HRNet: Differentially Private Hierarchical and Multi-Resolution Network for Human Mobility Data Synthesization

arXiv:2405.08043v1 Announce Type: new
Abstract: Human mobility data offers valuable insights for many applications such as urban planning and pandemic response, but its use also raises privacy concerns. In this paper, we introduce the Hierarchical and Multi-Resolution Network (HRNet), a novel deep generative model specifically designed to synthesize realistic human mobility data while guaranteeing differential privacy. We first identify the key difficulties inherent in learning human mobility data under differential privacy. In response to these challenges, HRNet integrates three components: …
