Poll: Rapidminer memory: how much RAM do you use?

THW_MarkTHW_Mark Member Posts: 11 Contributor II
I've been working with rapidminer for a couple of weeks now (for textmining purposes) and one of the issues i keep running into is memory. I'm using the 64 bit version at 4GB ram (which gives about 2GB to work with if not running too much other stuff). For my purposes this seems to be the bare minimum, with enough feature reductions and splitting some processes in several sub processes, it is only just doable.

Of course, more ram=better, but im very curious how much you all use for your applications.

    I'm using Rapidminer with 4GB ram (64bit). It gives between 2.4GB and 2.7GB to work.

    I think you might consider changing data management from double to float. You will lose some precision, but you will need less memory.
    Also, in the area of text mining, sparse data representation might be useful for data management. I have never used that feature in RapidMiner, but you might want to try that.
