Machine Learning – Can We Please Just Agree What This Means

Summary:  As a profession we do a pretty poor job of agreeing on good naming conventions for really important parts of our professional lives.  “Machine Learning” is just the most recent case in point.  It’s had a perfectly good definition for a very long time, but now the deep learning folks are trying to hijack the term.  Come on folks.  Let’s make up our minds.

Data or Algorithms – Which is More Important?

Summary:  Which is more important, the data or the algorithms?  This chicken and egg question led me to realize that it’s the data, and specifically the way we store and process the data that has dominated data science over the last 10 years.  And it all leads back to Hadoop.

Have You Heard About Unsupervised Decision Trees

Summary: Unless you’re involved in anomaly detection you may never have heard of Unsupervised Decision Trees.  It’s a very interesting approach to decision trees that on the surface doesn’t sound possible but in practice is the backbone of modern intrusion detection.

 

I was at a presentation recently that focused on stream processing but the use case presented was about anomaly detection.  When they started talking about unsupervised decision trees my…
