Question about multi-task

[rOtking]

I have a question, does the model can support multi-task? Or the architecture can support multi-task, but you can only choose one specific task when you train.

[tomztyang]

Yes. You can train one model on multi-task simultaneously with accordingly set query positions.

@tomztyang Thank you for your reply. And i want to know, does one query can be used for multi-task with different head? Or the querys are grouped, for example, some querys are used for detection, some querys are used for segmentation?

[tomztyang]

In my opinion, a query represents a position. You can use features of this position for detection, or for segmentation, or for both simultaneously, which depend on the head. If you wish to use the features for multi-tasking, just add multi-task head after obtaining the feature of this position. That's my though.
