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.halfyearattribute 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,
