A small neural network with only 38 + 12 hidden neurons which has been trained to read handwritten digits has been loaded on this page. It has an error rate of 1.71% on the MNIST dataset.
Please draw a digit with your mouse or with your finger on the canvas! In the table with the digits you will see how this network classifies what you draw.
