This chapter contains sections titled: Introduction Determinism: Does It Exist? Randomness: An Illusion? Randomness and Noise How Do Biological Systems Cope with or Use Randomness? Uncertainty Principle in Biology Stochastic Resonance in Biology How Do Scientists and Engineers Cope with Randomness and Noise? A Selection of Coping Approaches Global State-Space Principal Component Analysis Local State-Space Principal Component Analysis Applications Cardiovascular Signals: Observer of the Autonomic Cardiac Modulation Noise Reduction by Spatio-Temporal PCA Blind Source Separation of Noisy Mixtures Results Electroencephalogram: Spontaneous EEG and Evoked Potentials Speech Enhancement Proposed Subspace Approach Subspace Partitioning Results Conclusions References
