WebOct 1, 2024 · De Leeuw [23] proposed an iterative method that at each step minimizes a simple convex function which majorizes the complex function. This approach is called “Scaling by MAjorizing a COmplicated Function” (SMACOF) and it was proved to perform significantly better with respect to other approaches [23], in terms of guarantees and rate … Web上述问题的求解就没有闭式解了，而是使用一种叫stress majorization 的优化方法，稍微看了一下，是采用了SMACOF算法（Scaling by MAjorizing a COmplicated Function），具体这里就不介绍了（我也没怎么仔细看）。 …
