Hi Kong,

I had the same question.  Have you heard any solution to the recommender engine problem? 

Any info you can share would be great.

Thanks

Kong,

I think we've to create R / Python algorithm and run it in H2O

You can do matrix completion using GLRM.  See this example: https://github.com/h2oai/h2o-3/blob/739ec856995d066ccecb8eb605ca9ef5a9d3baa6/h2o-r/demos/rdemo.glrm.movielens.medium.R

Hi Erin,

Where can i get the sample data used in the R code
pathToData <- h2o:::.h2o.locate("smalldata/demos/movielens_1m.zip") pathToMovies <- h2o:::.h2o.locate("smalldata/demos/movies.dat")

Hi,

Good question.  You can get the "smalldata" subfolder of H2O from S3 by doing the following:

git clone https://github.com/h2oai/h2o-3.git
cd h2o-3
./gradlew syncSmalldata

Also, this was recently added to our docs:
