Randomized LU Decomposition

Gil Shabat, Yaniv Shmueli, Yariv Aizenbud +1

We present a fast randomized algorithm that computes a low rank LU decomposition. Our algorithm uses random projections type techniques to efficiently compute a low rank approximat…

Missing Entries Matrix Approximation and Completion

Gil Shabat, Yaniv Shmueli, Amir Averbuch

We describe several algorithms for matrix completion and matrix approximation when only some of its entries are known. The approximation constraint can be any whose approximated so…
