Vanilla GAN with Inversion and export to ONNX

Training a GAN on the EMNIST alphanumeric handwriting dataset, performing inversion, and exporting to ONNX. Network and training code copied almost verbatim from Diego Gomez's great PyTorch implementation.

I've written about this project in more detail here.

Untwisting EMNIST

EMNIST from PyTorch is mirrored and rotated 90 degrees, so I fix the data with some transforms.

Training

Nothing new to see here.

Inversion

Gradient-descent search through the generator's inputs in search of a good example of each character.

Exporting to ONNX

Worked just as advertised.
