Explaining precision and recall – Andreas Klintberg – Medium

The first days and weeks of getting into NLP, I had a hard time grasping the concepts of precision, recall and F1-score. Accuracy is also a metric which is tied to these, as well as micro-precision and macro-precision. These metrics are important in general machine learning and deep learning as well. However one of my colleagues (Thanks Marci!) explained it in an excellent way in which I'd thought I'd share. Many of you have probably already seen this, but for me it was a revelation in its simplicity.
