示例1: decisionTreeLearning
# 需要导入模块: from TreeNode import TreeNode [as 别名]
# 或者: from TreeNode.TreeNode import addSubtree [as 别名]

if len(examples) == 0:
#if example list empty then return the majority value
#computed previously
return TreeNode(None, default)
elif checkIfSameClass(examples):
#if all examples same class then return the class
return TreeNode(None, examples[0].label)
elif len(attribs) == 0:
#if attributes empty then return majority value
return TreeNode(None, majorityValue(examples))
else:
bestAttrib = chooseAttribute(attribs, examples)
tree = TreeNode(bestAttrib)
majorityVal = majorityValue(examples)
#for each possible value of attribute
for attribVal in Attribute.getAttributes()[bestAttrib]:
filteredExamples = filterExamples(bestAttrib, attribVal, examples)
subTree = decisionTreeLearning(filteredExamples, \
filterAttributes(attribs, bestAttrib), majorityVal)
