Swapping Autoencoder for Deep Image Manipulation

NeurIPS 2020poster

Deep generative models have become increasingly effective at producing realistic images from randomly sampled seeds, but using such models for controllable manipulation of existing images remains challenging. We propose the Swapping Autoencoder, a deep model designed specifically for image manipulat…

Test-Time Training with Self-Supervision for Generalization under Distribution Shifts

ICML 2020poster

In this paper, we propose Test-Time Training, a general approach for improving the performance of predictive models when training and test data come from different distributions. We turn a single unlabeled test sample into a self-supervised learning problem, on which we update the model parameters b…

The Hessian Penalty: A Weak Prior for Unsupervised Disentanglement

ECCV 2020poster

Existing popular methods for disentanglement rely on hand-picked priors and complex encoder-based architectures. In this paper, we propose the Hessian Penalty, a simple regularization function that encourages the input Hessian of a function to be diagonal. Our method is completely model-agnostic and…

Time-Agnostic Prediction: Predicting Predictable Video Frames

ICLR 2019poster

Prediction is arguably one of the most basic functions of an intelligent system. In general, the problem of predicting events in the future or between two waypoints is exceedingly difficult. However, most phenomena naturally pass through relatively predictable bottlenecks---while we cannot predict t…

CyCADA: Cycle-Consistent Adversarial Domain Adaptation

ICML 2018oral

Domain adaptation is critical for success in new, unseen environments. Adversarial adaptation models have shown tremendous progress towards adapting to new environments by focusing either on discovering domain invariant representations or by mapping between unpaired image domains. While feature spac…

Investigating Human Priors for Playing Video Games

ICML 2018oral

What makes humans so good at solving seemingly complex video games? Unlike computers, humans bring in a great deal of prior knowledge about the world, enabling efficient decision making. This paper investigates the role of human priors for solving video games. Given a sample game, we conduct a serie…
