While working through the Google YouTube series on machine learning I watched episode six Train an Image Classifier with Tensorflow for Poets. Since I create notebooks for every episode I did this here, too. The following text is taken from this notebook and it is a short tutorial on how to implement an image classifier with tensorflow in a very short amount of time. You can transfer this knowledge to every other image classification task without much effort. You can find the original python notebook here and my other notebooks on my iPython Notebook page.
I just added a new page called iPython Notebooks. You can find a collection of my personal iPython Notebooks there. These notebooks are a very cool tool of the python community that makes it easy to share your code. On top of that they also provide inline graphs and formated text.
