Hi Luciano and Henry, Currently there is a discussion regarding possibly integrating code from the R4ML project (https://github.com/SparkTC/r4ml) into SystemML. R4ML is an Apache-licensed open-source project and IBM owns the copyright ( https://github.com/SparkTC/r4ml/blob/master/R4ML/R/R4ML.R). L

Re: [DISCUSS] R-Interface to SystemML

2017-09-21 Thread Deron Eriksson
I agree with Niketan. An R interface definitely makes sense for SystemML. DML itself is based on R, so it's surprising we have Java/Scala/Python interfaces to SystemML but we don't have an R interface. Perhaps R4ML committers could supply a little more info? For instance: 1) Would they like to mer

Hi Janardhan, Thank you for working on #2 [SYSTEMML-1645]. It looks like there are around 30 algorithms in the scripts directory. To verify that each of these algorithms works with MLContext in a reproducible form through the creation of MLContext tests for each algorithm is an enormous undertaki

Could we add a "cut()" or "cutGraph()" function to DML for debugging that would cut the graph in a similar fashion as "if(1==1){}" and "while(false){}"? It might be a little more straightforward and explicit for users. Deron On Sun, Aug 6, 2017 at 3:42 PM, Matthias Boehm wrote: > Hi all, > > we

Auto format DML?

2017-08-03 Thread Deron Eriksson
Hi, I experimented with Atom's Beautify to see if I could automatically format DML using their R format. Since DML is quite similar to R, I found that making a few minor tweaks to DML made it possible to run DML scripts through the R formatter. DML vs R syntax differences (there may be more): 1)

Thank you Mike for bringing this up. To me, this definitely makes sense at the user (DML) level. For a Java-style pseudocode example, currently we require the user to do the following: int[][] m = int[][]{1,2,3,4}; int[][] n = m[0][0]; int x = (int) n; I feel the following would be more 'na
