"Association Rules hangs machine"
I am working on a text analysis project of news articles grabbed from the internet. I have been successful in extracting the content, preprocessing (tokenizing, filtering, transforming case etc) and generating a binary term occurrence exampleset. I followed Neil M's video and used Process documents from files, Numerical to Binomial and FP Growth. Using breakpoints, all these stages appear to be fine and run quickly. When I attempt to create Association rules, the machine runs and seems to hang, regardless of the memory allocated when I start java (I use the command line and for instance, assigned as follows:
java -Xmx12000m -jar rapidminer.jar. Right now, the program seems locked out (still calculating the rules at 13 minutes) and one CPU is at 100%. My dataset only has five documents in it and the rest of the process ran in 3 seconds or less on an 8 core Mac Pro. I noticed that the memory usage would increment and max out, regardless of how much I allocated (I have tried various lower and upper limits and read on a Weka site that one should not set both -Xms and -Xmx at the same time).
