Dec 4, 2023 · Logistic Regression models the likelihood that an instance will belong to a particular class. It uses a linear equation to combine the input information and the sigmoid function to restrict predictions between 0 and 1. Gradient descent and other techniques are used to optimize the model’s coefficients to minimize the log loss.

Logitic regression is a nonlinear regression model used when the dependent variable (outcome) is binary (0 or 1). The binary value 1 is typically used to indicate that the event (or outcome desired) occured, whereas 0 is typically used to indicate the event did not occur.
