A Distributed Classification Procedure for Automatic Sleep Stage Scoring Based on Instantaneous Electroencephalogram Phase and Envelope Features
- Computer ScienceIEEE Transactions on Neural Systems and Rehabilitation Engineering
A novel set of EEG-based features containing the Shannon entropy of the instantaneous analytical form envelope and frequencies of the EEG are proposed for sleep stage scoring, using a distributed decision-tree classifier with binary K-nearest neighbor classifiers at each decision node.
