Notes

Note 1: The padding on matrix

  • This article will show how to use the "pad()" function of Numpy, and utilize it in building convolutional neural networks.
  • File Name: numpy_note-01-Padding-function-in-numpy.ipynb

Note 2: Save the variables as .npz file

  • We provided how to save the variables as a npz file, and demonstrated how to load npz file. In addition to this, we also compared the time costs of numpy.savez and numpy.savez_compressed.
