In recent days, bots (Twitter bots, Telegram bots, etc) have become more popular than ever. Why is that? After all, a bot is just a CLI (command line interface) between some system and user.
In algorithms of binary classification I usually meet the terms “precision” and “recall.” I had a really hard time understanding their meaning on a basic level. In other words, how would I explain them to a five year-old? I finally found these definitions:
- Precision is how often our algorithm predicts class one and turns out to be right.
- Recall is how many objects of class one the algorithm has found at all.
