Teaching

Semester 2 (Stage 3): EEE3027 - Integrated Circuits and Embedded Systems

In this Stage 3 BEng/MEng course, I teach the use of hardware/software co-design and the principles of concurrency in embedded systems. The module is co-taught by Dr Fei Xia and Professor Alex Yakovlev.

EEE8161: Machine Learning for Engineering Applications

In this MSc course (led by Dr Kabita Adhikari), I introduced theory and practice of several well known machine learning principles, such as decision trees, random forests, k-nearest neighbour classifiers, support vector machines and neural networks. I also introduce Tsetlin Machine as an emerging machine learning principle applied in energy-efficient and discernible systems.
