This paper presents TransNet, a new method for transfer learning in community detection of network data.
TransNet aims to improve the clustering performance of the target network by utilizing auxiliary source networks that are privacy-preserved and locally stored across various sources.
To achieve privacy preservation, the edges of each locally stored network are perturbed using the randomized response mechanism, ensuring differential privacy.
By proposing an adaptive weighting method and regularization technique, TransNet effectively aggregates the eigenspaces of the source networks, incorporating the effects of privacy and heterogeneity.
