karpathy.github.io 研究 入门 Impact: 5/10

Karpathy reproduces LeCun's 1989 handwritten zip code recognition paper in PyTorch, revealing the nature of progress in deep learning over 33 years.

Key Points

  • Fully reproduced LeCun's 1989 end-to-end backpropagation milestone paper in PyTorch
  • The original network had ~1000 neurons but the paper structure already had all elements of modern DL papers
  • Same architecture with modern training methods achieves near-perfect accuracy today
