First, we study the problem of two-sample testing, where we wish to determine whether (and how) two different datasets meaningfully differ. We then study this framework in the setting of training generative models, such as generative adversarial networks (GANs), which learn to sample from complex distributions such as those of natural images.<br><br>The distances used are defined in terms of kernels, but we parameterise these kernels as deep networks for flexibility. This combination gives both theoretical and practical benefits over staying purely in either framework, and we obtain state-of-the-art results for unsupervised image generation on CelebA and ImageNet with our novel Scaled MMD GAN. <br></div><div style="font-size:small"><br></div><div style="font-size:small"><br></div><div style="font-size:small"><b>Host:</b> <a href="mailto:klivescu" target="_blank">Karen Livescu</a></div><div style="font-size:small"><br></div><div style="font-size:small"><br></div><div style="font-size:small"><br></div><div><div dir="ltr" class="gmail-m_1372530490503599919gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><font face="arial, helvetica, sans-serif">Mary C.
