Why use two optimiziers?

[zhangpur]

Thanks for sharing this great work. I don't understand why introducing 'optimizer_2' for optimizing the complete trajectory decoder, could you give some directions? Thanks!

I have the same question

Using one optimizer for both goal scoring module and trajectory completion module will slightly affect the performance of the goal scoring module, so we introduce an additional optimizer for the trajectory completion module.
