645d0ca767 ResidualGen mods
- Add filters_mid spec which allows a expansion->squeeze for the transformation layers.
- Add scale and bias AFTER the switch
- Remove identity transform (models were converging on this)
- Move attention image generation and temperature setting into new function which gets called every step with a save path

Just use the configurable one instead..

df1046c318 New arch: SwitchedResidualGenerator_arch
The concept here is to use switching to split the generator into two functions:
interpretation and transformation. Transformation is done at the pixel level by
relatively simple conv layers, while interpretation is computed at various levels
by far more complicated conv stacks. The two are merged using the switching
mechanism.

This architecture is far less computationally intensive that RRDB.

Not really sure it's a great fit for what is being done here.

be7982b9ae Add skip heads to switcher
These pass through the input so that it can be selected by the attention mechanism.

532704af40 Multiple modifications for experimental RRDB architectures
- Add LowDimRRDB; essentially a "normal RRDB" but the RDB blocks process at a low dimension using PixelShuffle
- Add switching wrappers around it
- Add support for switching on top of multi-headed inputs and outputs
- Moves PixelUnshuffle to arch_util

296135ec18 Add doResizeLoss to dataset
doResizeLoss has a 50% chance to resize the LQ image to 50% size,
then back to original size. This is useful to training a generator to
recover these lost pixel values while also being able to do
repairs on higher resolution images during training.

ae3301c0ea SwitchedRRDB work
Renames AttentiveRRDB to SwitchedRRDB. Moves SwitchedConv to
an external repo (neonbjb/switchedconv). Switchs RDB blocks instead
of conv blocks. Works good!

318a604405 Allow weighting of input data
This essentially allows you to give some datasets more
importance than others for the purposes of reaching a more
refined network.

dc17545083 Add RRDB Initial Stride
Allows downsampling immediately before processing, which reduces network complexity on
higher resolution images but keeps a higher filter count.
