A Rickety Stairway to SQL Server Data Mining, Algorithm 5: The Neural Network Algorithm

by Steve Bolton

                Anyone who has been following this series of self-tutorials has probably grown accustomed to me adding some kind of disclaimer about my shortcomings as a data miner. These blog posts are designed to simultaneously give the most under-utilized part of SQL Server some badly needed free press,… Read more

A Rickety Stairway to SQL Server Data Mining, Algorithm 3: Decision Trees

by Steve Bolton 

                This series of self-tutorials is an elementary-level introduction to SQL Server Data Mining (SSDM), not the product of someone who’s done postgraduate work in statistics. Instead of being the last word on the subject, it is a little more like a child learning to speak its first… Read more

A Rickety Stairway to SQL Server Data Mining, Algorithm 1: Not-So-Naïve Bayes

            Thankfully, the simplest of SQL Server’s algorithms is not quite as naïve about data mining as I am.
            As mentioned in my last post, I had to delay my article on the simplest of Microsoft’s data mining algorithms due to a number of factors, the worst of which turned out… Read more
