Summary: Improve the training process in
mnist_lenet_distrib_sgd.dml
Key: SYSTEMML-1821
URL: https://issues.apache.org/jira/browse/SYSTEMML-1821
Project: SystemML
Issue Type: Improvement
Components: ParFor, Runtime
Affects Versions: SystemML 1.0
Reporter: Fei Hu
Assignee: Fei Hu
SystemML engine will export the intermediate matrixes into HDFS, which may
impair the performance of distributed model training. Therefore the unnecessary
intermediate matrixes need to be avoided, and instead we can directly use the
dimension index to compute the final batch matrix.
