Description

When I set k larger then the numer of examples the AUC should be the same.

import orange, orngTest, orngStat

data = orange.ExampleTable('lenses.tab')
res = orngTest.crossValidation([orange.kNNLearner(k=50), orange.kNNLearner(k=500)], data)

print 'Number of examples:', len(data)
print 'AUC:', orngStat.AUC(res)

output:

Number of examples: 24
AUC: [0.8129032258064517, 0.31612903225806455]
