资源描述

利用数据挖掘解决实际问题 1．实际需求某足球俱乐部想要在A城市建立集训基地，但由于足球运动的开展受气候影响较为严重，所以A城市的气候是否适合展开足球训练，首先要分析A城市的天气状况，满足以下3种情况的则为适宜开展足球训练。・阴天・雨天and微风・晴天and湿度正常 2．挖掘任务根据A城市最近半年的气候样本，对其各天气属性做分类挖掘。 3．具体采用挖掘算法及来源采用的是分类挖掘中的ID3算法，代码来源于weka的开源代码库 4．数据来源及挖掘结果【数据源】根据教材48页表3.1的气候训练样本集，对其进行修改后做成了如下的数据： @relation weather.halfyear @attribute outlook {sunny, overcast, rainy}//天气状况 @attribute temperature {hot, mild, cool}//温度信息 @attribute humidity {high, normal}//湿度信息 @attribute windy {TRUE, FALSE}//风力状况 @attribute play {yes, no}//是否适合足球训练 @data sunny,hot,high,FALSE,no sunny,hot,high,TRUE,no
