Training Differentially Private Models with Secure Multiparty Computation

no code implementations5 Feb 2022 Sikha Pentyala, Davis Railsback, Ricardo Maia, Rafael Dowsley, David Melanson, Anderson Nascimento, Martine De Cock

We address the problem of learning a machine learning model from training data that originates at multiple data owners while providing formal privacy guarantees regarding the protection of each owner's data.

Privacy-Preserving Training of Tree Ensembles over Continuous Data

no code implementations5 Jun 2021 Samuel Adams, Chaitali Choudhary, Martine De Cock, Rafael Dowsley, David Melanson, Anderson C. A. Nascimento, Davis Railsback, Jianwei Shen

In this paper we propose three more efficient alternatives for secure training of decision tree based models on data with continuous features, namely: (1) secure discretization of the data, followed by secure training of a decision tree over the discretized data; (2) secure discretization of the data, followed by secure training of a random forest over the discretized data; and (3) secure training of extremely randomized trees (``extra-trees'') on the original data.

High Performance Logistic Regression for Privacy-Preserving Genome Analysis

1 code implementation13 Feb 2020 Martine De Cock, Rafael Dowsley, Anderson C. A. Nascimento, Davis Railsback, Jianwei Shen, Ariel Todoki

In this paper, we present a secure logistic regression training protocol and its implementation, with a new subprotocol to securely compute the activation function.
