AESPA: Accuracy Preserving Low-degree Polynomial Activation for Fast Private Inference [article]

Jaiyoung Park and Michael Jaemin Kim and Wonkyung Jung and Jung Ho Ahn
2022 arXiv   pre-print
Hybrid private inference (PI) protocol, which synergistically utilizes both multi-party computation (MPC) and homomorphic encryption, is one of the most prominent techniques for PI.  ...  Although a standard non-linear activation function can generate higher model accuracy, it must be processed via a costly garbled-circuit MPC primitive.  ...  Given the pre-trained neural network, Delphi replaces some ReLUs with quadratic approximation and retrains the neural network, which allows them to utilize a less costly BT primitive.  ...
