Building an Image Recognizing Spreadsheet

The team at Concepts Illuminated built an image recognizing spreadsheet to better understand Convolutional Neural Networks. The sheet can recognize the letters X, T, and L. Creating it really illuminates the details, especially how a deep convolution layer can build off the previous layers.

There is a two-part series that walks through building that spreadsheet.

The fully implemented sheet is at https://bit.ly/CNNSheet3 if you just want to jump to the end.

If you are just getting into neural networks, maybe look at our previous series on building and training a traditional neural network in a spreadsheet:
