The Normal Distributions Indistinguishability Spectrum and its Application to Privacy-Preserving Machine Learning

no code implementations3 Sep 2023 Yun Lu, Malik Magdon-Ismail, Yu Wei, Vassilis Zikas

We apply the NDIS theorem to derive DP mechanisms for queries with normally-distributed outputs -- i. e., Gaussian Random Projections (RP) -- and for more general queries -- i. e., Ordinary Least Squares (OLS).

City Metro Network Expansion with Reinforcement Learning

no code implementations25 Sep 2019 Yu Wei, Minjia Mao, Xi Zhao, Jianhua Zou

In this method, we formulate the metro expansion as a process of sequential station selection, and design feasibility rules based on the selected station sequence to ensure the reasonable connection patterns of metro line.
