Profile
database systems · data mining · trustworthy AI · time-series · deployable systems
Anthony K. H. Tung is a Professor at the National University of Singapore, working across database systems, data mining, information retrieval, and trustworthy, deployable AI for operational decision-making.
His current unifying theme is Prudent AI for High-Stakes, Data-Scarce Operational Systems: right-sized, interpretable, auditable, and robust AI for domains where data are scarce, labels are limited, events are rare, and deployment constraints matter.
The program threads interpretable methods into reliable systems and lightweight, deployable tools across text, time-series, tabular, and longitudinal data — connecting methods, systems, and measurable operational outcomes across manufacturing, cybersecurity, and finance/crypto. A second strand views AI as connective infrastructure that elevates collective human potential.

A guiding text
To be constantly learning and practicing what you learn — isn't it the greatest joy of all? To have bosom friends who share your learning from all over the world — doesn't it bring the greatest happiness? To be unknown to people and yet remain undisturbed — isn't that the mark of the most virtuous? — The Analects of Confucius (论语), Chapter 1:1
The world is beautiful because there are similarities and differences. Similarities let us understand one another; differences make each of us unique and interesting.
In human relationships we respect friendship and seniority; in science and mathematics, we respect the truth.
It is more satisfying to help the weak to improve than to make the strong stronger.
The beauty of life comes from having choices among the no-choices — and from what we do with the talent we are given.
