About the One-Way attention about peal HOT 1 OPEN

Hi, thanks for your interest in our work. In our paper, we didn't evaluate the inter-frame one-way attention method, focusing instead on the more meaningful global inter-frame cross-attention approach.

Cross-attention serves as a pivotal technique in facilitating feature exchange between two point clouds, thereby enabling the exploration of feature similarities between the source and target point clouds. Notably, global inter-frame cross-attention emerges as more insightful. Conversely, I think adopting inter-frame one-way attention introduces superfluous computational overhead, yielding limited benefits. Feel free to explore other methods.
