What are the other features, and why do you want to find their values? – Dawny33 – 2015-12-06T11:07:43.000



A good answer to this question has to rely on the specific dataset / domain.

The questions I would ask myself are (in this order):

  • Can I solve my classification task without those features? → Just remove those features
  • Do I know of a relationship between features I know and the (partially) missing feature? → Find hard rules to fill those missing ones
  • Otherwise: Train a classifier / regression model to fill those missing features
