One of the most fun events at the annual RapidMiner Community Meeting and Conference (RCOMM) is the live data mining process design competition "Who Wants to be a Data Miner?" In this competition, participants must design RapidMiner processes for a given goal within a few minutes. The tasks are related to data mining and data analysis, but are rather uncommon. In fact, most of the challenges ask for things RapidMiner was never supposed to do.

In 2010, we had posted the winning processes immediately after the conference. This year we did not do so because the processes depend on input files which could not easily be attached to these processes on myExperiment. As of RapidMiner 5.1.11 we have a new way of handling files making it easier to link RapidMiner processes against data files on the Web (more on this in this blog to come soon). Therefore, all data files are uploaded to Rapid-I webspace now, and the processes are also on myExperiment bundled in a pack .

The 2011 challenges were quite fun and were dealing with Hobbits, Vodka, and our latest, brand new product: RapidDraw. The processes are quite instructive and are worth playing around with. With the RapidMiner Community Extension you can download the processes directly from myExperiment into RapidMiner (just search for RCOMM). Alternatively, view the pack description on myExperiment.
