Logistic regression is one of the most frequently used machine learning techniques for classification. However, though seemingly simple, understanding the actual mechanics of what is happening — odds ratio, log transformation, the sigmoid — and why these are used can be quite tricky. In this blog I will explain Logistic Regression under the hood, mostly intuitively, but at times with a teeny amount of maths.
