Data Show, I spoke with Soumith Chintala, AI research engineer at Facebook. Among his many research projects, Chintala was part of the team behind DCGAN (Deep Convolutional Generative Adversarial Networks), a widely cited paper that introduced a set of neural network architectures for unsupervised learning.

In 2014, Ian Goodfellow and his colleagues at the University of Montreal published a stunning paper introducing the world to GANs, or generative adversarial networks. Through an innovative combination of computational graphs and game theory they showed that, given enough modeling power, two models fighting against each other would be able to co-train through plain old backpropagation. The models p
1. The document discusses Wasserstein GAN (WGAN), a type of generative adversarial network (GAN) that uses the Wasserstein distance rather than Jensen-Shannon divergence. WGAN has improved stability during training over traditional GANs. 2. WGAN trains the discriminator/critic to estimate the Wasserstein distance between real and generated distributions rather than classify samples. The gradient o
