CycleGAN loss function. The individual loss terms are also atrributes of this class that are accessed by fastai for recording during training.
The LSGAN can be implemented with a minor change to the output layer of the discriminator layer and the adoption of the least squares, or L2, loss function. In this tutorial, you will discover how to develop a least squares generative adversarial network.
In this tutorial, you will discover how to develop a least squares generative adversarial network. I’m currently using nn.BCELoss for my primary GAN loss (i.e. the real vs. fake loss), and a nn.CrossEntropyLoss for an additional multi-label classification loss. LSGAN uses nn.MSELoss instead, but that’s the only meaningful difference between it and other (e.g.

It may be the first visible sign of the disease. In fact, 40% of people say they had unexplained weight loss when they were first diagnosed with cancer.
GAN Least Squares Loss. GAN Least Squares Loss is a least squares loss function for generative adversarial networks. Minimizing this objective function is equivalent to minimizing the Pearson $\chi^ {2}$ divergence. The objective function (here for LSGAN) can be defined as: $$ \min_ {D}V_ {LS}\left (D\right) = \frac {1} {2}\mathbb {E}_ {\mathbf {x} \sim p_ {data}\left (\mathbf {x}\right)}\left [\left (D\left (\mathbf {x}\right) - b\right)^ {2}\right] + \frac {1} {2}\mathbb {E}_ {\mathbf {z
lsGAN. In recent times, Generative Adversarial Networks have demonstrated impressive performance for unsupervised tasks. In regular GAN, the discriminator uses cross-entropy loss function which sometimes leads to vanishing gradient problems.

Loss-Sensitive Generative Adversarial Networks (LS-GAN) in torch, IJCV - maple-research-lab/lsgan lsGAN. In recent times, Generative Adversarial Networks have demonstrated impressive performance for unsupervised tasks. In regular GAN, the discriminator uses cross-entropy loss function which sometimes leads to vanishing gradient problems. Instead of that lsGAN proposes to use the least-squares loss function for the discriminator.

Another difference is that we do not do weight clipping in LS-GAN, so clipped_D_parames is no longer needed.
