A Hybrid Brain-Computer Interface Using Motor Imagery and SSVEP Based on Convolutional Neural Network

no code implementations10 Dec 2022 Wenwei Luo, Wanguang Yin, Quanying Liu, Youzhi Qu

The key to electroencephalography (EEG)-based brain-computer interface (BCI) lies in neural decoding, and its accuracy can be improved by using hybrid BCI paradigms, that is, fusing multiple paradigms.

Explainable fMRI-based Brain Decoding via Spatial Temporal-pyramid Graph Convolutional Network

no code implementations8 Oct 2022 Ziyuan Ye, Youzhi Qu, Zhichao Liang, Mo Wang, Quanying Liu

The results show that STpGCN significantly improves brain decoding performance compared to competing baseline models; BrainNetX successfully annotates task-relevant brain regions.

Transfer learning to decode brain states reflecting the relationship between cognitive tasks

no code implementations7 Jun 2022 Youzhi Qu, Xinyao Jian, Wenxin Che, Penghui Du, Kai Fu, Quanying Liu

Transfer learning improves the performance of the target task by leveraging the data of a specific source task: the closer the relationship between the source and the target tasks, the greater the performance improvement by transfer learning.

Kuramoto model based analysis reveals oxytocin effects on brain network dynamics

no code implementations18 May 2021 Shuhan Zheng, Zhichao Liang, Youzhi Qu, Qingyuan Wu, Haiyan Wu, Quanying Liu

Here, we propose a physics-based framework of Kuramoto model to investigate oxytocin effects on the phase dynamic neural coupling in DMN and FPN.

HyperNTF: A Hypergraph Regularized Nonnegative Tensor Factorization for Dimensionality Reduction

no code implementations18 Jan 2021 Wanguang Yin, Youzhi Qu, Zhengming Ma, Quanying Liu

However, most of tensor decomposition methods are the linear feature extraction techniques, which are unable to reveal the nonlinear structure within high-dimensional data.
