CLIP-Nav: Using CLIP for Zero-Shot Vision-and-Language Navigation

Vishnu Sashank Dorbala, Gunnar Sigurdsson, Robinson Piramuthu +2

Household environments are visually diverse. Embodied agents performing Vision-and-Language Navigation (VLN) in the wild must be able to handle this diversity, while also following…
