Accuracy and stability of CUR decompositions with oversampling

Accuracy and stability of CUR decompositions with oversampling

This work investigates the accuracy and numerical stability of CUR decompositions with oversampling. The CUR decomposition approximates a matrix using a subset of columns and rows of the matrix. When the number of columns and the rows are the same, the CUR decomposition can become unstable and less...
