NO.PZ201512020300000505 问题如下 The target variable for the labelletraining ta to usein Step 3 is most likely whione of the following? A.A continuous target variable B.A categorictarget variable C.orntarget variable. B is correct. To prewhistocks are likely to become acquisition targets, the ML mol woulneeto traineon categoriclabelleta having the following two categories: “0” for “not acquisition target”, an“1” for “acquisitiontarget”.A is incorrect, because the target variable is categorical, not continuous.C is incorrect, because the target variable is categorical, not orn(i.e., 1st, 2n 3r etc.). B和C的区别不就是C的各类是有优先顺序的嘛 我觉得选C更容易满足Step3想要的结果

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？
