Reducing Dimension of datasets and implementation [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

To reach the state of the art of dimension reduction I'd like to know if there开发者_开发知识库 is an implementation no matter if it is pseudocode, c, java, matlab... of several algorithms or if there is some project that has some of them implemented

for example I know that for PCA we can use matlab's svd() function... but a full script or something...

FastICA is a very good package for doing this sort of thing, and it's available in C++, R, Python, and MATLAB. I have used the matlab version of this package; it's simple to use and produces good output.
