회귀 학습기 앱
다양한 알고리즘 중에서 회귀 모델을 훈련시키고 검증할 알고리즘을 선택할 수 있습니다. 여러 모델을 훈련시킨 후 검증 오차를 나란히 비교한 다음 최적의 모델을 선택합니다. 어떤 알고리즘을 사용할지 결정하는 데 도움이 필요하다면 Train Regression Models in Regression Learner App 항목을 참조하십시오.
다음 플로우 차트는 회귀 학습기 앱에서 회귀 모델을 훈련시키는 일반적인 워크플로를 보여줍니다.

- 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 statistics and visualize results.
- Export Regression Model to Predict New Data
After training in Regression Learner, export models to the workspace, 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.
