Abstract:
1. A method for calculating a class-specific iterated subspace for a classification system utilized in a computing system comprising: collecting training data related to a signal of interest, said training data being in the specific class for the class-specific iterated subspace; applying a linear orthogonal transform to the collected training data resulting in transformed training data in at least one bin; calculating the magnitude-square of each bin of the transformed training data producing magnitude-squared bins; arranging the magnitude-squared bins as columns y in a matrix Y; selecting orthonormal starting vectors from said matrix Y; creating a J function using said selected orthonormal starting vectors; and iteratively maximizing a sum of the logarithm of said created J function by adjusting said orthonormal starting vectors to obtain the class-specific iterated subspace.
