logistic classifier

In : classifier = LogisticRegression (solver='lbfgs',random_state=0) Once the classifier is created, you will feed your training data into the classifier so that it can tune its internal parameters and be ready for the predictions on your future data. To tune the classifier, we run the following statement −

logistic regression for machine learning

Logistic regression models the probability of the default class (e.g. the first class). For example, if we are modeling people’s sex as male or female from their height, then the first class could be male and the logistic regression model could be written as the probability of male given a …
