问题如下：
Which
of the following errors would most likely be a result of overfitting a machine
learning model?
选项：
A.
Inability to recognize relationships within the
training data
B.
A predictive model that treats true parameters as if
they are noise
C.
The discovery of unsubstantiated patterns that lead to
prediction errors
解释：
Overfitting a model can lead to
the discovery of unsubstantiated patterns that lead to prediction errors and
incorrect output forecasts.
A is incorrect. The inability to
recognize relationships within the training data most likely results from
underfitting the model.
B is incorrect. The
development of a predictive model that treats true parameters as if they are
noise is most likely a result of underfitting the model.
理解如果model太粗会出现B，但如果model过于细了，也会出现把正确的结果判断错的情况，比如将白天鹅判断为不是天鹅，为什么B一定错？
