Loss-Sensitive Generative Adversarial Networks (LS-GAN) in torch, IJCV - maple-research-lab/lsgan


2020-12-11 · Loss function. Generally, an LSGAN aids generators in converting high-noise data to distributed low-noise data, but to preserve the image details and important information during the conversion process, another part of the loss function must be added to the generator loss function.

The following are 30 code examples for showing how to use torch.nn.MSELoss().These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. I am wondering that if the generator will oscillating during training using wgan loss or wgan-gp loss instead of lsgan loss because the wgan loss might be negative value. I replaced the lsgan loss with wgan/wgan-gp loss (the rest of parameters and model structures were same) for horse2zebra transfer mission and I found that the model using wgan/wgan-gp loss can not be trained: 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: LSGAN, or Least Squares GAN, is a type of generative adversarial network that adopts the least squares loss function for the discriminator. Minimizing the objective function of LSGAN yields minimizing the Pearson $\chi^{2}$ divergence.

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。.

Aiming at the problem of radar target recognition of High-Resolution Range Profile (HRRP) under low signal-to-noise ratio conditions, a recognition method based on the Constrained Naive Least-Squares Generative Adversarial Network (CN-LSGAN), Short-time Fourier Transform (STFT), and Convolutional Neural Network (CNN) is proposed. Combining the Least-Squares Generative Adversarial Network

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- Se hela listan på wiseodd.github.io To overcome such a prob- lem, we propose in this paper the Least Squares Genera- tive Adversarial Networks (LSGANs) which adopt the least squares loss function for the discriminator.

If you're among the many who want to lose some extra pounds, congratulations on deciding to make your health a priority. An abundance of supplements promote weight loss, making it hard to determin Losing weight can improve your health in numerous ways, but sometimes, even your best diet and exercise efforts may not be enough to reach the results you’re looking for. If that’s the case, you might consider exploring weight-loss surgery Losing a loved one to cancer can be a painful and difficult time. In this guide, we discuss the grieving process and offer tips that may help you cope with your loss.

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. After completing this tutorial, you will know:

Trong series GAN này mình đã giới thiệu về ý tưởng của mạng GAN, cấu trúc mạng GAN với thành phần là Generator và Discriminator, GAN loss function. Tuy nhiên GAN loss function không tốt, nó bị vanishing gradient khi train generator bài này sẽ tìm hiểu hàm LSGAN để giải quyết vấn đề trên.


2021年3月23日 LSGAN 的提出,是为了解决经典GAN的梯度失效问题,将sigmoid的loss换成least squares 可以更有效传递判别器的梯度。我们以DCGAN 为参考 

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.
