Some people are going around talking about data mining, predictive analytics, advanced analytics, machine learning (more...)

We had a requirement in which the a column had either pure numbers such as 123 or pure alphabets such as QWED. The requirement was to display 'Y' in a column if the value was a number and display 'N' if it was a character string. While we can anyways have a case statement for each of the numbers i.e. 1,2,3,4,5,6,7,8,9,0, I found an easy way out by using the ASCII function.
The issue that has plagued a number of Essbase customers over the years related to running out of available ports has finally been fixed!

I cut my teeth in Essbase working with that API way back in the mid-1990's, but the writing had been on the wall for some time. Microsoft stopped supporting VB years ago, so it was only a matter of time before this time would come. That being said, I (more...)
Hidden among the noise surrounding the big three of the Indian IT industry - TCS, Wipro, and Infosys - was a very interesting sliver of signal that points to possibly big changes on the horizon. Though Cognizant should be counted among these (more...)

When you are working on building classification models you will need some ways of measuring the effectiveness of each model that you will build. This measurement/evaluation is perform during the model build process.
Typically the model build process consists of 2 steps (I'm assuming all data preparation etc has been completed:
Build the model: During this step you will feed in a portion of your data set to the data mining algorithm. Typical this data (more...)
