Everyone is looking towards TensorFlow to begin their deep learning journey. One issue that arises for aspiring deep learners is that it is unclear how to use their own datasets. Tutorials go into great detail about network topology and training (rightly so), but most tutorials typically begin with and never stop using the MNIST dataset. Even new models people create with TensorFlow, like this Variational Autoencoder, remain fixated on MNIST. While MNIST is interesting, people new to the field already have their sights set on more interesting problems with more exciting data (e.g. Learning Clothing Styles).
In order to help people more rapidly leverage their own data and the wealth of unsupervised models that are being created with TensorFlow, I developed a solution that (1) translates image datasets into a file structured similarly to the MNIST datasets (github repo) and (2) loads these datasets for use in new models.
To solve the first part, I modified existing solutions that demonstrate how to decode the MNIST binary file into a csv file and allowed for the additional possibility of saving the data as images in a directory (also worked well for testing the decoding and encoding process).
The TensorFlow tutorials allow you to import the MNIST data with a simple function call. I modified the existing input_data function to support the loading of training and testing data that have been created using the above procedure: input_any_data_unsupervised. When using this loading function with previously constructed models, remember that it does not return labels and those lines should be modified (e.g. the call to next_batch in line 5 of this model).
A system for supervised learning would require another encoding function for the labels and a modified input function that uses the gzipped labels.
I hope this can help bridge the gap between starting out with TensorFlow tutorials with MNIST and diving into your own problems with new datasets. Keep deeply learning!
