Is it possible to use this algorithm in an anchor-free network

Is it possible to use this algorithm in an anchor-free network such as FCOS? Thank you very much!

Hi @linsy-ai , PAA should be applicable to FCOS or any other anchor-free detectors, just like ATSS does. Although this codebase doesn't support it as-is, you can change this anchor-based assignment function to whatever assignment logic you want. I anticipate the performance will be similar to the current anchor-based assignment, as ATSS and other dynamic assignment algorithms show almost the same performance for both anchor-based and anchor-free models.
