Hi, I’m Lim Hur, a machine learning engineer based in Singapore.

A place to think out loud and keep a record of things I’m learning. Its mostly:

  • Machine learning experiences: what I worked on, what surprised me, my learnings and takeaways
  • Technical notes: distilled from papers, blog posts, and open-source repositories I explored
  • Writing: rough thinking on ML research and systems I have been exploring

I want the focus of this page to be purely about AI/machine learning: training, inference, systems, and the research behind certain concepts

What I’m working on

  • Scaling and building BrandCodes, the infrastructure layer behind GS1 2D barcodes (raised $10k funding under NUS Enterprise, top 10% YC).
  • Research on consistency within video world models, paper publication soon!

Open source

  • WRBench: camera-controlled generation and diagnostic evaluation of video world models

Hackathons

  • SingHacks ‘25: Champions, $5k - decentralized AI marketplace facilitating x402 micropayments and smart contract verification
