PadaOne

With PadaOne you can create and train your own basic neural network for digit recognition, from 0 to 9. You can create your own training set with images that you can draw in the same app. You need to have between 10 and 30 images and for each digit to be able to train your network.
If you just want to test, you can also recognize digits directly with the test neural network that comes pre-installed.
