CUR matrix approximation is a technique used in data analysis, particularly for dimensionality reduction and low-rank approximation of large matrices. The primary goal of CUR approximation is to represent a given matrix \\( A \\) as the product of three smaller, more interpretable matrices: \\( C \\), \\( U \\), and \\( R \\).
