Object Goal Navigation with Recursive Implicit Maps

Understand

Object goal navigation aims to navigate an agent to locations of a given object category in unseen environments.

• Classical methods explicitly build maps of environments and require extensive engineering while lacking semantic information for object-oriented exploration.
• On the other hand, end-to-end learning methods alleviate manual map design and predict actions using implicit representations.
• Such methods, however, lack an explicit notion of geometry and may have limited ability to encode navigation history.
