A Different Kind of Data Mining Automation

Posted by Heather Hinman on Thu, Mar 6, 2014 @ 03:18 AM

When your hear data mining automation, what do you usually think of? In general, the automation world has us thinking about the following process: you upload a dataset, select a multitude of modeling engines, then out comes the best model, and voilà, you're done. There are many positives in this scenario; you save time and it's generally reliable regarding the 'best model.' However, what about automating model building EXPERIMENTS? You ask: what do you mean by experiments?

The Do's and Don'ts of Data Mining [slideshare]

Posted by Heather Hinman on Thu, Feb 27, 2014 @ 11:11 AM

Since the dawn of data mining (beginning with Bayes Theorem in the 1700s), there have been many successes and failures, even by the top experts in the field. No matter what job function or industry you work in, it is generally agreed on that on-the-job training is a far better learning tool than any classroom lecture. Learning from our mistakes is one of the ways we move forward and accomplish our goals. The same goes for data mining practitioners and data scientists; hands-on experience (or lack thereof) results in victories and blunders that set the foundation for advancements in the field.

A Few Words On Predictive Accuracy From The Experts

Posted by Heather Hinman on Tue, Feb 25, 2014 @ 05:22 AM

Predictive accuracy is repeatedly cited by data scientists as one of the most important demands in modern data mining algorithms and software. It stands right along side the importance of model-building speed, missing value handling, and memory efficiency. So, if it is so important, how do the experts TEST the accuracy of their models?
