Árboles de regresión

Árboles de decisión binarios para la regresión

Para crecer interactivamente un árbol de regresión, utilice la aplicación Estudiante de regresión. Para mayor flexibilidad, crezca un árbol de regresión usando fitrtree en la línea de comandos. Después de cultivar un árbol de regresión, prediga las respuestas pasando el árbol y los nuevos Datos predictores a predict.

Aplicaciones

Estudiante de regresiónTrain regression models to predict data using supervised machine learning

Temas

Train Regression Trees Using Regression Learner App

Create and compare regression trees, and export trained models to make predictions for new data.

Supervised Learning Workflow and Algorithms

Understand the steps for supervised learning and the characteristics of nonparametric classification and regression functions.

Decision Trees

Understand decision trees and how to fit them to data.

Growing Decision Trees

To grow decision trees, fitctree and fitrtree apply the standard CART algorithm by default to the training data.

View Decision Tree

Create and view a text or graphic description of a trained decision tree.

Improving Classification Trees and Regression Trees

Tune trees by setting name-value pair arguments in fitctree and fitrtree.

Prediction Using Classification and Regression Trees

Predict class labels or responses using trained classification and regression trees.

Predict Out-of-Sample Responses of Subtrees

Predict responses for new data using a trained regression tree, and then plot the results.
