The heuristic analysis, some concepts and theorems of constrained optimization are employed, e. g., linear feasible direction ( lfd ), and then the proof is first provided for the uniqueness, i. e., maximum nongaussianity is the sufficient and necessary condition to independent source recovery. moreover, based on the conclusion of the uniqueness of maximum nongaussianity, the paper also proposes an alternative but straightforward approach to the proof for the well known “ one - bit - matching ” conjecture presented in multi - unit approaches
和基於啟發性分析等傳統方法和結論比較，文中引入了線性化可行方向（ linearfeasibledirection ， lfd ）等約束優化概念和理論，首次給出了基於峭度的最大非高斯估計的唯一性證明，指出最大非高斯估計是獨立源提取的充分和必要條件。
