CRYPTEN: SecureMulti-PartyComputation MeetsMachineLearning

Secure multi-party computation (MPC) allows parties to perform computations on data while keeping that data private. This capability has great potential for machine-learning applications: itfacilitates training ofmachine-learning models on private data sets owned by different parties, evaluation of one party's private model using another party'sprivatedata,etc. Although arange ofstudies implement machine-learning models via secure MPC, such implementations are not yetmainstream.
