Near-Linear Time and Fixed-Parameter Tractable Algorithms for Tensor Decompositions

no code implementations15 Jul 2022 Arvind V. Mahankali, David P. Woodruff, Ziyu Zhang

Our key technique is a method for obtaining subspace embeddings with a number of rows polynomial in $q$ for a matrix which is the flattening of a tensor train of $q$ tensors.

Using Deep Learning Sequence Models to Identify SARS-CoV-2 Divergence

no code implementations12 Nov 2021 Yanyi Ding, Zhiyi Kuang, Yuxin Pei, Jeff Tan, Ziyu Zhang, Joseph Konan

SARS-CoV-2 is an upper respiratory system RNA virus that has caused over 3 million deaths and infecting over 150 million worldwide as of May 2021.

Few-Data Guided Learning Upon End-to-End Point Cloud Network for 3D Face Recognition

no code implementations31 Mar 2021 Yi Yu, Feipeng Da, Ziyu Zhang

Without fine-tuning on the test set, the Rank-1 Recognition Rate (RR1) is achieved as follows: 98. 85% on FRGC v2. 0 dataset and 99. 33% on Bosphorus dataset, which proves the effectiveness and the potentiality of our method.

Generative Modeling using the Sliced Wasserstein Distance

1 code implementation CVPR 2018 Ishan Deshpande, Ziyu Zhang, Alexander Schwing

While this is particularly true for early GAN formulations, there has been significant empirically motivated and theoretically founded progress to improve stability, for instance, by using the Wasserstein distance rather than the Jenson-Shannon divergence.

Creativity: Generating Diverse Questions using Variational Autoencoders

no code implementations CVPR 2017 Unnat Jain, Ziyu Zhang, Alexander Schwing

Generating diverse questions for given images is an important task for computational education, entertainment and AI assistants.
