Observations from Chaotic Analysis of Sleep EEGs

Chaotic analysis and modeling methods were applied to a small collection of healthy individuals' sleeping EEGs in order to establish whether a common representational space could be discovered for use in comparative analysis. Common challenges were encountered and dealt with in a practical manner. The methods used and the choices made in this effort are described herein. The authors observe and describe a common representation, obtained from a delay coordinate embedding, that should be usable for comparative analysis leading to clinical utility.
