Los métodos más utilizados para modelar aprendizaje automático son:
SVM: Support Vector Machine o Máquina de Vectores de Soporte. Hay varios subtipos: Lineal(svmLineal), Radial (svmRadial), Polinómico (svmPoly), etc.
Árbol de Decisión: rpart
Redes Neuronales: nnet
Random Forest o Bosques Aleatorios: rf
Checar accuracy para elegir el mejor modelo
1. Modelo con el método svmLineal
modelo <- train(Class~ ., data = entrenamiento, method = "svmLinear", preProcess = c ("scale", "center"), trControl = trainControl(method ="cv", number=10), tuneGrid = data.frame(C = 1)) #Cuando es svmLinear
resultado_entrenamiento <- predict(modelo, entrenamiento)
resultado_prueba <- predict(modelo, prueba)
#Matriz de Confusión
mcre <- confusionMatrix(resultado_entrenamiento, entrenamiento$Class)

# Distintos tipos de Métodos para Modelar
Los métodos más utilizados para modelar aprendizaje automático son:

* **SVM**: *Support Vector Machine* o Máquina de Vectores de Soporte. Hay varios subtipos: Lineal(svmLineal), Radial (svmRadial), Polinómico (svmPoly), etc.

* **Árbol de Decisión**: rpart
* **Redes Neuronales**: nnet
* **Random Forest** o Bosques Aleatorios: rf

### Checar accuracy para elegir el mejor modelo

# 1. Modelo con el método svmLineal

```{r message = FALSE, warning = FALSE}
modelo <- train(Class~ ., data = entrenamiento, method = "svmLinear", preProcess = c ("scale", "center"), trControl = trainControl(method ="cv", number=10), tuneGrid = data.frame(C = 1)) #Cuando es svmLinear 

resultado_entrenamiento <- predict(modelo, entrenamiento)
resultado_prueba <- predict(modelo, prueba)

#Matriz de Confusión
mcre <- confusionMatrix(resultado_entrenamiento, entrenamiento$Class)
mcre
mcrp <- confusionMatrix(resultado_prueba, prueba$Class) #matriz de confusión del resultado de la prueba
mcrp
```

# 2. Modelo con el método svmRadial
```{r message = FALSE, warning = FALSE}
modelo2 <- train(Class~ ., data = entrenamiento, method = "svmRadial", preProcess = c ("scale", "center"), trControl = trainControl(method ="cv", number=10), tuneGrid = data.frame(sigma = 1, C=1)) 

resultado_entrenamiento2 <- predict(modelo2, entrenamiento)
resultado_prueba2 <- predict(modelo2, prueba)

#Matriz de Confusión

modelo5 <- train(Class~ ., data = entrenamiento, method = "nnet", preProcess = c ("scale", "center"), trControl = trainControl(method ="cv", number=10)) 

resultado_entrenamiento5 <- predict(modelo5, entrenamiento)

#Matriz de Confusión
mcre5 <- confusionMatrix(resultado_entrenamiento5, entrenamiento$Class)
mcre5
mcrp5 <- confusionMatrix(resultado_prueba5, prueba$Class) #matriz de confusión del resultado de la prueba
mcrp5
```

# 6. Modelo con el método rf
```{r message = FALSE, warning = FALSE}
modelo6 <- train(Class~ ., data = entrenamiento, method = "rf", preProcess = c ("scale", "center"), trControl = trainControl(method ="cv", number=10), tuneGrid = expand.grid(mtry =c(2,4,6)))

# Conclusiones
El modelo con el método de random forests presenta sobreajuste, ya que tiene una alta precisión en entrenamiento, pero baja en prueba.

Acorde al resumen de resultados, el mejor modelo es el de **rpart, svmLinear o svmPoly**
