  • Summary: Machine learning (ML), and especially its subset deep learning, are being successfully used in native platforms in advanced computationally-heavy areas such as image recognition, speech recognition, and natural language processing. Currently, the Web is unable to support advanced machine learning use cases in a performant manner due to lack of optimized low-level APIs for machine learning.
  • Type of session: WebML-enabled Chromium proof-of-concept demo and results, short presentation, discussion.

Adding them should not trigger rendering (style calc, layout, etc) until needed. See explainer
  • Type of session: Short presentation followed by discussion
  • Goals: Introduce Searchable Invisible DOM


  • Proposer: Tzviya Siegman Tzviya Siegman, Natasha Rooney , Angel Li~~~~
