Witryna13 kwi 2024 · Logistic regression is a supervised learning algorithm used for binary classification tasks, where the goal is to predict a binary outcome (either 0 or 1). It’s a linear algorithm that models the relationship between the dependent variable and one or more independent variables. Witryna29 wrz 2024 · Logistic Regression is a Machine Learning classification algorithm that is used to predict the probability of a categorical dependent variable. In logistic regression, the dependent variable is a binary variable that contains data coded as 1 (yes, success, etc.) or 0 (no, failure, etc.).
