Author: Richard S. Forsyth Source: [UCI](https://archive.ics.uci.edu/ml/datasets/Zoo) - 5/15/1990 Please cite: Zoo database A simple database containing 17 Boolean-valued attributes describing animals. The "type" attribute appears to be the class attribute. Notes: * I find it unusual that there are 2 instances of "frog" and one of "girl"! * feature 'animal' is an identifier (though not unique) and should be ignored when modeling
