I'm just wondering if anyone out there knows of a java implementation of singular value decomposition (SVD) for large sparse matrices? I need this implementation for latent semantic analysis (LSA). I tried the packages from UJMP and JAMA but they choke when the number of row >= 1000 and col >= 500. If anyone can point me to psuedocode or something out there, that would be greatly app
我只是想知道是否有人知道大型稀疏矩阵的奇异值分解（SVD）的Java实现？ 我需要执行潜在语义分析（LSA）。 我尝试了来自UJMP和JAMA的软件包，但当行数> = 1000和col> = 500时，它们会窒息。如果任何人都可以指向我的psuedocode或其他东西，那将不胜感激。 Wikipedia上有一系列Java数字图书馆。 NIST图书馆很不错，不幸的是它没有处理稀疏矩阵。 我对其他软件包不太熟悉。 你可以看看柯尔特; 它的质量也很高，并且
