public class ProblemIris
- extends ClassificationProblem
The classic Iris classification problem. Data set originates from
http://archive.ics.uci.edu/ml/datasets/Iris. Data file used comes from Weka:
http://www.cs.waikato.ac.nz/ml/weka/
The task is to classify the species of Iris flower given a set of four
numerical measurements.
