Riassunto:Attention monitoring is essential in tasks requiring sustained cognitive focus. Electroencephalography (EEG) offers a portable, cost-effective, and non-invasive solution; however, its signal complexity requires advanced processing. This study aims to develop an accurate and efficient method for classifying attention using a minimal EEG setup suitable for wearable applications. We propose an optimized single-channel EEG approach that combines Recursive Feature Elimination (RFE) for feature selection with a customized eXtreme Gradient Boosting (cXGB) classifier. The use of a single EEG electrode enables compatibility with commercially available, user-friendly EEG headbands, making real-time attention monitoring feasible in daily life. Our findings show that the proposed cXGB model achieves 98.29% binary and 94.25% three-class classification accuracy under subject-wise cross-validation, outperforming previous multi-channel approaches by 3%. Furthermore, the optimized feature set reduces processing time, memory usage, and energy consumption on both high-end (Intel i9) and low-power (Raspberry Pi) devices. This work provides an efficient and scalable solution for real-time, individualized attention monitoring on wearable platforms.
