这是我数据集的一小部分:
@relation
@attribute ID {'1','2','3','4','5'}
@attribute is_Weekend {Saturday, Sunday}
@attribute Weekday {Monday, Tuesday, Wednesday, Thursday, Friday}
@attribute Leaving_Time {'07:00<=x<09:00','09:00<=x<12:30'}
@data
'1',??,,'09:00<=x<12:30'
'2',??,'09:00<=x<12:30'
'3',??,'07:00<=x<09:00'
'4',??,'09:00<=x<12:30'
'5',??,'09:00<=x<12:30'
如何在数据部分定义工作日和周末!?
答案 0 :(得分:0)
我不太确定你要做什么,因为你的属性定义有点令人困惑。 is_Weekend
yes
和no
的值不应该@data
'1',?,'Monday','09:00<=x<12:30'
'2',?,'Thursday','09:00<=x<12:30'
'3','Saturday',?,'07:00<=x<09:00'
'4',?,'Monday','09:00<=x<12:30'
'5','Sunday',?,'09:00<=x<12:30'
吗?因为现在,每个数据点都需要周末和工作日。
假设它们是您想要的,您可以设置不适合丢失的属性:
@relation
@attribute ID {'1','2','3','4','5'}
@attribute is_Weekend {yes, no}
@attribute Weekday {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday}
@attribute Leaving_Time {'07:00<=x<09:00','09:00<=x<12:30'}
@data
'1','no','Monday','09:00<=x<12:30'
'2','no','Thursday','09:00<=x<12:30'
'3','yes','Saturday','07:00<=x<09:00'
'4','no','Monday','09:00<=x<12:30'
'5','yes','Sunday','09:00<=x<12:30'
我宁愿这样做:
{{1}}
