This is the product of me learning some pytorch and the math behind deep learning models. I put it in Excel for inference because it lets me see clearly how the math works out and I thought it would be funny to run this in a software much more prosiac than pytorch.
Before you ask. No it does not let you train a model. This is simply a pretrained model using Pytorch that was put in a nice accessible package for anyone to use (Excel).
To use this you have to copy and paste values into the interface tab of the Excel sheet. If you don't want to enter values one at a time then use the tkinter app to select a 28 x 28 pixel image. It will copy it to your clipboard so you can use in the spreadsheet.
I precompiled the tkinter app for windows users. Hope it works. Am I missing anything? Oh yea, small folder of test images from MNIST data set. If you hand draw images it will be less accurate. This isn't an insanely robust model. If you are using the copy paster then make your image white on black. See the samples.
