Change Log

Personal site update log (not to be confused with CHANGELOG.md, which tracks the upstream Minimal Mistakes theme).

2026-08-02

• Added new post: “Basic Neural Network from Scratch: NumPy vs PyTorch” (_posts/2026-08-02-Neural_Network_From_Scratch_with_NumPy_and_PyTorch.md)
  • Single-hidden-layer NN (2→6→1, tanh/sigmoid) trained on a non-linearly-separable XOR-pattern dataset
  • Forward/backward propagation implemented and executed both by hand in NumPy and via autograd in PyTorch
  • Companion notebook: notebooks/2026-08-02-Neural_Network_From_Scratch_with_NumPy_and_PyTorch.ipynb
  • Generated plots stored under assets/images/NN_Scratch/
• Added MathJax to _includes/head/custom.html so kramdown-rendered math ($$...$$ block, $...$ inline) displays site-wide
  • Initial config only registered \(...\) as an inline delimiter; fixed to also register $...$, since kramdown leaves inline math in that form untouched
• Translated the new post/notebook’s explanatory text and code comments from Korean to English (content and generated outputs unchanged)
• Added PROJECT_NOTES.md documenting the repo’s directory structure and posting workflow
