声波 2D 交错网格有限差分正演模拟算法pml衰减边界条件 、多炮

将求解偏微分方程和局部网格加密简单组合在了一起。用的方程是一个含有间断二次系数的椭圆型方程，在系数间断的位置，解会有一个弱间断。-Will solve the partial differential equations and local mesh refinement simple combinations together. Used equation is a quadratic coefficient of containing discontinuous elliptic equations, the location of discontinuity in the coefficient, there will be a weak solution of continuity.

它是知名好初始化可以改善的速度和准确性的解决方案 许多非负矩阵分解 (NMF) 算法 [56]。许多 NMF 算法很敏感 在 W 或 H 或两者的初始化。这是尤其如此的算法 包括这两个新的 ALS 算法，我们目前的交替最小二乘法 （ALS） 类型 [55] 纸。我们比较六个初始化程序 (两个标准和四新) 的结果对我们 ALS 算法。最后，我们讨论选择适当收敛准则的实际问题。
