For example, in multi-label logistic regression, a sample can be assigned to multiple different labels. Multi-label regression is the task of predicting multiple dependent variables within a single model. The Linear Regression component can solve these problems, as can most of the other regression components. Problems in which multiple inputs are used to predict a single numeric outcome are also called multivariate linear regression. Multiple linear regression involves two or more independent variables that contribute to a single dependent variable. This component supports simple regression. The classic regression problem involves a single independent variable and a dependent variable. However, the term "regression" can be interpreted loosely, and some types of regression provided in other tools are not supported. Linear regression also tends to work well on high-dimensional, sparse data sets lacking complexity.Īzure Machine Learning supports a variety of regression models, in addition to linear regression. Linear regression is still a good choice when you want a simple model for a basic predictive task. Simply put, regression refers to prediction of a numeric target. Linear regression is a common statistical method, which has been adopted in machine learning and enhanced with many new methods for fitting the line and measuring error. The trained model can then be used to make predictions. You use this component to define a linear regression method, and then train a model using a labeled dataset. Linear regression attempts to establish a linear relationship between one or more independent variables and a numeric outcome, or dependent variable. Use this component to create a linear regression model for use in a pipeline. This article describes a component in Azure Machine Learning designer.
