Performance drops on 256x256 images

[JoshVarty]

Here is the performance of our model:

Size (px)	Epochs	URL	Accuracy	# Runs
128	5	Inpainting	40.87%	5
128	20	Inpainting	61.15%	3
128	80	Inpainting	62.18%	1
128	200	Inpainting	62.03%	1

Size (px)	Epochs	URL	Accuracy	# Runs
192	5	Inpainting	39.33%	5
192	20	Inpainting	64.62%	3
192	80	Inpainting	66.76%	1
192	200	Inpainting	67.12%	1

Size (px)	Epochs	URL	Accuracy	# Runs
256	5	Inpainting	19.88%	5
256	20	Inpainting	47.26%	3
256	80	Inpainting	63.55%	1
256	200	Inpainting	67.47%	1

Notice how performance decreases at 5, 20 and 80 epochs for the 256x256 images (compared to 192x192 images.

Performance is also down slightly at 5 epochs for the 192x192 images (compared to 128x128 images).

We should try to investigate this and see what's going on.
