Circadian Rhythm Evaluation Using Fuzzy Logic

Useful information about person's behavior and its changes provides the measurement of the physical activity of the monitored person in flat. The identified changes are cyclic with a period of approximately 24 hours - this is Circadian Rhythm of Activity, CAR. In the event that we correlate CAR with information about the type of room and activities envisaged in this room, we can define the circadian rhythm (CR). The CR evaluation is made by different mathematical and statistical procedures now. Such systems do not mostly have predictive character. This work uses for classification and prediction of significant circadian rhythms deviations diagnostic method - fuzzy expert system. This methodology allows quick and effective decision-making and it shows predictive ability to detect deviations of circadian rhythm.
