Details

Cheng Lou has introduced Handwired, a toy project that transforms regular JavaScript code into a neural network. The tool operates without any training phase and produces exact outputs matching the original JavaScript program.

Key characteristics of Handwired include:

  • No training required: The conversion happens directly from code.
  • Exact outputs: Results match the source JavaScript program precisely.
  • Fully differentiable: The resulting neural network supports gradient-based operations.
  • Browser-based execution: Runs entirely in a browser without needing a GPU.
