A 31 year old woman who was 11 weeks pregnant presented with sudden loss of vision in her left eye, which occurred after a typical migraine headache with a visual aura. However, the visual aura persisted and remained as a central scotoma.

CycleGANLoss ( cgan , l_A = 10 , l_B = 10 , l_idt = 0.5 , lsgan = TRUE ) Examples include WGAN [9], which replaces the cross entropy-based loss with the Wasserstein distance-based loss, LSGAN [45] that uses the least squares measure for the loss function, the VGG19 2020-05-18 In build_LSGAN_graph, we should define the loss function for the generator and the discriminator. Another difference is that we do not do weight clipping in LS-GAN, so clipped_D_parames is no longer needed. Instead, we use weight decay which is mathematically equivalent to … 2016-11-13 2017-04-27 During the process of training the proposed 3D a-LSGAN algorithm, the loss function. Discussion.

论文指出因为传统 GAN 辨别器 D 使用的是 sigmoid 函数,并且由于 sigmoid 函数饱和得十分迅速,所以即使是十分小的数据点 x,该函数也会迅速忽略样本 x 到 决策边界 w 的距离。. 这就意味着 sigmoid 函数本质上不会惩罚远离 决策边界 的样本 ,并且也 LS-GAN. 我们知道GAN分为generator(G)和discriminator(D),D实际上是一个分类器,用于分类输入图像是真实图像还是G产生的图像。. 这里说的误分类点就是D错误分类的数据。.

Instead of that LSGAN uses the least-squares loss function for the discriminator.

Least Squares GAN is similar to DCGAN but it is using different loss functions for Discriminator and for Generator, this adjustment allows increasing the stability of learning in comparison to…

Loss-Sensitive Generative Adversarial Network (LS-GAN). Speci cally, it trains a loss function to distinguish between real and fake samples by designated margins, while learning a generator alternately to produce realistic samples by minimizing their losses. The LS-GAN further regu-

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.

In this tutorial, you will discover how to develop a least squares generative adversarial network. After completing this tutorial, you will know: 2020-12-11 Loss-Sensitive Generative Adversarial Networks (LS-GAN) in torch, IJCV - maple-research-lab/lsgan 2018-08-23 2017-01-10 2017-05-01 To overcome such a problem, we propose in this paper the Least Squares Generative Adversarial Networks (LSGANs) which adopt the least squares loss function for the discriminator. We show that minimizing the objective function of LSGAN yields minimizing the Pearson X2 divergence.

The loss for real samples should be lower than the loss for fake samples. This allows the LSGAN to put a high focus on fake samples that have a really high margin. Like WGAN, LSGAN tries to restrict the domain of their function. 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.
