## AI overview

This tutorial builds and tests an OCR program that recognizes handwritten letters from a photo using a convolutional deep learning model. It shows how differences between real-world input and training data can cause recognition failures, including difficulty recognizing a handwritten "h".

## Source excerpt

This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub! The previous chapters have often mentioned the chasm between "deep learning models that work on my data" and "it actually works in the real world". It is perhaps for this reason that almost all demos and YouTube tutorials you find online never do any real world testing.
