Topic 3: Learning on Chips

Machine learning is a powerful computer science technique which can derive knowledge from big data, and provides prediction and matching. Since nanometer VLSI CAD problems have extremely high complexity and gigantic data, there has been a surge recently in applying and adapting machine learning techniques in VLSI CAD.

Topic 6: Emerging Challenges

Cyber-physical system (CPS) addresses the close interactions and feedback loop between the cyber components such as sensing systems and the physical components such as varying environment and energy systems. Currently we are working on data regression and calibration in smart building environment. On ther other hand, we are also working on improving the security for hardware systems.
