Books on Data Mining

helf@rapid-i.com — Mon, 01 Oct 2012 00:00:00 +0100

The Rapid-I team keeps on mining and we excavated two great books for our users. The first one, Data Mining for the Masses by Matthew North, is a very practical book for beginners and intermediate data miners, whereas The Elements of Statistical Learning by Trevor Hastie, Robert Tibshirani and Jerome Friedman provides a deep insight into the mathematical models driving the heart of every data analysis. It is not really hot off the press, but has not lost its glamour since the release of t [...]

Solving Sudokus with RapidMiner

fischer@rapid-i.com — Wed, 05 Sep 2012 00:00:00 +0100

This year's RCOMM live data mining challenge, "Who wants to be a data miner?", was a tricky yet fun task for the competitors. The task was to (partially) solve a Sudoku puzzle with RapidMiner. The solution shows that you can achieve virtually any data analysis task you can think of only by using standard RapidMiner processes.

The input data set consisted of examples [...]

File Objects and POSTing to Web Services

fischer@rapid-i.com — Mon, 21 Nov 2011 00:00:00 +0100

As of RapidMiner 5.1.11, we have introduced a new kind of I/O-Object in RapidMiner: File Objects. File Objects are generated by opening local files, URLs, looping over directories or ZIP files, etc. They are then parsed by Read CSV or Read Excel and converted to an example set. All this was possible before, partly by using macros, but it is now much simpler and more flexible.

Foremost, however, it offers a new way of sending input data to a process exposed as a Web service in RapidA [...]

Who Wants to be a Data Miner? (RCOMM 2011)

fischer@rapid-i.com — Wed, 02 Nov 2011 00:00:00 +0100

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 [...]

RCOMM 2011 Review - Day 2

mierswa@rapid-i.com — Tue, 28 Jun 2011 00:00:00 +0100

The second day started with another invited talk, namely Matthias Reif of the Deutsche Forschungszentrum Künstliche Intelligenz (DFKI) talking about Towards Next-Generation Data Mining. Matthias has presented very interesting insights about new trends in data analysis, including the data-driven recommendation of classifiers and the prediction of classifier accuracy and resource consumption. He depicted the integration of those techniques into server-based solutions li [...]
