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.

Round and Communication Balanced Protocols for Oblivious Evaluation of Finite State Machines

no code implementations20 Mar 2021 Rafael Dowsley, Caleb Horst, Anderson C. A. Nascimento

We propose protocols for obliviously evaluating finite-state machines, i. e., the evaluation is shared between the provider of the finite-state machine and the provider of the input string in such a manner that neither party learns the other's input, and the states being visited are hidden from both.

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.
