In addition, we have created a large synthetic dataset, SynBRDF, which comprises a total of $500$K RGBD images rendered with a physically-based ray tracer under a variety of natural illumination, covering $5000$ materials and $5000$ shapes.
Unsupervised Image-to-Image Translation Networks
Unsupervised image-to-image translation aims at learning a joint distribution of images in different domains by using images from the marginal distributions in individual domains.

Deep Learning with Energy-efficient Binary Gradient Cameras
Power consumption is a critical factor for the deployment of embedded computer vision systems.
Pruning Convolutional Neural Networks for Resource Efficient Inference
We propose a new criterion based on Taylor expansion that approximates the change in the cost function induced by pruning network parameters.
Reinforcement Learning through Asynchronous Advantage Actor-Critic on a GPU
We introduce a hybrid CPU/GPU version of the Asynchronous Advantage Actor-Critic (A3C) algorithm, currently the state-of-the-art method in reinforcement learning for various gaming tasks.
