Removal of Ocular Artifacts from Electroencephalo-Graph by Improving Variational Mode Decomposition
文献摘要:
Ocular artifacts in Electroencephalo-graphy (EEG) recordings lead to inaccurate results in signal analysis and process.Variational Mode Decom-position (VMD) is an adaptive and completely non-recursive signal processing method.There are two parameters in VMD that have a great influence on the result of signal decomposition.Thus,this paper studies a signal decomposition by improving VMD based on squirrel search algorithm (SSA).It's im-proved with abilities of global optimal guidance and opposition based learning.The original seasonal mon-itoring condition in SSA is modified.The feedback of whether the optimal solution is successfully updated is used to establish new seasonal monitoring conditions.Opposition-based learning is introduced to reposition the position of the population in this stage.It is ap-plied to optimize the important parameters of VMD.GOSSA-VMD model is established to remove ocular artifacts from EEG recording.We have verified the effectiveness of our proposal in a public dataset com-pared with other methods.The proposed method im-proves the SNR of the dataset from-2.03 to 2.30.
