helf@rapid-i.com — Mon, 23 Jan 2012 00:00:00 +0100

After quite some time of hard development, the Rapid-I team is proud to announce the birth of its latest baby: a brand new plot component presenting you a shiny, powerful and flexible visualization of your data and process results.

The new plotters support bar charts, area charts, scatter and series plots with a single configuration. Instead of preselecting a diagram type from a list of templates the new plotters allow you to freely choose the visualization type of each attribute. You can plot [...]

Practical Data Mining Lectures from Simafore

mierswa@rapid-i.com — Thu, 19 Jan 2012 00:00:00 +0100

From time to time, we post articles about how specific analysis methods work and how those methods and approaches can be done with RapidMiner.
Our colleagues from Simafore, an US-based consultancy company for advanced analytics, also follow this approach and describe many applications of data mining in real-world scenarios together with practical examples done with RapidMiner.

So I thought their blog might be interesting to you, especially for those of you not already familiar wit [...]

The Intelligent Discovery Assistant

fischer@rapid-i.com — Mon, 09 Jan 2012 00:00:00 +0100

Imagine all you would have to do for creating a data mining process was to select a data set and specify what you want to do with the data, e.g. predictive modelling. Wouldn't that save a lot of work?

Within the research project "e-LICO", funded by the EU within the 7th Framework Programme, the Intelligent Discovery Assistant (IDA) was developed, and it does precisely that. It comes with its own perspective (marked with the silhouette of a friendly butler) that conta [...]

It was quite calm in the Rapid-I blog during the last weeks, sorry for that... It's vacation time and those of us who have to stay are quite busy these days.

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 [...]

RCOMM 2011 Review - Day 1

mierswa@rapid-i.com — Mon, 27 Jun 2011 00:00:00 +0100

Directly after the RCOMM, I was on vacation and therefore did not get the time to write something about RCOMM 2011 until now, sorry. Here is a review for those who visited the conference or who want to learn more about what happened in Dublin a couple of weeks ago.

RCOMM 2011 was again a huge success! It was great to meet many users of RapidMiner and RapidAnalytics again after the first community meeting in Dortmund last year. Many visitors from R [...]

Rapid-I Marketplace Launched

fischer@rapid-i.com — Mon, 30 May 2011 00:00:00 +0100

Over the years, many of you have been developing new RapidMiner Extensions dedicated to a broad set of topics. Whereas these extensions are easy to install in RapidMiner - just download and place them in the plugins folder - the hard part is to find them in the vastness that is the Internet. Extensions made by ourselves at Rapid-I, on the other hand, are distributed by the update server making them searchable and installable directly inside RapidMiner.

We thought that this was a b [...]
