Laplacian Pyramid Generative Adversarial Networks

Loss Function

  • used sce loss for G/D nets.

Architecture Networks

  • Similar as LAPGAN paper.
DIFFS LAPGAN Paper ME
Weight initializer normal dist HE initializer
z noise 100 128
fc units D[600], G[1200] D[512], G[1024]
image size 28x28 for cifar-10 32x32 for cifar-10
Optimizer SGD Adam
LR 2e-2 8e-4
LR Decay exponential decay None
momentum .5 to .8 None

Momentum Increasing by 8e-4.
Learning Rate : 2e-2 factor = 1 + 4e-5
Normal Distribution Initializer : (µ = 0, σ = 0.02)
HE Initializer parameters : (factor = 1, FAN_AVG, uniform)
