Logistic regression is a method we can use to fit a regression model when the response variable is binary. Logistic regression uses a method known as maximum likelihood estimation to find an equation of the following form log p (X) (1-p (X)) 0 1X1 2X2 pXp where Xj The jth predictor variable.

It learns an optimal set of hyperparameters, which might be different for each specific decision tree, dataset, or regression method. The process of finding the optimal configuration is sometimes called tuning. The component supports the following method for finding the optimum settings for a model integrated train and tune. Logistic regression does not really have any critical hyperparameters to tune. Sometimes, you can see useful differences in performance or convergence with different.

Multinomial logistic regression is an extension of logistic regression that adds native support for multi-class classification problems. Logistic regression, by default, is limited to two-class classification problems. Some extensions like one-vs-rest can allow logistic regression to be used for multi-class classification problems, although they require that the classification problem first.
