Subject Re: [DISCUSS] R-Interface to SystemML

Janardhan: I believe this is the R4ML repo: https://github.com/SparkTC/r4ml
. Arvind: please correct me if I am wrong.

Overall, having a R interface for SystemML is an awesome idea. Since I am
not an R4ML expert, may be R4ML committers can comment on how they envision
"two code streams to work together".

Also, comparing the features of R4ML with that of our Python APIs will be
useful as it might make a stronger case for R4ML.

As an FYI, here are different ways Python users can use SystemML:
- Using MLContext to invoke DML script (
http://apache.github.io/systemml/beginners-guide-python#invoking-dmlpydml-scripts-using-mlcontext
 and
http://apache.github.io/systemml/spark-mlcontext-programming-guide.html)
- Python algorithms wrappers  (
http://apache.github.io/systemml/beginners-guide-python#invoke-systemmls-algorithms
)
- (not important for R4ML discussion): Python DSL (
http://apache.github.io/systemml/beginners-guide-python#matrix-operations)

Hi Arvind,

This is a great idea. One question: the R4ML generates any plan like the
SystemML with `DML` Or with providing some interface we leverage this
feature ?. Community effort in the sense of collaborative algorithm
implementation.(?)

Is this the Spark-R repo (
https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_rstudio_sparklyr&d=DwIGaQ&c=jf_iaSHvJObTbx-siA1ZOg&r=HzVC6v79boGYQrpc383_Kao_6a6SaOkZrfiSrYZVby0&m=uxG7P-4VuICwg6yatnAEX5JBdZ-PSwyvQzq5gwX1GL0&s=6VRs_J7zXj9jZEavEP8iNvVfISAjDJeM8wFL2sBnb0g&e=
  ) ?

Thanks,
Janardhan
