A novel channel reduction concept to enhance the classification of motor imagery tasks in brain-computer interface systems
October 2025 • Taslima Khanam, Siuly Siuly, Kabir Ahmad, Hua Wang
Electroencephalogram (EEG) signals play a critical role in advancing brain-computer interface (BCI) systems, particularly for detecting motor imagery (MI) movements. However, analysing large volume of EEG datasets faces some challenges due to redundant information, and performance degradation. Irrelevant channels introduce noise, which reduces accuracy and slows system performance. To address these issues, this study aims to develop a novel channel selection method to enhance EEG-based MI task performance in BCI a…
