Special Issue Information

Dear Colleagues,

The brain–computer interface (BCI) aims to establish real-time, bidirectional connections between the brain and artificial devices. It is multidisciplinary, encompassing fields such as computer science and neuroscience. Advanced BCI provides new insights into brain functions, leading to improved treatments related to sleep, as well as for neural diseases such as paralysis, epilepsy, and Parkinson's disease. BCI has broad applications and continues to drive new discoveries in the field of medicine, education, entertainment, and marketing.

This Special Issue focuses on the field of the brain–computer interface and its technologies as well as applications. It includes a mix of original research papers, review articles on cutting-edge progress, and perspectives on challenges and future directions. The focus is interdisciplinary research combining computer science, neuroscience, medical and engineering expertise.

Topics of interest include, but are not limited to:

  • Neural signals encoding and decoding;
  • Neural signal processing algorithm;
  • Robotics based on BCI;
  • Clinical BCI;
  • Bio-sensors and bio-actuators;
  • BCI for education;
  • BCI for entertainment;
  • Commercial BCI.

Most BCI systems used in neurorehabilitation detect EEG features indicating motor intent based on machine learning, focusing on repetitive movements, such as limb flexion and extension. These machine learning methods require large datasets and are time consuming, making them unsuitable for same-day rehabilitation training following EEG measurements. Therefore, we propose a BMI system based on fuzzy inference that bypasses the need for specific EEG features, introducing an algorithm that allows patients to progress from measurement to training within a few hours. Additionally, we explored the integration of electromyography (EMG) with conventional EEG-based motor intention estimation to capture continuous movements, which is essential for advanced motor function training, such as skill improvement. In this study, we developed an algorithm that detects the initial movement via EEG and switches to EMG for subsequent movements. This approach ensures real-time responsiveness and effective handling of continuous movements. Herein, we report the results of this study. Full article

In the evolving field of Brain–Computer Interfaces (BCIs), accurately classifying Electroencephalography (EEG) signals for Motor Imagery (MI) tasks is challenging. We introduce the Correlation-Optimized Weighted Stacking Ensemble (COWSE) model, an innovative ensemble learning framework designed to improve MI EEG signal classification. The COWSE model integrates sixteen machine learning classifiers through a weighted stacking approach, optimizing performance by balancing the strengths and weaknesses of each classifier based on error correlation analysis and performance metrics evaluation across benchmark datasets. The COWSE model’s development involves selecting base classifiers, dynamically assigning weights according to performance, and employing a meta-classifier trained on these weighted predictions. Testing on the BNCI2014-002 dataset, the COWSE model achieved classification accuracy exceeding 98.16%, marking a significant advancement in MI EEG classification. This study highlights the potential of integrating multiple machine learning classifiers to address the complex challenges of EEG signal classification. By achieving new benchmarks and showcasing enhanced classification capabilities, the COWSE model contributes significantly to BCI research, encouraging further exploration into advanced ensemble learning strategies.
