GOES

  • Adding better plotting of intermediate values
  • Tweaking the margins, which is not adjusted by the plt.margins() method. It’s actually plt.subplots_adjust(). That took entirely too long to find.
  • Got the plot working, and it is super cool:

epochs

Tried a lower latent dimension (8) and fewer neurons in the generator (32). Not really any different. It does take longer to stabilize though.

epochs

  • Upping the strides on the discriminator to 4. Definitely less mode collapse

epochsNoise_trainedacc_loss

  • Trying a stride of 8. That seems even better, though there is this funky artifact on the right. Going to try it with 10,000 epochs:

Noise_trained

  • Nope, no better. Sticking with the stride of 4. And 5,000 epochs seems to be enough to settle. This really looks a lot like the previous stride=4 run above:

epochsNoise_trainedacc_loss

  • Ok, back to Advanced Deep Learning with Keras and GANS
  • The last part of chapter 4 covered conditional GANS, or CGANS. I think that could be very nice to associate a particular type of noise with the state on a sim. For example, daylight vs. eclipse. It looks pretty straightforward, just the concatenation of a state to the input and discriminator vectors:

CGAN
