Feature Engineering Tips

So what is feature engineering?  Fundamentally it is the most important part of data science.  Or of any analytic method, from the simplest to the most complex.  Features are the data variables you include in your model.  Or often more importantly, the data you leave out of your model.  Or how your data can be combined or 're-engineered' to make it most useful.  Often you do not know what data features you have, or can measure, or even exist at all.   So its a good idea to thoughtfully understand which are important.  DSC on engineering them, with link to a white paper.    by Patti Tillotson
