DemoDigits - davidrmiller/neural2d GitHub Wiki

The 5000 images of digits were created by a simple Python program. All the digits are the same size, but they vary a little in position and rotation (plus or minus 15 degrees), with random noise and blurring added.

Because of their artificial construction, they are not very representative of sets of digits found in the real world. Images captured from the real world may contain a greater variation in scale, rotation, position, and noise. This demo set serves only as a simple "hello world" test that the neural net is operating correctly.

Using the default topology.txt and inputData.txt config files, the neural net should learn how to classify these digits without using all 5000 samples. Once solved, the remaining input samples can serve as validation of the net's accuracy.
