Requirement

• Pytorch >= v0.2.0

Usage

Please place adamPre file in the local folder of your project. You can start using AdamPre optimizer by simply importing it and initializing it like any other optimizer in Pytorch.

from adamPre import AdamPre
optG = AdamPre(netG.parameters(), lr=0.001, betas=(0.9, 0.999))

Once initialized, please appropriately call optG.stepLookAhead() and optG.restoreStepLookAhead() to update network weights using prediction method and to restore back to non-prediction weights respectively.

Please see sample code for MoG to understand the minor details. This code also reproduces the result in Figure 8 of the paper. One can start training from the console as follow:

$python main.py --pdhgGLookAhead --cuda --outf results/ --manualSeed 6162 --plotLoss --plotRealData

Other Implementations

• PyTorch Implementation with other optimizers + sample experimental results on DCGAN network.
