问题如下:

The target variable for the labelled training data to be used in Step 3 is most likely which one of the following?

选项:

A.

A continuous target variable

B.

A categorical target variable

C.

An ordinal target variable.

解释:

B is correct. To predict which stocks are likely to become acquisition targets, the ML model would need to be trained on categorical labelled data having the following two categories: “0” for “not acquisition target”, and “1” for “acquisition
target”.
A is incorrect, because the target variable is categorical, not continuous.
C is incorrect, because the target variable is categorical, not ordinal (i.e., 1st, 2nd, 3rd, etc.).


是否只要是贴标签,就是category?

同学你好,

可以确定的是一定不会是continuous。

但贴标签也可能是ordinal,虽然这种可能性比较小。

NO.PZ201512020300000505 这题感觉答案错误。实际操作肯定是选top5. 要不然每一组的判断标准全部不一样?为了选出5各结果而不断变换标准? 题目说use labeleta to train,证明是用已经贴了标签的数据 比如是否上市五年(是1、否0),是否20%国有控股(是1、否0)等等,最终评分(0-1). A.0.9 B.0.8 C0.7 .6 E0.5 F0.4 G0.3 abc入选。 按照之前的答疑 如果选出来发现符合条件的超过5个,那么要做的是改变收购条件,让符合条件的只有5个,而不是要去排序。 如果怎么选都选不出5个呢? 这个无法理解,望解惑,感谢!

关于这道题的B,C,如果选择了贴标签的categorictarget variable, 但是题目中说只选5个,如果贴了标签之后发现有5个以上符合收购条件,那不是还得排序选出最适合收购的top 5吗?为什么不需要排序呢?
