| RapidMiner: The eye of mining |
 |
| Written by Massoud Toussi | |||
 RapidMiner is a dual licence (community and enterprise editions) open-source data mining solution due to the combination of its leading-edge technologies and its functional range. Applications of RapidMiner cover a wide range of real-world data mining tasks. These are pretty words that RapidiMiner team have placed on their site. Yet we must test the software before blieve them: what I did for you here! I've installed on a laptop Centrino Duo with 1MB of RAM with Windows XP. The installation was done properly without warning or error. The graphical interface is beautiful and fits well in Windows environment (apparently it can also be installed on other systems, but the website did not explain what it meant by other systems). There is a very good and complete documentation. In short, while a free software, it is comparable to SPSS Clementin in its allure and its graphic presentation. Compared to its functional richness, it exceeds some of the most expensive data mining software. It combines the features offered by Weka and some incorporated by Yale (its progenitor). Among its friendly features, a menu which categorizes different statistical tests and data mining models in groups that are much like chapters of a good book on the subject. Its modular archituecture and the existence of more than 400 plugins already show its success. Negative aspects should also be considered: its user interface is quite uncommon and I had spent a few hours before being able touse it and have my early experiments. However, I think this is due to its original workflow, with which I was not used ot work. A second default, the level of manipulation of data files it is not yet to the point: I was forced several times to change the format of my data, because it could not import them. Finally, I congratulate the team and the community, and strongly recommend using the software.
