WebSingular value decomposition (SVD) is not the same as reducing the dimensionality of the data. It is a method of decomposing a matrix into other matrices that has lots of wonderful properties which I won't go into here. For more on SVD, see the Wikipedia page. Reducing the dimensionality of your data is sometimes very useful. WebOct 11, 2016 · In practice TruncatedSVD is useful on large sparse datasets which cannot be centered without making the memory usage explode. numpy.linalg.svd and scipy.linalg.svd both rely on LAPACK _GESDD described here: http://www.netlib.org/lapack/lug/node32.html (divide and conquer driver)

Web2. Google brought me here too, and I found that the implementation of Scikit-learn library, a famous repository for data science in Python, uses SVDs with a small tweak to fit the data points and perform factor analysis. Hence the answer is a big YES you can use SVD. If you're keen with code implementation, I suggest you can read the Factor ... A non-negative real number σ is a singular value for M if and only if there exist unit-length vectors in K and in K such that The vectors and are called left-singular and right-singular vectors for σ, respectively.
