Presentation
Towards Accurate, Real-Time, and Energy-Efficient Attention Monitoring
Descriptionttention monitoring is crucial in various fields,
especially those involving prolonged periods of passive
observation. Electroencephalography (EEG) offers a cost-
effective, portable, and non-invasive solution; however,
the signal's intrinsic complexity necessitate advanced
analysis techniques. This research proposes a novel
approach for accurate attention classification. We selected
a representative channel and applied Recursive Feature
Elimination (RFE) to identify the most discriminating
features to enhance detection accuracy and minimize energy
consumption. On a public dataset, our optimized XGBoost
algorithm achieved 98.29% and 94.25% accuracy for binary
and three-class attention classification, respectively. The
refined feature set reduces execution time by 9%, memory
usage by 38%, and energy consumption by 8% on an Intel
i9-13900 platform. On a Raspberry Pi 5 the improvements
are 15%, 14%, and 14% respectively. By addressing these
challenges our approach facilitates adoption of wearable
devices for attention monitoring in various settings.
Index Terms—EEG signal, attention detection, machine
learning, feature engineering, wearable devices.
