Title: DAUnTLeSS: Data Augmentation and Uniform Transformation for Learning with Scalability and Security

We revisit private optimization and learning from an information processing view. Different from the classic cryptographic framework of operation-by-operation obfuscation, a private learning and inference framework via either data-dependent or random transformation on the sample domain is proposed, along with a security analysis framework, termed probably approximately correct (PAC) inference resistance, which bridges the information loss in data processing and prior knowledge.

We study the applications of such a framework from generalized linear regression models to modern learning techniques, such as deep learning. We explore the advantages of this new random transform approach with respect to underlying privacy guarantees, computational efficiency and utility for neural networks.

Hanshen Xiao, PhD candidate at MIT, is the primary author of this work.
