Abstract
A method for privacy preservation for machine learning networks includes splitting a trained neural network into a first part and a second part. The first part is a privacy preservation (PP) encoder and the second part is a PP machine learning (ML) model. The method further includes retraining the PP encoder and the PP ML model. The method can improve artificial intelligence (AI) systems, optimize performance and support decision making in use cases including, but not limited to medical/healthcare, fraud detection, image recognition, predictive maintenance and connected vehicles.
