Weka is<br>the most well-known data mining library. It is written in Java<br><a href="http://www.cs.waikato.ac.nz/ml/weka/">http://www.cs.waikato.ac.nz/ml/weka/</a>.<br>I consider this software extremely useful and it would add numerous<br>capabilities to Kepler, like R did! Weka includes: data sources,<br>Datasinks, filters, classifiers, clusterers, associations, evaluation<br>and visualization tools! to sum up, It is another piece of jewellery<br>like kepler!<br><br>Well, there several ways to do that:<br>(1) Using the RWeka project.<br><a href="http://cran.r-project.org/web/packages/RWeka/index.html">http://cran.r-project.org/web/packages/RWeka/index.html</a><br>Then the Weka algorithms can be called like R commands in the R<br>console actor of Kepler. However it doesn't seem the more powerful way<br>since Weka algorithms are also designed to run under a workflow<br>environment (KnowledgeFlow environment).<br><br>(2) Fully integrated: each Weka algorithm is converted to a Kepler<br>actor. Here comes my advice request. Which is the more efficient way<br>to undertake that process? Weka is open source software issued under<br>the GNU General Public License. So, java and class files for each<br>algorithm are completely available. Since I'm not a computer scientist<br>the only idea that comes to my mind is to embed/add the Weka java code<br>into the standard anatomy of a java Kepler actor code (ports,<br>parameters, action methods ...). Definitely this is a very tedious and<br>never ending task (it has to be done individually for each algorithm).<br>An ideas how to tackle that? Anyone can envisage a faster and more<br>systematic alternative?<br><br>Best wishes,<br><br>Josep Maria,<br><br><br>---------------------------------------------<br>Josep Maria Campanera Alsina<br>Juan de la Cierva Researcher<br>Departament de Fisicoquímica<br>Facultat de Farmàcia<br>Avgda Joan XXIII, s/n<br>08028 Barcelona · Catalonia · Spain<br>Tel: +34 93 4035988<br>Fax: +34 93 4035987<br>campanera@ub.edu<br>--------------------------------------------<br>_______________________________________________<br>Kepler-users mailing list<br>Kepler-users@ecoinformatics.org<br>http://mercury.nceas.ucsb.edu/ecoinformatics/mailman/listinfo/kepler-users<br></blockquote></div><br></div></body></html>
