Unsupervised image-to-image translation is an inherently ill-posed problem. Recent methods based on deep encoder-decoder architectures have shown impressive results, but we show that they only succeed due to a strong locality bias, and they fail to learn very simple nonlocal transformations (e.g. mapping upside down faces to upright faces). When the locality bias is removed, the methods are too powerful and may fail to learn simple local transformations. In this paper we introduce linear… 

Encoding in Style: a StyleGAN Encoder for Image-to-Image Translation

We present a generic image-to-image translation framework, pixel2style2pixel (pSp). Our pSp framework is based on a novel encoder network that directly generates a series of style vectors which are


Classifiers trained using the proposed AdversarialAugment method in conjunction with prior methods improve upon the state-of-the-art on common image corruption benchmarks conducted in expectation on CIFAR-10-C and also improve worst-case performance against `p-norm bounded perturbations on both CIFar-10 and IMAGENET.

This work seeks to predict unseen data (and their labels) allowing us to tackle challenges s a non-constant data distribution in a proactive manner rather than detecting and reacting to already existing changes that might already have led to errors.

Defending Against Image Corruptions Through Adversarial Augmentations

This work proposes AdversarialAugment, a technique which optimizes the parameters of image-to-image models to generate adversarially corrupted augmented images and improves worst-case performance against `p-norm bounded perturbations on both CIFAR-10 and IMAGENET.

Improved Modeling of 3D Shapes with Multi-view Depth Maps

The quantitative evaluations show that the simple encoder-decoder framework is superior to existing depth map methods for reconstructing and synthesizing 3D objects and is competitive with other representations, such as point clouds, voxel grids, and implicit functions.

Spectral Geometric Matrix Completion

This work interprets the Deep Matrix Factorization model through the lens of spectral geometry, which allows it to incorporate explicit regularization without breaking the DMF structure, thus enjoying the best of both worlds.

An alternative generator architecture for generative adversarial networks is proposed, borrowing from style transfer literature, that improves the state-of-the-art in terms of traditional distribution quality metrics, leads to demonstrably better interpolation properties, and also better disentangles the latent factors of variation.
