Lars Yencken


Profile

I'm an engineer and former researcher in human languages, machine learning and web systems. I love making, discovering and writing.

For my PhD, I modelled language learners' knowledge so as to make richer tools for studying Japanese and Chinese. At NICTA, I analysed medical texts using machine learning, sparking my interest in larger datasets. I joined 99designs to learn how to serve larger audiences, and stayed to delve into the rich data that comes with customer interaction.

I believe that a mathematical beauty underpins our world. I stand for kindness, reason, collaboration, openness and growth.

Projects

  • Great Language Game: learn to distinguish between spoken languages
  • Simsearch: an open source visual similarity search for Japanese kanji.
  • FOKS: an intelligent dictionary for learners of Japanese.
  • Kanji Tester: a study tool for JLPT levels 3 and 4 centred around adaptive testing.

Open source

  • marelle: test-driven sysadmin through logic programming
  • colorific: library for detecting significant color in designs
  • anytop: an ncurses frequency visualisation from streaming input.
  • doko: a command-line tool for determining your current location
  • cjktools: a Python library for working with Japanese and Chinese dictionaries.
