Locally Private Estimation with Public Features

no code implementations22 May 2024 Yuheng Ma, Ke Jia, Hanfang Yang

Then we propose HistOfTree, an estimator that fully leverages the information contained in both public and private features.

Bagged Regularized $k$-Distances for Anomaly Detection

no code implementations2 Dec 2023 Yuchao Cai, Yuheng Ma, Hanfang Yang, Hanyuan Hang

We consider the paradigm of unsupervised anomaly detection, which involves the identification of anomalies within a dataset in the absence of labeled examples.
