原来train了一个model，但是早期的客户群credit score比较低，
现在新的客户群credit score有所提高，
问怎么判断什么时候原来train的model就不再适用，需要重新建一个新的model了
这题回答的不好，请问应该怎么考虑？ | s****h

which means you always think about adding new features/inputs to the
model
2. the evaluation, mean, SSE, or sth similar are increasing.
which means you need to keep monitoring the model. |
