Yu Xi Chau

I build efficient AI systems that organizations can use, govern and trust.

The work on this site is organised around three connected questions: how to build efficient AI systems, how organisations govern them, and where they create useful results.

  • AI systems — models, data, tools, workflows, reliability, and production engineering.
  • AI governance — guardrails, accountability, risk, policy, and organisational decisions.
  • AI application — practical use of AI in complex organisations and the human judgement around it.

Personal projects in history, mathematics, and data remain available under Projects. They are secondary to these professional themes, but they show the interests behind the work.
