Digit recognition interface with an RPN calculator

This post is a follow-up of my previous blog post “Classification of handwritten†digits” about recognition of digit drawings.

A friend of mine pointed out that “the recognition of digits was one of the assignments in the Coursera Machine Learning course, using Matlab or Octave.” (Octave is free, open source version of Matlab.)

So I decided to do a digit recognition and interpretation interactive interface in/with Mathematica, which is not something that can be done with Matlab or Octave. Here is a link to a video demonstrating the interface: http://youtu.be/iPF5Apa6OjY .

Here is a screenshot:
