## Logistic classifier

class turicreate.logistic_classifier. LogisticClassifier (model_proxy) Logistic regression models a discrete target variable as a function of several feature variables. The logisticClassifier uses a discrete target variable y instead of a scalar. For each observation, the probability that y = 1 (instead of 0) is modeled as the logistic function

• Classification Algorithms - Logistic Regression

Logistic regression is a supervised learning classification algorithm used to predict the probability of a target variable. The nature of target or dependent variable is dichotomous, which means there would be only two possible classes. In simple words, the dependent variable is binary in nature having data coded as either 1 (stands for success

• Logistic Regression — Classification or Regression? | by

Sep 19, 2021 Logistic regression is emphatically not a classification algorithm on its own. It is only a classification algorithm in combination with a decision rule that makes dichotomous the predicted probabilities of the outcome. Logistic regression is a regression model because it estimates the probability of class membership as a multilinear function
