Distributed linear algebra algorithms

Definition

Distributed linear algebra algorithms are computational methods designed to perform linear algebra operations across multiple machines or processors, enabling the handling of large-scale data sets efficiently. These algorithms leverage parallel processing to execute matrix operations and vector calculations, significantly speeding up computations that would be too resource-intensive for a single machine. This is particularly important in data science, where big data is prevalent and requires advanced methods for analysis and processing.
