2014-08-11 Thread Sameer Tilak
Hi All, We are currently using Weka. I looked the the site and read briefly about experimental nature of Mahout on Spark. I was wondering how mu of Mahout's functionality is available currently? For example, I am interested in using random forest implementation. I wanted to check if I c
