4e44bca611 SPSR4
aka - return of the backbone! I'm tired of massively overparameterized generators
with pile-of-shit multiplexers. Let's give this another try..

19896abaea Clean up old SwitchedSpsr arch
It didn't work anyways, so why not?

313424d7b5 Add new referencing discriminator
Also extend the way losses work so that you can pass
parameters into the discriminator from the config file

6657a406ac Mods needed to support training a corruptor again:
- Allow original SPSRNet to have a specifiable block increment
- Cleanup
- Bug fixes in code that hasnt been touched in awhile.

dffc15184d More ExtensibleTrainer work
It runs now, just need to debug it to reach performance parity with SRGAN. Sweet.

59aba1daa7 LR switched SPSR arch
This variant doesn't do conv processing at HR, which should save
a ton of memory in inference. Lets see how it works.

0d070b47a7 Add simplified SPSR architecture
Basically just cleaning up the code, removing some bad conventions,
and reducing complexity somewhat so that I can play around with
this arch a bit more easily.

328afde9c0 Integrate SPSR into SRGAN_model
SPSR_model really isn't that different from SRGAN_model. Rather than continuing to re-implement
everything I've done in SRGAN_model, port the new stuff from SPSR over.

This really demonstrates the need to refactor SRGAN_model a bit to make it cleaner. It is quite the
beast these days..

eb11a08d1c Enable disjoint feature networks
This is done by pre-training a feature net that predicts the features
of HR images from LR images. Then use the original feature network
and this new one in tandem to work only on LR/Gen images.

e6e91a1d75 Add SRG4
Back to the idea that maybe what we need is a hybrid
approach between pure switches and RDB.

dbf6147504 Add switched discriminator
The logic is that the discriminator may be incapable of providing a truly
targeted loss for all image regions since it has to be too generic
(basically the same argument for the switched generator). So add some
switches in! See how it works!

0b7193392f Implement unet disc
The latest discriminator architecture was already pretty much a unet. This
one makes that official and uses shared layers. It also upsamples one additional
time and throws out the lowest upsampling result.

The intent is to delete the old vgg pixdisc, but I'll keep it around for a bit since
I'm still trying out a few models with it.

5f2c722a10 SRG2 revival
Big update to SRG2 architecture to pull in a lot of things that have been learned:
- Use group norm instead of batch norm
- Initialize the weights on the transformations low like is done in RRDB rather than using the scalar. Models live or die by their early stages, and this ones early stage is pretty weak
- Transform multiplexer to use u-net like architecture.
- Just use one set of configuration variables instead of a list - flat networks performed fine in this regard.

8a4eb8241d SRG3 work
Operates on top of a pre-trained SpineNET backbone (trained on CoCo 2017 with RetinaNet)

9048105b72 Break out SRG1 as separate network
Something strange is going on. These networks do not respond to
discriminator gradients properly anymore. SRG1 did, however so
reverting back to last known good state to figure out why.
