UCI大数据库使用说明书

1、UCI数据库使用说明机器学习领域的UCI数据集使用说明此目录包含数据集和相关领域知识（后面以简短的列表形式进行的注释） 这些数据已经或能用于评价学习算法。每个数据文件（*data ）包含以“属性-值”对形式描述的很多个体样本的 记录。对应的*.info文件包含的大量的文档资料。（有些文件_generate_databases ；他们不包含*.data文件。）作为数据集和领域知识的补充，在utilities 目录里包含了一些在使用这一数据集时的有用资料。地址 /mlearn/MLRepository.html， 这里的UCI数据集可以看作是通过 web的

2、远程拷贝。作为选择，这些数据同样可以通过ftp 获得，ftp:/ .可是使用匿名登陆ftp 。可以在 pub/mach in e-lear nin g-databases目录中找到。UCI 一直都在寻找可加入的新数据，这些数据将被写入in comi ng子目录中 希望您能贡献您的数据，并提供相应的文档。谢谢一一贡献过程可以参考 DOC-REQUIREMENTS文件。目前，多数数据使用下面的格式：一个实例一行, 没有空格，属性值之间使用逗号“，”隔开，并且缺少的值使用问号“ ？”表示。并请在做出您的贡献后提醒一下站点管理员：ml-repositoryics.uci
