Venn diagram of the classification errors of the classification algorithms, by feature set. Results were obtained from the classification of 27,000 = 45 (test species) ×10 (repetitions) ×60 (30+,30-). Figures (a), (b), (c) and (d) illustrate that the number of instances simultaneously misclassified by two or three learning algorithms depends on the feature set
