Underfitting & Overfitting - Explained

Underfitting and overfitting are some of the most common problems you encounter while constructing a statistical/machine learning model. It is therefore important to be able to recognize when either is occurring and what can be done to fix it. This is an extremely brief overview covering those topics, and, as always in machine learning, there is more to learn.

(Note: this author states that more data will not help with underfitting, however this is mainly true when you already have a bad model. If you are working with significantly less data (100s or 1000s of data points) then getting more data will make a bigger impact on underfitting.)
