Sparse matrices greatly help dealing with large matrices with a lot of missing data. Sparse matrix efficiently store data set with a lot sparsity in matrix. It offers a much smaller memory foot print to store and access than the full matrix. With SciPy’s Sparse module, one can directly use sparse matrix for common arithmetic […]

Introduction to Sparse Matrices in Python with SciPy
What is a Sparse Matrix? Imagine you have a two-dimensional data set with 10 rows and 10 columns such that each element contains a value. We can also call such data as matrix, in this example it is a dense 10 x 10 matrix. Now imagine, you have a 10 x 10 matrix with only […]
