Method for separation of positive sources from observations of measurements of signals detected from sensor, involves iteratively multiplying two matrices to achieve cone that minimizes optimization criterion

摘要

The method involves defining an initial cone in an orthant positive space of dimensions (31), where the cone contains a set of vectors representing observations. An optimization criterion (VW) is defined as a ratio of an absolute value of a determinant of a current matrix (W) on current product standards column vectors [w1-wn] of the current matrix, where the vectors form edges of the cone. Two matrices are iteratively multiplied (32) to achieve the cone that minimizes the optimization criterion defined as the ratio of the absolute value of the determinant of one of the multiplied matrices.
