QuanGCN: Noise-Adaptive Training for Robust Quantum Graph Convolutional Networks

no code implementations9 Nov 2022 Kaixiong Zhou, Zhenyu Zhang, Shengyuan Chen, Tianlong Chen, Xiao Huang, Zhangyang Wang, Xia Hu

Quantum neural networks (QNNs), an interdisciplinary field of quantum computing and machine learning, have attracted tremendous research interests due to the specific quantum advantages.

RSC: Accelerating Graph Neural Networks Training via Randomized Sparse Computations

no code implementations19 Oct 2022 Zirui Liu, Shengyuan Chen, Kaixiong Zhou, Daochen Zha, Xiao Huang, Xia Hu

To this end, we propose Randomized Sparse Computation, which for the first time demonstrate the potential of training GNNs with approximated operations.

Theory and Applications of Financial Chaos Index

no code implementations5 Jan 2021 Masoud Ataei, Shengyuan Chen, Zijiang Yang, M. Reza Peyghami

We develop a new stock market index that captures the chaos existing in the market by measuring the mutual changes of asset prices.
