In my last post, Sparse Matrices For Efficient Machine Learning, I showcased methods and a workflow for converting an in-memory data matrix with lots of zero values into a sparse matrix with Scipy. It provides a better compression ratio with text data having large number of predefined words by using dictionaries. As a result, it provides a better compression algorithm and, in most cases, a smaller compressed file than it provides in.
