Learning a Distance Metric for Structured Network Prediction
Description
Man-made or naturally-formed networks typically exhibit a high degree of structural
regularity. In this paper, we introduce the problem of structured network
prediction: given a set of n entities and a desired distribution for connectivity, return
a likely set of edges connecting the entities together in a network having the
specified degree distribution. Prediction is useful for initializing a network, augmenting
an existing network, and for filtering existing networks, when the structure
of the network is known. In order to capture the inter-dependencies amongst
pairwise predictions to learn parameters of our model, we build upon recent structured
output models. Novel in our approach is the use of partially labeled training
examples, and a network structure sensitive loss function. We present encouraging
results of the model predicting equivalence graphs and links in a social network.
