Feature engineering

Just curious guys what type of feature engineering have you tried… I tried adding/deleting some features but didn’t make much improvement of the scores :grin:

Have you ever heard of:

  • Eccentricity
  • Semi-latus rectum



In my notebook, I hinted about some features with regards to the ellipse such as :

ellipse_area = 3.1451926 * df$double_major * df$double_minor / 2 # surface area of the clock


Have a look at this super rich wikipedia page:


Disclaimer: You might find some super useful features in there, or perhaps nothing, but hey, at least you will learn new stuff! :laughing:
