[SYSTEMDS-3772] Nary elementwise multiplication rewrite/runtime - new runtime operations and rewrite for nary mult similar to add - fixed bug in nary hop, where output value type was computed wrongfully in case of scalars with mixed value types - fixed bug in nary hop, where output is wrongfully set as scalar - clean up & fixed the aggregate ternary rewrite to also work nary mult & fixed the n* lineage issue - increased code coverage for rewrite ternary aggregate: colsum(A^3) Closes #2105.
Overview: SystemDS is an open source ML 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.
