ICA seeks to minimize mutual information between projections.Independent component analysis finds a coordinate frame onto which the projection of the data has minimal temporal overlap. 
ICA is considered a linear decomposition alternative to principal component analysis (PCA). In PCA, the data is represented using perpendicular axes. ICA is not limited by this constraint 
ICA has been applied to domains such as:
noise separation 
ICA decompositions are best for sources linearly mixed in a recorded signal.
