Privacy-preserving Machine Learning and Data Analytics

Research Statement

Machine learning has recently been widely adopted in various applications, and such success is largely due to a combination of algorithmic breakthroughs, computation resource improvements, and especially the access to a large amount of diverse training data. However, such massive data usually contain privacy sensitive information such as medical and financial information of individuals. With the rise of ubiquitous sensing, personalization, and virtual assistants, users' privacy is at ever-increasing risk. Can we enable the power and utility of machine learning and data analytics while still ensuring users' privacy? Can we design privacy-preserving learning algorithms that can ensure privacy and guarantee high data utility? Can we design privacy-preserving data generative models for general downstream tasks?

Here we aim to explore novel techniques including differential privacy, homomorphic encryption, and information theoretic analysis to enable privacy-preserving machine learning and data analytics in practice. Our long-term goal is to both provide practical real-world solutions to privacy-preserving machine learning and data analytics and deepen the theoretical understanding of data privacy in the big data era.
