Struct RelationNetworks 

pub struct RelationNetworks<S = Untrained> { /* private fields */ }

Relation Networks for Few-Shot Learning

Relation Networks learn to predict relation scores between query and support samples. The network consists of an embedding module and a relation module that learns to compare objects and output relation scores.
