Sleep state classification

This project is based on an attempt to recognize various sleep states in the data recorded by CHIME home monitor. So far activity data captured by an accelerometrer located on a diaper, heart rate variabilty and respiratory variability have been used to classify sleep states. We are also looking into inreasing reliability of sleep state classification.
