Summary: Matrix Inversion on BlockMatrix
Key: SPARK-23266
URL: https://issues.apache.org/jira/browse/SPARK-23266
Project: Spark
Issue Type: New Feature
Components: MLlib
Affects Versions: 2.2.1
Reporter: Chandan Misra
Matrix inversion is the basic building block for many other algorithms like
regression, classification, geostatistical analysis using ordinary kriging etc.
A simple Spark BlockMatrix based efficient distributed divide-and-conquer
algorithm can be implemented using only *6* multiplications in each recursion
level of the algorithm. The reference paper can be found in
