| 摘 要： | C4.5算法是从经典算法ID3中改进得来,算法的最初来源是信息熵,从中确定属性和类别之间相关性和确定性。通过对信息熵的解释,深刻说明和分析C4.5算法。并提出把C4.5算法应用于高校教师评价上,构造出决策树,从而进一步提高和完善了对高校教师评价的准确性。

| Abstract: | C4.5 algorithm is come from ID3 classic algorithm,the source of algorithm is comentropy and the correlativity and corelation between attribute and category are ascertained.By introducing to information thermal charge,this paper explains and analyzes the C4.5 algorithm.And it suggests that the C4.5 algorithm can be applied to high school teacher valuation,puts up the decision-making tree in order to improve and perfect the accuracy of the high school teacher valuation. |
