Regression Learner App

Interactively train, validate, and tune regression models

Choose among various algorithms to train and validate regression models. After training multiple models, compare their validation errors side-by-side, and then choose the best model. To help you decide which algorithm to use, see Train Regression Models in Regression Learner App.

This flow chart shows a common workflow for training regression models in the Regression Learner app.

Workflow in the Regression Learner app. Step 1: Select data and validation. Step 2: Choose regression model options. Step 3: Train a regression model. Step 4: Assess the regression model performance. Step 5: Export the regression model.

If you want to run experiments using one of the models you trained in Regression Learner, you can export the model to the Experiment Manager app. For more information, see Export Model from Regression Learner to Experiment Manager.

Apps

Regression Learner	Train regression models to predict data using supervised machine learning

Topics

Common Workflow

Train Regression Models in Regression Learner App
Workflow for training, comparing and improving regression models, including automated, manual, and parallel training.
Select Data for Regression or Open Saved App Session
Import data into Regression Learner from the workspace or files, find example data sets, choose cross-validation or holdout validation options, and set aside data for testing. Alternatively, open a previously saved app session.
Choose Regression Model Options
In Regression Learner, automatically train a selection of models, or compare and tune options of linear regression models, regression trees, support vector machines, Gaussian process regression models, kernel approximation models, ensembles of regression trees, and regression neural networks.
Visualize and Assess Model Performance in Regression Learner
Compare model metrics and visualize results.
Export Regression Model to Predict New Data
After training in Regression Learner, export models to the workspace and Simulink^®, generate MATLAB^® code, generate C code for prediction, or export models for deployment to MATLAB Production Server™.
Train Regression Trees Using Regression Learner App
Create and compare regression trees, and export trained models to make predictions for new data.
Train Regression Neural Networks Using Regression Learner App
Create and compare regression neural networks, and export trained models to make predictions for new data.
Train Kernel Approximation Model Using Regression Learner App
Create and compare kernel approximation models, and export trained models to make predictions for new data.
Compare Linear Regression Models Using Regression Learner App
Create an efficiently trained linear regression model and then compare it to a linear regression model. Export the efficient linear regression model to make predictions on new data.
