The meaning of a variable in code #9

Closed YAOMOREN closed 3 years ago

YAOMOREN commented 3 years ago

I don't understand what the features1, fuse_global, global_feature1, REFs1 stand for in the code, especially fuse_global, global_feature1.Can you explain that to help me understand the paper better

raoyongming commented 3 years ago

Sorry for the late response.

feature1 is the list of features from different abstraction levels fuse_global is the summarized global feature (see f in Eq.7 in our paper) global_feature1 is the global feature of the last abstraction level REFs1 is the list of features from the first two abstraction levels (local features)

The definition of these variables can be found here.
