Subject: Inquiry Regarding DDN Benchmark Test Environment

[Yang-jaemin]

Dear authors,

First of all, thank you for your excellent research and for generously sharing your code.

I have a question regarding the DDN Benchmark Test mentioned in your paper. As far as I understand, the DDN benchmark is conducted in the AI2-THOR environment. However, it appears that only the Habitat-Sim-based code has been provided in this repository.

I would like to kindly ask the following two questions:

In your paper, did you implement InstructNav on top of the AI2-THOR environment when conducting experiments for the DDN benchmark?

If so, would it be possible for you to share the implementation of InstructNav for AI2-THOR?

Thank you again for your inspiring work. I look forward to your response.

Best regards,
Jaemin Yang
