问题如下:
Paul suggests the following
step which would be repeated every quarter.
Step 3 For each of
the 20 different groups, we use labeled data to train a model that will predict
the five stocks (in any given group) that are most likely to become acquisition
targets in the next one year.
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
A categorical target variable
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.).
老师,您好!
根据打了标签的数据训练AI模型,预测最可能的并购目标,我理解是对目标预测出一个概率啊,那应该是连续的才对啊。麻烦老师解释一下,谢谢!
