Logistic regression explained

Understanding logistic function is an important prerequisite to understanding logistic regression. So let's start by understanding what logistic function is. Logistic function is a type of sigmoid function that squishes values between 0 and 1. Although sigmoid function is an umbrella term for logistic and other functions, the term is often used to refer to logistic function. For instance, the logistic function is commonly known as sigmoid activation function in the context of neural networks.
