The Oracle Data Mining group has two openings for talented software developers and machine learning experts. Take a look at these links (IRC1133401, IRC1143559) for more details. Marcoshttp://www.blogger.com/profile/14756167848125664628noreply@blogger.com0

The Oracle BIWA Summit 2008 is approaching  (December 2-3) . It will be held at Oracle World HQ, Redwood Shores, California. This is the second event of its kind. Last year's event was a great success and lots of fun (see details here ). This year's keynotes include Jeanne Harris (co-author of "Competing on Analytics") and Usama Fayyad (legendary data miner).  Here are some information and linksMarcoshttp://www.blogger.com/profile/14756167848125664628noreply@blogger.com0

For a long time I have thought that we needed data mining books written for developers. Most data mining books are written for business or data analysts. Given that, it was a pleasant surprise to read Programming Collective Intelligence: Building Smart Web 2.0 Applications by Toby Segaran. The book provides a good discussion on data mining concepts anchored with interesting examples. It also Marcoshttp://www.blogger.com/profile/14756167848125664628noreply@blogger.com3

I firmly believe that a major trend in applications is the incorporation of analytic-enabled functionality. Users want more than just reports or a replay of the past. Users want to have insights and their attention directed to key points. This is where analytics can make a big impact across all types of applications. Notice that I am not proposing exposing analytical capabilities (e.g., data Marcoshttp://www.blogger.com/profile/14756167848125664628noreply@blogger.com2

Recently someone asked me how to invert a matrix using the UTL_NLA PL/SQL package. This can be done by solving a system of linear equations AX = B like the ones I described in this post but setting B to the identity matrix. I thought that the question was interesting enough to deserve its own post. So I am replicating the answer here for those interested. The UTL_NLA package has many different Marcoshttp://www.blogger.com/profile/14756167848125664628noreply@blogger.com1

It is that time of the year again. In about a week I am going to be attending the KDD (Knowledge Discovery in Databases) 2008 conference (conference website) along with some other Oracle colleagues. KDD is one of the primary conferences on data mining. This year it will take place in Las Vegas, Nevada, from August 24 to 27. Oracle is a Gold sponsor for the event and will have again a large Marcoshttp://www.blogger.com/profile/14756167848125664628noreply@blogger.com0
