A Recurrent Vision-and-Language BERT for Navigation

Hong, Yicong, Wu, Qi, Qi, Yuankai et al.

Understand

Accuracy of many visiolinguistic tasks has benefited significantly from the application of vision-and-language(V&L) BERT.

  • However, its application for the task of vision-and-language navigation (VLN) remains limited.
  • One reason for this is the difficulty adapting the BERT architecture to the partially observable Markov decision process present in VLN, requiring history-dependent attention and decision making.
  • In this paper we propose a recurrent BERT model that is time-aware for use in VLN.
