Hello, I would like to ask about the paper architecture of bidirectional propagation. What is its written form or how is it named? I have searched through the code in pcdet/models/backbones_3d, pcdet/models/dense_heads, pcdet/models/detectors, and pcdet/models/model_utils, but I have not found any code that starts name with "Bi" or "propagation". Could anyone please let me know where the main architecture of this paper is written? Thank you.
