of leisure mediated by a fleet of attentive robot helpers. It is a dream that remains stubbornly distant.
