Personalized Federated Learning with First Order Model Optimization

3 code implementations ICLR 2021 Michael Zhang, Karan Sapra, Sanja Fidler, Serena Yeung, Jose M. Alvarez

While federated learning traditionally aims to train a single global model across decentralized local datasets, one model may not always be ideal for all participating clients.

World-Consistent Video-to-Video Synthesis

no code implementations ECCV 2020 Arun Mallya, Ting-Chun Wang, Karan Sapra, Ming-Yu Liu

This is because they lack knowledge of the 3D world being rendered and generate each frame only based on the past few frames.

Transposer: Universal Texture Synthesis Using Feature Maps as Transposed Convolution Filter

no code implementations14 Jul 2020 Guilin Liu, Rohan Taori, Ting-Chun Wang, Zhiding Yu, Shiqiu Liu, Fitsum A. Reda, Karan Sapra, Andrew Tao, Bryan Catanzaro

Specifically, we directly treat the whole encoded feature map of the input texture as transposed convolution filters and the features' self-similarity map, which captures the auto-correlation information, as input to the transposed convolution.

Hierarchical Multi-Scale Attention for Semantic Segmentation

8 code implementations21 May 2020 Andrew Tao, Karan Sapra, Bryan Catanzaro

Multi-scale inference is commonly used to improve the results of semantic segmentation.

Panoptic-based Image Synthesis

no code implementations CVPR 2020 Aysegul Dundar, Karan Sapra, Guilin Liu, Andrew Tao, Bryan Catanzaro

Conditional image synthesis for generating photorealistic images serves various applications for content editing to content generation.

Improving Semantic Segmentation via Video Propagation and Label Relaxation

5 code implementations CVPR 2019 Yi Zhu, Karan Sapra, Fitsum A. Reda, Kevin J. Shih, Shawn Newsam, Andrew Tao, Bryan Catanzaro

In this paper, we present a video prediction-based methodology to scale up training sets by synthesizing new training samples in order to improve the accuracy of semantic segmentation networks.

Partial Convolution based Padding

4 code implementations28 Nov 2018 Guilin Liu, Kevin J. Shih, Ting-Chun Wang, Fitsum A. Reda, Karan Sapra, Zhiding Yu, Andrew Tao, Bryan Catanzaro

In this paper, we present a simple yet effective padding scheme that can be used as a drop-in module for existing convolutional neural networks.
