Qiyu Hou

R&D Engineer, focused on ML, CV, Language Models, and Document Intelligence. Former cuber.

Hi there, I’m Qiyu Hou (侯启予).

  • Welcome to my homepage.
  • I focus on ML, CV, Language Models, and Document Intelligence (Layout Analysis, OCR, Table Recognition, Diagram Recognition, and Document Understanding).
  • I’m working on document processing pipelines, and agentic systems (RAG, Knowledge Base, and Deep Research).
  • A long time ago, I was really into cubing. In 2016, I built a robot that could solve a Rubik’s Cube in one second. That same year, I ranked among the world’s top 10 in the Rubik’s Clock event, with a highest ranking of NR-2 and AsR-3.
  • I’m currently based in Nanjing, Jiangsu, China.
