Hi Li, You may find the wiki useful, the following page describes the basic algorithms behind Mahout's implementation of Decision Forests:
https://cwiki.apache.org/MAHOUT/partial-implementation.html The following page describes how to launch the Breiman Example using the "sequential" implementation: https://cwiki.apache.org/MAHOUT/breiman-example.html The following page describes how to use the "partial" implementation to grow a decision forest and use it to classify new data: https://cwiki.apache.org/MAHOUT/partial-implementation.html For now, the "partial" implementation is the one that takes most advantage of Hadoop distributed capabilities. Although it has some limitations. Hopefully, I will be able to commit a new "full" implementation, later this year, that should handle larger datasets. --- En date de : Sam 29.1.11, Weiwei Li <[email protected]> a écrit : De: Weiwei Li <[email protected]> Objet: Is there any guidance documents in the Decision Forest? À: [email protected] Date: Samedi 29 janvier 2011, 14h26 Hi all, I have studied Decision Forest recently.But as a new man ,you know, there is a little difficult. In here, I want to know is there any guidance documents in the Decision Forest? Thank you!
