Clasificación aprendiz App

Entrenar, validar y afinar interactivamente modelos de clasificación

Elige entre varios algoritmos para entrenar y validar modelos de clasificación para problemas binarios o multiclase. Después de entrenar varios modelos, compare sus errores de validación de lado a lado y, a continuación, elija el mejor modelo. Para ayudarle a decidir qué algoritmo utilizar, consulte Train Classification Models in Classification Learner App.

Train Classification Models in Classification Learner App

Workflow for training, comparing and improving classification models, including automated, manual, and parallel training.

Select Data and Validation for Classification Problem

Import data into Classification Learner from the workspace or files, find example data sets, and choose cross-validation or holdout validation options.

Choose Classifier Options

In Classification Learner, automatically train a selection of models, or compare and tune options in decision trees, discriminant analysis, support vector machines, logistic regression, nearest neighbors, and ensembles.

Feature Selection and Feature Transformation Using Classification Learner App

Identify useful predictors using plots, manually select features to include, and transform features using PCA in Classification Learner.

Assess Classifier Performance in Classification Learner

Compare model accuracy scores, visualize results by plotting class predictions, and check performance per class in the Confusion Matrix.

Export Classification Model to Predict New Data

After training In Classification Learner, export models to the workspace, generate MATLAB® code, or generate C code for prediction.
