Comparative Study of Kurtosis-Based FastICA and RobustICA Using Spatial Smoothing Preprocessing

Independent Component Analysis (ICA) is expected to decompose the incident signals and detect each signal effectively and conveniently. ICA is a statistical technique utilizing only the property that incident signals are independent of each other. This paper discusses an improved method to introduce spatial smoothing preprocessing (SSP) into FastICA and RobustICA algorithms.
