weka之数据集学习

每次先选定数据集，才可以继续选择上方的分类、聚类等

观察数据集weather.nominal.arff

weather.numeric.arff

观察上面两组天气数据，区别在温度和湿度，离散的连续的

温度取最小值，最大值、平均值和标准差，湿度类似

玻璃数据集glass.arff

Weka数据集格式-ARFF

Weka处理的数据集通常是存放在一种叫ARFF格式的文件中的。那么，什么是ARFF呢？

以weather.nominal.arff数据集为例，完整的数据集如下表示：

@relation weather.symbolic@attribute outlook {sunny, overcast, rainy}
@attribute temperature {hot, mild, cool}
@attribute humidity {high, normal}
@attribute windy {TRUE, FALSE}
@attribute play {yes, no}@data
sunny,hot,high,FALSE,no
sunny,hot,high,TRUE,no
overcast,hot,high,FALSE,yes
rainy,mild,high,FALSE,yes
rainy,cool,normal,FALSE,yes
rainy,cool,normal,TRUE,no
overcast,cool,normal,TRUE,yes
sunny,mild,high,FALSE,no
sunny,cool,normal,FALSE,yes
rainy,mild,normal,FALSE,yes
sunny,mild,normal,TRUE,yes
overcast,mild,high,TRUE,yes
overcast,hot,normal,FALSE,yes
rainy,mild,high,TRUE,no

ARFF定义

ARFF全称是Attribute-Relation File Format，属性关系文件格式。ARFF文件是一种描述了一系列具有相同属性的实例的ASCII文本文件。

具体一点来说，就是数据集主要是有两部分组成，一部分是属性描述，一部分是数据。

属性描述的这一部分也叫头信息，一般是放在数据集开始，而数据部分叫数据信息，一般是跟在头信息的后面。

ARFF头信息

ARFF的头信息包含这个关系的名称，还有一系列属性以及它们的数据类型。

以weather.nominal.arff数据集为例，标准的数据集的头信息如下表示：

@relation weather.symbolic@attribute outlook {sunny, overcast, rainy}
@attribute temperature {hot, mild, cool}
@attribute humidity {high, normal}
@attribute windy {TRUE, FALSE}
@attribute play {yes, no}

以%开头的句子是ARFF文件的注释。

在ARFF文件中，注释通常都是以%开头的。另外@RELATION，@ATTRIBUTE，@DATA都是大小写不敏感的，都可以使用。

@RELATION声明

通常来说，@RELATION声明应该是在ARFF文件的第一行出现，前面注释啥的不算哈！

具体的格式如下：@RELATION <relation-name>，这里<relation-name>是一个字符串，表示这个关系的名称。如果这个字符串包含空格的话一定要记得加上空格，否则识别会出现问题的。另外对于名称也有要求，不要使用'{', '}', ','或者'%’开头，或者是在ASCII表中低于\u0021[!]的字符。

@ATTRIBUTE声明

@ATTRIBUTE声明主要是用来指定属性的数据名称和类型，具体的格式如下：@ATTRIBUTE <attribute-name> <data-type>，一般来说，<attribute-name>的要求和上面<relation-name>的要求是一样的，Weka支持的数据格式<data-type>主要有以下几种：

numeric
integer is treated as numeric
real is treated as numeric
< nominal-specification >
string
date [< date-format >]
relational for multi-instance data (for future use)

其它的几个估计大家挺好明白，而< nominal-specification >和date估计不太好明白，没关系，我们下面再讲。

Nominal属性

所谓的Nominal属性就是后面列举一系列的值，比如{,,…}，IRIS数据集的class属性就是这么定义的：@ATTRIBUTE class {Iris-setosa,Iris-versicolor,Iris-virginica}。

date属性

date属性的定义比较特殊，因为它还涉及到一个格式的问题，所以我们需要指定相关的格式：@ATTRIBUTE <attribute-name> date [<date-format>]。日期的格式是比较复杂的，比如yyyy-MM-dd或者是MM-dd-yyyy等等，因此需要指定。具体的例子如下：@ATTRIBUTE birthday DATE "yyyy-MM-dd HH:mm:ss"对应的可参考的数据集如下：

@RELATION Timestamps@ATTRIBUTE timestamp DATE "yyyy-MM-dd HH:mm:ss"@DATA
"2001-04-03 12:12:12"
"2001-05-03 12:59:55"

ARFF数据信息

ARFF的数据信息主要是一系列的以,分隔的数据，并且开头的注解是@DATA，还是以weather.nominal.arff数据集为例，它的标准数据信息如下表示：

@data
sunny,hot,high,FALSE,no
sunny,hot,high,TRUE,no
overcast,hot,high,FALSE,yes
rainy,mild,high,FALSE,yes
rainy,cool,normal,FALSE,yes
rainy,cool,normal,TRUE,no
overcast,cool,normal,TRUE,yes
sunny,mild,high,FALSE,no
sunny,cool,normal,FALSE,yes
rainy,mild,normal,FALSE,yes
sunny,mild,normal,TRUE,yes
overcast,mild,high,TRUE,yes
overcast,hot,normal,FALSE,yes
rainy,mild,high,TRUE,no

@DATA声明

ARFF文件的数据部分都是跟在@DATA声明后面的。关于数据部分没有什么过多注意的地方，主要是注意数据缺失的情况，比如

@DATA
4.4,?,1.5,?,Iris-setosa

注：
有时数据中有数据比较稀疏，或者要使用one-hot编码时，可能会采用另一种方法记录数据data，如下图所示：

第一列代表第几个属性（从0开始），第二列代表对应的属性值。如果该属性不在.arff文件中则默认其属性值为0！（注意不是缺失值）

%       In determining whether the glass was a type of "float" glass or not,
%       the following results were obtained (# incorrect answers):
