- A relation network consists of two important functions: the embedding function, denoted by , and the relation function, denoted by .
- Once we have the feature vectors of the support set, , and query set, , we combine them using an operator, . Here, can be any combination operator; we use concatenation as an operator to combine the feature vectors of the support set and the query set—that is, .
- The relation function, , will generate a relation score ranging from 0 to 1, representing the similarity between samples in the support set, , and samples in the query set, .

Our loss function can be represented as follows:
- In matching networks, we use two embedding...
