While we will not dive deep into explained variance score and R2 score in this lecture , one important point to remember is that, in general, metrics for regression are such that "higher is better"; that is, higher scores indicate better performance. When using error metrics, such as mean ...

evaluation metrics for regression: docs. Although there are many metrics, sometimes there might be a situation that you would like to monitor an evaluation metric that is not available, in such situation you can write your own custom evaluation metric. In this post, I will show you how to ...

This challenge is made even more difficult when there is a skew in the class distribution. The reason for this is that many of the standard metrics become unreliable or even misleading when classes are imbalanced, or severely imbalanced, such as 1:100 or 1:1000 ratio between a minority and...
