DT PERFORMANCE ON EXAMPLE DATA

• Fisher's iris plant problem: standard baseline database in pattern recognition
  
  
• Contain 150 samples, 3 types of iris plants described by sepal and petal length and width
  
  

  Iris Setosa	Iris Versicolor	Iris Virginica

  
  
• Setosa is linearly separable from Versicolor and Virginica and Versicolor and Virginica are not linearly separable
  
  
• Bayesian DT gives a closed-loop error of 0% and open-loop error of 6%
  
  
• Best error rate quoted on this data is 0% for closed-loop and 8% for open-loop
