Cannot understand the classification mechanism of Sampling Oracle Network #16

Hello sir. :)

I have a question about section5.1 in your paper.

  1. What is the classification class mean? In the paper, each class corresponds to discretized segment along the ray; for every discrete ray segment, a high value indicates it should receive multiple samples. I'm confusing about the "class ray segment classified" and "receiving multiple samples" meaning.

  2. And how can multi-class target can be provided?.. The paper said it leads to binary classification.

Entirely, I can't understand the classification mechanism of the network.

Can you explain in detail?

Thanks!
