Apache Mahout - Befitting of the name!!

Well, it was 7 days back that I posted my first elementary question to the Mahout user group, and today I was able to successfully test my first program. Being a first timer in (Java+Eclipse+Maven+Mahout) = JEMM, it me almost a month to get things running. I would like to thank kuba pawloch@interia.pl, Sean Owen and Julian Ortega for your support. 
  Well I dont think there would have been anyone as ignorant as myself with JEMM, as I could'nt find queries as basic as mine. But anyways now I have moved on, and hope to use Mahout on a more serious note. However if there are/will be anyone who has similar issues, I would like to simply share the issues I had with getting mahout running.

my experiments with NETFLIX problem.

Evolution has been the main defining quality in us humans right from the start. The doctrine of change being central to the universe given by Heraclitus, we can observe temporal dynamics in almost everything. The conception of 'Tool' during the stone age compared to that of today reflects the advancements we have suceeded in.

 My interest lies in the playing a small role towards modernizing The WEB aided with machine learning algorithms and of course computer/internet technologies. With the Web getting smarter and more proximate with us, I would love to be a part of Connected World.

 
This is the latest project I have been working on. The NETFLIX problem seems to have attracted a great of attention from data scientists world over. This is one problem which I have enjoyed solving the most. Berkant Savas has been supervising me who is great fun to work with. Initially my attempt was to model the temopral aspects involved in the NETFLIX data. The main article I was refering to is "Collaborative Filtering with Temporal Dynamics" by Yehuda Koren. Yehuda Koren was part of the team BellKor's Pragmatic Chaos which won the NETFLIX prize in September 2009.

 The concept of evolution applied to 'the way people concieve movies' is what I would like to emphasize and capitalize on.
