Logistic regression decision function
Witryna19 wrz 2024 · What is Logistic Regression? It is a classification algorithm that is applied in situations when the output variable is categorical. The goal of Logistic Regression is to discover a... WitrynaThe logistic function of odds is a sum of the weighted features. Each feature is simply multiplied by a weight and then added together inside the logistic function. So logistic regression treats each feature independently. This means that, unlike decision trees, logistic regression is unable to find interactions between features.
