Re: ALS run method versus ALS train versus ALS fit and transform

the new ALS()...run() form is underneath both of the first two. I am not sure what you mean by underneath, so basically the mllib ALS()...run() does the same thing as the mllib ALS train() ? On Wed, Jul 15, 2015 at 2:02 PM, Sean Owen so...@cloudera.com wrote: The first two examples are from

Re: ALS run method versus ALS train versus ALS fit and transform

Yes, just have a look at the method in the source code. It calls new ALS()run(). It's a convenience wrapper only. On Fri, Jul 17, 2015 at 4:59 PM, Carol McDonald cmcdon...@maprtech.com wrote: the new ALS()...run() form is underneath both of the first two. I am not sure what you mean by

Re: ALS run method versus ALS train versus ALS fit and transform

ALS run method versus ALS train versus ALS fit and transform

In the Spark mllib examples MovieLensALS.scala ALS run is used, however in the movie recommendation with mllib tutorial ALS train is used , What is the difference, when should you use one versus the other val model = new ALS() .setRank(params.rank)
