WebDec 27, 2024 · When I use OneHotEncoder using column transformer on this dataset, it results in a compressed sparse row format. After encoding, I wanted to split the data using train_test_split but that showed this error: Singleton array array (<32561x105 sparse matrix of type '' with 394963 stored elements in Compressed Sparse … WebCoordinate, and Doubly-Compressed Sparse Row/Column (DCSR/DCSC). In this work, we use the CSR format in most cases, with CSC only being used in a single case to improve performance of the inner product. We use CSR format for storing the mask. The CSR (CSC) format uses three arrays to store a sparse matrix: an array containing row (column)

Evidently, this format is pretty memory-efficient. The list of rows only needs to be as long as the number of non-zero matrix rows; the rest are omitted. Likewise, each list of column data only needs to be as long as the number of non-zero elements on that row.
