摘要
根据实际需要,研究了一种基于信息增益的决策树构造算法,并将其应用到桥隧群应急决策系统中。数据测试表明,该算法具有较好的准确性。
In accordance with the actual needs, this paper studies a decision tree construction algorithm based on information gain and applies it in emergency decision system of bridge-tunnel groups. Test of data shows that the algorithm has better accuracy.
