[SYSTEMDS-2792] Sparse Overlapping Matrix This commit change the Overlapping matrices to enable selectivity in which columns to overlap together, and furthermore for sparse right hand side matrices improve performance scaling in the sparsity of rows. Furthermore this commit also strives towards isolating functionality in the compressed matrix, such that the APIs used for individual features and functions are clearer for extensions.
Overview: SystemDS is a versatile system for the end-to-end data science lifecycle from data integration, cleaning, and feature engineering, over efficient, local and distributed ML model training, to deployment and serving. To this end, we aim to provide a stack of declarative languages with R-like syntax for (1) the different tasks of the data-science lifecycle, and (2) users with different expertise. These high-level scripts are compiled into hybrid execution plans of local, in-memory CPU and GPU operations, as well as distributed operations on Apache Spark. In contrast to existing systems - that either provide homogeneous tensors or 2D Datasets - and in order to serve the entire data science lifecycle, the underlying data model are DataTensors, i.e., tensors (multi-dimensional arrays) whose first dimension may have a heterogeneous and nested schema.
