Logistic regression is suitable for fitting models to a binary target with a buy, don't buy type of value which can be coded as 1, and 0, respectively. Logistic regression can be used to classify, for example, whether or not a person will buy. It can also be used to predict the con...

3.2.2 Logistic regression Logistic regression is one popular binary classification model. Logistic regression is actually the simplest neural network model, which is also known as the perceptron. Next, let us explain logistic regression with a traffic example. Suppose we want to determine whether a ...
