Embedding Decomposition for Artifacts Removal in EEG Signals

1 code implementation2 Dec 2021 Junjie Yu, Chenyi Li, Kexin Lou, Chen Wei, Quanying Liu

DeepSeparator employs an encoder to extract and amplify the features in the raw EEG, a module called decomposer to extract the trend, detect and suppress artifact and a decoder to reconstruct the denoised signal.

Multi-objective optimization via evolutionary algorithm (MOVEA) for high-definition transcranial electrical stimulation of the human brain

1 code implementation10 Nov 2022 Mo Wang, Kexin Lou, Zeming Liu, Pengfei Wei, Quanying Liu

In this paper, we propose a general framework called multi-objective optimization via evolutionary algorithms (MOVEA) to address the non-convex optimization problem in designing TES strategies without predefined direction.

Perturbing a Neural Network to Infer Effective Connectivity: Evidence from Synthetic EEG Data

no code implementations19 Jul 2023 Peizhen Yang, Xinke Shen, Zongsheng Li, Zixiang Luo, Kexin Lou, Quanying Liu

Specifically, we trained neural networks (i. e., CNN, vanilla RNN, GRU, LSTM, and Transformer) to predict future EEG signals according to historical data and perturbed the networks' input to obtain effective connectivity (EC) between the perturbed EEG channel and the rest of the channels.

Advancing EEG/MEG Source Imaging with Geometric-Informed Basis Functions

no code implementations31 Jan 2024 Song Wang, Chen Wei, Kexin Lou, Dongfeng Gu, Quanying Liu

Here, we present a novel method which utilizes the Brain Geometric-informed Basis Functions (GBFs) as priors to enhance EEG/MEG source imaging.
