Re: ALS predictALL not completing
So to be clear, you're trying to use the recommendProducts method of MatrixFactorizationModel? I don't see predictAll in 1.3.1 1.4.0 has a more efficient method to recommend products for all users (or vice versa): https://github.com/apache/spark/blob/v1.4.0/mllib/src/main/scala/org/apache/spark/mllib/recommendation/MatrixFactorizationModel.scala#L152 On Tue, Jun 16, 2015 at 4:30 PM, Ayman Farahat ayman.fara...@yahoo.com wrote: This is 1.3.1 Ayman Farahat -- View my research on my SSRN Author page: http://ssrn.com/author=1594571 -- *From:* Nick Pentreath nick.pentre...@gmail.com *To:* user@spark.apache.org user@spark.apache.org *Sent:* Tuesday, June 16, 2015 4:23 AM *Subject:* Re: ALS predictALL not completing Which version of Spark are you using?
