Hi， I hvae one question about the paper

[QingTianNNN]

In your paper, you said "Our novel multimodal geometric reconstruction algorithm and reciprocal training technique create a supervisory signal for the self-supervised neural network." I was wondering what is that technique and how to implement the reciprocal training technique. My understanding is that through this training technique, information can be exchanged between different modules, I don't know if this is correct, if it is correct, please tell me how to implement this technique, if not, please correct me.
