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
和基于启发性分析等传统方法和结论比较,文中引入了线性化可行方向( linearfeasibledirection , lfd )等约束优化概念和理论,首次给出了基于峭度的最大非高斯估计的唯一性证明,指出最大非高斯估计是独立源提取的充分和必要条件。
