I attended the O'Reilly Strata 2012 today (Tuesday). It was the day for workshops; the conference will officially start on Wednesday morning and will last two days.
It has been great so far and much bigger than I expected. The motto is "Making data Work" which comes so close to heart for all of us here I attended two workshops today. The first one was on "R" (the open source version) and "Revolution R" (the commercial version) presented by Revolution Analytics. It was a great review of the power of R in general as well as what the commercial version, Revolution R, can offer in statistical analysis and machine learning.
The second workshop was titled "The two most important algorithms in predictive modeling today". The speakers, Jeremy Howard and Mike Bowles, talked about two major machine learning approaches today: random forests and glmnet. It was a very exciting and interactive session with some hands-on as well as theoretical discussions (Mike Bowles is a former MIT professor).
Overall, so far it has been a very well-attended (sold out!) event. On the algorithmic side there is a lot of buzz around R. On the implementation side, you hear a lot of Hadoop and MapReduce. There are big company names around both as sponsors and presenters such as Microsoft, IBM, Netflix, EMC, LinkedIn, vmware, Oracle, Amazon, to name a few. Will post more updates soon!
