I know the abbreviations SVM(Support Vector Machines) and SVD(Singular Value Decomposition) and that both SVM, SVD are used in recommendation engines. In lay man's terms what is the difference be...

We plan to use Mahout for a movie recommendation system. And we also plan to use SVD for model building. When a new user comes we will require him/her to rate a certain number of movies (say 10). ...

I've been reading about using matrix factorization for collaborative filtering, but I can't seem to find an example that deals with adding a new user or item to the system, or having the user rate ...

My goal is to transfer a coordinate in perspective from a known rectangle (for example a 800 by 600 screen) to a quadrangle that is skewed/rotated. To do so i found this, which was extremely helpfu...

Does anyone know how to perform svd operation on a sparse matrix in python? It seems that there is no such functionality provided in scipy.sparse.linalg.

I have been working on latent semantic analysis lately. I have implemented it in java by making use of the Jama package. Here is the code: Matrix vtranspose ; a = new Matrix(termdoc); termd...

I'm trying to compile svdlibc on a 64 bit mac. Running the make file returns the error message: main.c:1: error: CPU you selected does not support x86-64 instruction set main.c:1: error: CPU you s...

I'm attempting to solve a set of equations of the form Ax = 0. A is known 6x6 matrix and I've written the below code using SVD to get the vector x which works to a certain extent. The answer is app...

Do yo know any example to use LAPACK To calculate SVD?

How does it actually reduce noise? Can you suggest some nice tutorials?
