Design of Efficient and Privacy Preserving Machine Learning

• Caiwen Ding (University of Connecticut)

**Abstract**: The rapid deployment of machine learning system has witnessed various challenges such as high computation and privacy/security concerns. In this talk, we will first discuss the current challenges and advances in efficient machine learning. We will present several machine learning accelerations through algorithm-hardware codesign, on various computing platforms such as GPU, MCU, and ReRAM. On the other hand, Machine-Learning-As-A-Service (MLaaS) provides cloud-based tools to mitigate the cost and risk of building individual ML platforms. Privacy-preserving machine learning (PPML) serves as a good solution to protect sensitive user data. However, the introduced crypto-primitives come at extra high computation and communication overhead and potentially prohibit the machine learning popularity. We will present a systematic acceleration framework that enables low latency, high energy efficiency & accuracy, and security-guaranteed machine learning. **Bio**: Caiwen Ding is an assistant professor in the Department of Computer Science & Engineering at the University of Connecticut (UConn).
