A registration apparatus is configured to access a network formed of a set of first nodes and first edges, the first nodes each representing a first feature vector including a plurality of elements, the first edges each coupling two first nodes representing two first feature vectors to each other based on two first feature vectors, a processor in the registration apparatus is configured to execute: obtaining processing of obtaining a second feature vector; and registration processing of registering a second node representing the second feature vector to the network based on a similarity relationship among third feature vectors in a set of third feature vectors included in the set of first feature vectors, and coupling the second node and a third node representing the third feature vector to each other with a second edge, the number of third feature vectors being smaller than the number of first feature vectors.
