how do i run it?

Difficulty · hard time til it works · 1h+

Builds on existing detection transformer frameworks and needs GPU compute for training, though pre-trained weights let you skip training from scratch.

prompts (copy fr)

prompt 1
Explain how SFA's domain queries align scene understanding across different environments.
prompt 2
Walk me through using SFA's pre-trained weights to adapt my object detector to foggy conditions.
prompt 3
How does SFA's consistency check keep predictions stable during domain adaptation training?
