Summary

Wearable healthcare devices represent the fastest-growing Internet of Things (IoT) sector, with many automated services relying on ECG and EEG signals. Deep neural networks (DNNs) are the primary method for processing these signals, but their high computational, energy, and memory demands conflict with the tight constraints of wearable devices. This investigation explores deploying advanced DNN models for EEG signal analysis, specifically for detecting epileptic seizures, on resource-constrained wearables. The study examines the trade-off between accuracy and computational complexity when applying parameter quantization and electrode reduction methods. Findings indicate that these techniques can significantly reduce DNN complexity with minimal accuracy loss, revealing explicit trade-offs for adapting DNN-based online EEG analysis to wearable devices.

Key takeaway
